Have you ever wondered how life first got started on Earth? So do scientists! Though the question has not yet been fully answered, a careful study of Chemical Evolution is beginning to shed light on this mystery.
In this film you will learn what Chemical Evolution is, how it works, and how it is different from Biological Evolution.
This animation was paid for by the Center for Chemical Evolution, the National Science Foundation, and NASA!

Great video. As a biologist i love seeing concise scientific media targeted at educating the general public. Its not easy to simplify complex topics into a package that can be understood by people that don't necessarily come from a scientific background, but in this instance you have nicely covered the main processes but left enough to spur on those with a healthy interest to seek further information .It seems like you have amassed the right people for the job. Keep up the good work.
fuzzyhaggis and thank you too!! This was a brilliant video. Made wonder about viruses and their role in sculpting life. As a biologist, have you any information you like to share about your work and or knowledge of virus and cell relations that amazes you? I’m curious and this stuff fascinates me!!😊
Agreed. This channel is amazing. Simple enough to easily follow along and yet not too dumbed down to be incorrect. It deserves millions of subscribers.
Abiogenesis is an embarrassment!
Genetic information is the result of a mind, not unguided natural chemical processes!
RNA is being produced in advanced laboratories with intelligent chemists guided conditions and designed equipment!

This blew my freakin' mind. So 6:30 would essentially form a primitive lipid bilayer? Then like a billion years later, that series of chemical reactions is still going... and I'm one of them (O__O )

Our universe is crazy.
But the only reason we think so is because we inhabit, interact with, and are normally aware of only a sliver of it most of the time. The methodologies of science allow us to peer in to those aspects of our universe we don't normally have access to.

And your inviornment creates input in your brain due to impulses of your enviornment and neural plasticity it creates who you are !! And what you do! You think you make choices? :D lol we have no free will. Your brain is a pattern matching machine which is constantly addapting due to impulses and strengthening certain pathways in your brain that help you forward. You don't choose something... it's your brain making a choice all deterministic based on your past from birth untill now. Damn i didnt ask for this.
Curse you, balls of fatty acids!
Who do I blame for my awareness?
Why did I just find this channel? You're so good I'm going to share this with anyone who cares to listen.
The best evolutionary biology source on RUclips and most importantly understandable to laymen.
sup brotah!? how's the fishing going?
Not good, so many fishing ships around.
I'm a more super science geek, I memorised the human reproductive system when I was 6 or seven, but a six year old beated , memorising the periodic table of elements
Indeed. I wish the channel had millions of subscribers. But I guess 9 year olds are gonna Pewd.
I've been exposed to a lot of material pertaining to evolution and at no point was chemical evolution mentioned. I always wondered how chemicals made a transition into life and this video was very insightful despite not being able to provide an answer.
ゆい714 It might be because there's still a lot that we don't know in the area.
+ゆい714 Another interesting fact is that through a complicated process, segments of RNA have been found to form randomly in nature, so theoretically RNA plus amino acids plus ribosomes plus fatty acid membrane = the first cell.
+ゆい714 I watched this video a few years ago, very well done. It took me like 10 minutes to re-locate this link, so... please watch.
Science marches on. The human genome wasn't defined at all 25 years ago. 75 years ago we didn't know the function of DNA. Now we know what the typical genome is down to its bases, and a very large amount of the genomes of the life around us to boot. Chemical evolution started with the experiments of Miller and Harold Urey 65 years ago, though it wasn't called that at the time.
Wait what? It did provide answers. We haven't confirmed them but that doesn't mean they are not answers. And you wouldn't have heard any of this in evolution books because it has nothing to do with biological evolution. You have to have biology first, and molecules, no matter how complex, dont count.
I really hope that this informational gap can be closed soon, its so annoying seeing all these people acting as if they are right about the origin of life just because we don't completely understand it.
They still won't believe it.
Jake K. yeah but it will slowly close in on them. Then the creationists would be the minority.
Creationists are already the minority.
Vampyricon If you believe god created the first life form you are still technically creationist.
I think the more fashionable opinion amongst moderate religious people (along with institutions like the Vatican) is that god created the conditions necessary for life to arise. That still implies 'creation' of the universe but not specific guided creation of life. However you are correct that the opinion of 'gods hand' always seems to lie just beyond the current understanding of science.
You are discussing very complex scientific topics in the simplest way, while it's still accurate. Many thanks for your valuable videos.
to be clear evolution is defined as descent with inherent modification so abiogenesis can't be a part of evolution. However the word evolution can be used in different ways so here the word evolution simply means change over time.

If we can truly demonstrate that chemistry can give rise to the most basic form of a reproducing organism, then we'll really know for sure how life was created. This is amazing. Great documentary! Although it is theoretical, this is the best informative video I've seen in a long time. Subscribed~

The vector/cell shading art style paired with great content make these some of the best educational videos on RUclips. Thanks and keep up the great work!
this is a great channel, ive only watched two vids up until now, but im looking forward to watching a lot more
there was an some article i read once about this guy theorizing that life naturally occurs because of the attraction between different combinations of atoms. which of course is what this video is talking about. I find that extremely interesting, first because it seems logical and that if its true life isn't accidental it's inevitable. I love thinking about these sort of things. I can't wait to watch more of your videos. perhaps a video about thermodynamics!
you have the best videos on evolution topics that i have seen
Woa! My husband & I went to a Science Cafe event in Athens GA. Chris Parsons came and presented a few of the videos. Today is a rainy Sunday & we are going to spend the day watching all the Stated Clearly videos. I sent them to my son's highschool chemistry teacher in British Columbia - including " What is the Miller Urey Experiment" which mentions research being done at SFU. Thank you for making this videos! They are excellent!

His video series explains the next stage: ruclips.net/video/ckrBhL2T95A/видео.html
They become bigger spheres
That takes 1 billion dollar R&D fees. The lipid ball is never visible by microscopes. You need electron scanning. 1 million down. Now you can add some RNA in the sphere. 3 millions for the RNA synthesizer. Then you need virus to splice and see what the RNA is changing into. 3 millions down for the virus lab. Then you get sequencer to see what the virus changes into to figure out what what the molecules in the sphere are. 3 million for the sequencer. Now we are talking. And we can look for isotope methods to determine what molecules are inside the sphere and outside the sphere. 1 million for purified isotope carbon, deuterium, nitrogen. Your budget runs into 10s of million dollars within the first 5 days of lab work.
This is about the best explanation I've come across. Usually either there are missing steps or the explanation is far too arcane. Well done and thank you.
When I next get paid I'm donating to this channel. The videos are so beautiful to watch.
The cockroach attack gag and the flying squirrel were wonderful. I enjoyed this video :-)
"Reproduction is an extremely complex process"
Boy i'll tell you
Lmao dude
Bruh
It’s a huge leap in complexity from a fatty acid membrane to a living cell. It takes a leap of faith to believe random chemical interactions can form living organisms. The simplest among them are exponentially more complex than anything that can be observed to occur naturally or under lab conditions.
Juan Valadez what if I told you that the first cells were actually very simple not nearly ass complex as today after billions of years of evolution. The process by which molecules can make copies of themselves and are thereby selected created the first cells. These selfreplicating molecules are subject to replication and mutation such that new molecules can evolve that execute any number of functions. No need for a leap of faith. Just molecules and lots of time. ☺️
"what if I told you that the first cells were actually very simple not nearly ass complex as today after billions of years of evolution._
I would say that unless you show that for a fact then it's hocus pocus creation of imaginary beliefs, just like when Christians imagine their One Man, Jesus rose from the dead. Similarly for their imaginations of a creator/creation. When we don't know stuff, it's best to make that our position.
What if I told you that the first cells were _actually_ (i.e. really and truly) ... You don't have an _actual_ basis which is why you have to use words like "what if I told you", you may as well use the words can't you imagine. You're using words in the place of substance, but the thing is words without substance to point to have none.
What if I told you to imagine it the way I say which is just the same as religious people saying read my book and imagine life and creation and life coming about that way. Same principle, no evidence.
In the absence of evidence it's best to stick to nescience.
'Great' evidence there, "what if I told you" ... why don't you try, "what if I showed you" and then show it, yes point to it in reality, that would be great.
It's a gap of knowledge on your end Juan, this is the entry level to the topic, not the complete field of study.
And of course our mind wants to invoke magic the moment we lack knowledge, that is why we have flat earth, aliens, living Elvis, jeti, ghosts,... the list of magic patchwork never ends.
david fenton great analysis of the first 5 words I’ll use. I’ll just wait here for you to adress my point.
Hi Daiku Coffee. You wrote "The process by which molecules can make copies of themselves and are thereby selected created the first cells." Ok, demonstrate. Cheers.
It is indeed chemical evolution stated clearly. And informatively. Thanks John Perry
You said it so clearly ! Not like other channels with vague sentences even better than PBS channels .
Wow
you use the word 'cause'. I believe that 'randomness' is more accurate. Even humans have an average of 70 dna differences.
When one of the these changes happens to have a positive effect, then it will be passed on. And it's that simple. A harsh environment doesn't 'cause' evolution, it just opens a window.
causality does not infer intention.
The mutations themselves are random with respect to function, but selection is not. The vast majority of mutations that happen are bad for function but some are randomly good, just because so many changes are happening in so many organisms. The harsh environment is what turns it from random accumulation of mutations into adaptation.
I like how you're exploring the origins of life with the currently accepted theories or hypothesis, instead of the sadly recurrent "we don't know" or "more research is needed" that this field usually yields!
Thank you for these videos! I'm earning a degree in physics, so obviously I don't know enough about evolution. These videos help me to understand it. They're *stated clearly.*
The theory of evolution claims life began with a single self-replicating molecule 3.5 billion years ago. It doesn't talk about the origin of life, a necessary prerequisite, without which there's no biological evolution on earth. Thus, if origin of life from dead matter is scientifically impossible, so is biological evolution. The theory of abiogenesis claims, without any evidence or experimentation, life simply popped into existence from dead matter in the warm, primitive ocean (primordial soup) 3.5 billion years ago on a mindless early earth. This fairytale is not only a ridiculously absurd proposition hiding behind scientific language, but is also scientifically impossible. Many scientists have spoken about the scientific impossibility of abiogenesis (see details below).
In their desperation to make evolution true, evolutionists tell us to believe that life could have just popped into existence on a mindless early earth 3.5 billion years ago from dead matter, even though it's scientifically impossible.
Moreover, governments are often tricked into funding the "origin of life research" which is called a "scam" by some scientists (see below).
"Professor James M Tour (Synthetic Chemist) has publicly challenged ten leading OOL research scientists to synthesize organic molecules (protein, lipids, DNA, RNA, etc.) or a simple living cell! (Forget about creating from scratch, just try to put them together!) Dr Tour is included in the 'Top 10 chemists' in the world and one of 'The 50 Most Influential Scientists' in the World Today).
With the content of this video in mind, is it possible that life originated in the deep sea? hydrothermal vents along the seafloor would have provided very similar conditions to those found in the experiments exploring chemical evolution that you mentioned, and the harsh conditions of the deep sea could have been a driving motivation for early life to move upwards towards the surface "standard" ocean.
Totally possible, deep sea hydrothermal vents are one of the many locations being investigated as a potential origin point for chemical evolution for that very reason.
This is the simplest and most comprehensive video on this topic I have seen on youtube. I am not a scientist but rather an enthusiast. I am grateful. This is the first time it fuly made sense, subscribed.
I learn so much from your channel. Thank you very much.
Everything on this channel really is stated as clear as day
OH MY GOD i've been looking for a hypothesis like this my whole life !! i cant way to see if scientist will refute or come up with something better or whatever's next
THANKS
Don’t take the name of the Lord in vain
Wow! brilliant as always. Great job especially on the molecular animations. All to often animations of that kind of stuff don't do justice to the reality but you have done a damn fine job. Bridging the gap from the abiotic to the biotic is tough subject matter to get ones head around but I come away feeling like I understand this a great deal better.
These are really well done. Subbed.
This is ridiculously interesting! I definitely need to look into this more
Just gotta say that at @3:25 he makes a mistake. Oxidation of iron is a bad example of entropy because iron oxide is more "complex" then elemental iron. Its not going to reduce because it cant without energy being applied, same reason why stars can't use iron as fuel. Iron rusts because oxygen is being added it, a chemical reaction is happening that is ADDING to its energy. Oxidised iron is only pseudo-stable because we have an oxygenated environment and enough warmth to provide the energy for the reaction to take place, take these things away and elemental iron will sit there "forever".
Very good description. Also appreciate the fact that the atmosphere of ancient Earth was much more reducing than it is today.
Fascinating!!
Great animation!
This shows how strong your understanding about the topic is.
youre back :)
white You're*
This video has really good animation and audio! Crisp, colourful and very satisfying :D And the content is very good as well.
Unsure if it's a good idea to call this "chemical evolution" instead of just "chemical reactions."Creationists like Kent Hovind base a lot of their equivocation laden 'arguments' on the word, chemical evolution, sounding like biological evolution. I've rarely seen the term in papers or textbooks, and there are many fine synonyms, so It's probably best to avoid the word since it can be abused by spreaders of misinformation.
unassumption Chemical evolution is what it is called by the people who study it. Thus, the NASA funded "Center for Chemical Evolution" centerforchemicalevolution.com/
unassumption nobody should modify their definitions because people don't understand the terminology and are motivated to discredit the ideas therein.
Tjaart Blignaut like gay marriage? Marriage being defined as between a man and a woman shouldn't be changed just because a few people want it to.
G0Dork I never said definitions should not change at all. Besides that is a completely different issue and not relevant here.
G0Dork Not to mention marriage itself has NEVER been defined as a man and woman union. That is a purely Abrahamic construst developed hundreds of years after the concept of marriage. Many ancient cultures considered the idea of marriage independent of gender.
This was quite a gem to find after finishing O chem. We learned how the fatty acids would begin to group like that (soap). But to then transform into shells as they did here... how neat!
Another beautiful occurrence in nature is the random spontaneous production of the *phospholipid bilayer* (an important constituent of the cell membrane). Shake individual phosphate and lipid molecules about in a water chamber, and they "engulf" other *macromolecules* contained within the water. Simply by virtue of their innate *chemical properties,* they naturally coalesce to *form bonds,* wrapping into a *pocket* or a "bubble" around biological and organic proteins suspended throughout the "primordial soup."
*No magic, experiments, artificial intervention or intelligence necessary in the formation of the phospholipid bilayer!*
I am not a creationist but we dont still know the true "why". We dont know why things have innate chemical properties. Because this "magic" still exist
"another beautiful occurrence" uhhh that's what this video is about from around minute 6 to minute 7...
Well, shaking individual phosphate and lipid molecules is an artificial intervention. Lol jk.
Soap bubbles are magic :P
@@feynstein1004 - it isn't like processes in nature can't shake things
Stated clearly is my favourite channel on RUclips. Keep it up guys.
I need more of this.
I kind of understood some of this but this video really clarified it. With the origin of cell membranes explained also the fact that RNA can be created in the lab that self reproduces, it becomes clear that it's not a rare impossibility for life to form, but an inevitability given the right conditions. This leads me to believe that all planets that can support simple life, will create it chemically. I think we will find that Mars had life when it was wet and Europa might have something too. Being that for about three billion years, Earth's history revolved around singled celled life, it leads me to believe that the leap to eukaryotic and further to multi-cellular life is much less common. Earth just happened to be stable for a very very long time.
This needs to be mandatory to watch in our schools.
It wouldn't need to be if it wasn't for bigotry and ignorance
One of the best videos on evolution.
It would be really cool if we could recreate these conditions in a lab and see if some new living thing can be created, different from everything we know now.
I agree it would be cool , the ethical questions that would rise would give a political shitstorm tho.
Hmm yeah. But is it wrong if it's a very simple organism without consciousness?
People already tried that. Nobody succeeded yet.
MultiSciGeek And wait millions of years until first signs of live wil emerge? Nty
problem might be that it takes too long to form anything complex enough to be considered life. add to that the fact that its unknown if life can even happen in a way thats much different from our own.
When a living cell divides, its membrane splits into two. The mecanism for that might not depend on the cell being alive, with genetic material.
This is of course a wild speculation. But if such a mechanism were found, it could be a precursor to a living cell.
Lars, this can happen. I talk about experiments on this in the "what is life" animation. The problem is, no mutable structural information is transferred in the process. Liposome growth and splitting is similar to a fire growing and splitting, it doesn't seem like a true precurser to life because "offspring" don't enherit parental traits with modifications. That said, there are still a few labs playing with this sort of concept. Some metabolism first hypotheses make use of growing/splitting liposomes.
L-form bacteria are an interesting topic. They lack almost all of the replication machinery of modern cells but can divide. Most of the complex replication machinary is due to the cell wall, without that a cell just needs to fill itself with fat (1 gene suffices to produce that) to "bud off" another cell.

Stated Clearly It's ALIIIIIVE! I thought you weren't going to make any more videos.
The reason no one
but me has solved this problem is that people can't see the forest for the
trees! What does life use to make things happen? Proteins. What are proteins
made of? Amino Acids. Why are amino acids good to make proteins? They
self-assemble into repeatable structures spontaneously. Where can amino acids
be found? Every comet, asteroid, and meteorite. How did the volatile elements
get to earth? The heavy bombardment. What have recent experiments have shown
about comet impacts? That they unite amino acids into polypeptides. The
simplest life forms use multiple small polypeptides to make RNA!!! Now we just
need to know what conditions made it possible for polypeptides to unite and
make RNA from other Amino Acids!!! Just like organisms do to day!! All
biological molecules begin with Acids Acids!!! Currently astrophysicist published articles
stating most of our carbon, amino acids, and all volatile compounds were
delivered by meteorite impacts. Recently Prof. Jennifer Blank showed how the
impacts united amino acids to form small polypeptides. Today E.coli and simpler
organisms use small polypeptides that unite to make RNA from other Amino Acids.
Why when amino acids are ubiquitous, can be made from any mixture of compounds,
and self-assemble into repeatable structures would we expect it to have
happened any other way. These Polypeptides, like today, would have easily
united without help or exotic conditions and produced RNA. Which would have
been united by other polypeptides to form the first replicators; which still
exist today. They are called Viroids: strips of RNA that replicate in
plant cells and do not code for any proteins. These are the latest
reports. For how exactly all this formed Life you need to read my book:@Emergent Chemical Evolution: How Life
Started with Modern Published Evidence 1, Eduardo Hernandez - Amazon.com

That solves the chicken-and-egg problem! The answer is, neither!
the amniotic egg evolved millions of years before anything even remotely resembling a chicken ever evolved.
The chicken and egg problem is usually understood to be about chicken eggs, not just any old egg. That is, "What came first, chickens or chicken eggs?". In this case, the answer to the question depends on how you define "chicken egg". Is it an egg laid by a chicken, or an egg from which a chicken hatches? Chickens evolved from non-chickens, but since the process was general, the point at which you say "this is the first chicken" will be arbitrary. But no matter where you choose to set that point, that chicken will have been hatched from an egg laid by a very similar non-chicken. So under the definition "chicken egg = egg chicken hatches from", the chicken egg came before the chicken. However, that egg was laid by a non-chicken, so under the definition "chicken egg = egg laid by chicken", then the chicken came first.
answer = "dinosaur egg"?
The egg laid itself.
Physics Bitch!
The egg came first, the thing that laid it was different enough to not be classified as a chicken
Wow! Eye opener! These videos about the steps of life emerging from chemistry are much needed!
Excellent video. Understandable to a 8 yr old child.

"Chemical evolution is being investigated as a possible cause for the origin of life"
I realize that it's not wise to declare something a fact before fully understanding all the mechanisms involved, but by which other route could life have possibly come into existence? Is there any other reasonable explanation? (and I don't consider "god snapped his fingers and tadaah, life" a reasonable explanation ^^)
Nope. Though sometimes advocates of panspermia think so when they forget that it still had to start elsewhere even if it arrived here already formed. Chemical evolution can cover a variety of different ideas, but by a wide margin they're the only plausible ones.
I think the point of Panspermia is that it *might* so happen that chemical evolution could have never produced life *on Earth* .
If that's to be the case, then Panspermia and Chemical Evolution will be working hand on hand, because the idea that life couldn't be brought forth by chemical evolution on Earth doesn't make it impossible for it to have happened on Mars, Panspermia's favorite darling.
I don't see the two hypothesis competing at all, it's just that while one is looking to find out if our planet could have come up with life on it's own, the other is looking into how life could have spread even if a single planet had the ideal ingredients to evolve it.
We can never come to a conclusion on a subject just because we don't have another viable solution. All concepts must be confirmed as true or false independently to whether or not there is a competing concept.
We can't predict what information will be available to us in a year, 5 years or 100 years from now.
If chemical evolution really was our only idea, but it failed as a theory, then the answer is 'we don't know.'
Truth is often stranger than fiction my friend. When dealing with the unknown, the best we can do is estimate probabilities. And anyone that is 100% certain about these types of things is inevitably wrong.
There is a high chance of extra terrestrial "infection" so to speak, because we found some building blocks of life among asteroids between Earth and Mars.
Which could mean we had some severe impacts at the time of first RNA occurrences, or by a long shot could mean asteroids from outside our system, possibly sent intentionally. Which could also explain why we haven't been able to recreate the natural conditions for chemical evolution.
And this is why you exhaust your line of research and not call it prematurely, inventing an answer without testing always leaves you completely wrong.
I really like this channel. I am glad I found it.

@@Angelmou sorry missed this. Bif you read what I said, I stated chemical evolution, chemicals do not include biochemicals which you have put forward.
Chemistry is miles apart from biochemistry as chemists can not synthesis biochemicals as found in biology. For example all nucleotides and amino acids, which can appear naturally in a chemical environment, when synthesised are racemic.
@@iain5615 ??? The topic is how specific laws and mechanism gain and interlock the biochemistry.

It's a huge jump from a ball of fatty acids to a cell wall made of proteins. Even if the environment was favorable to the production amino acids and they were coming together to make proteins, there is too many useless combinations for it to have happened in less than 1 billion years on earth or even in a trillion trillion trillion years. And that's to make a single protein. Yet alone all the proteins needed for life and then for those to assemble into useful mechanisms as well as for complex RNA and DNA structures to form.
Then mutations happened to make things such as a leaf bug that perfectly resembles the leaf it is mimicking. All these odds have been beaten on one place in a short time of a few billion years. To an uneducated person a billion years may seem long enough. But to a mathematician it is a severely insufficient amount of time. It is an anomaly most evolutionists like to gloss over because it requires much faith in the impossible to believe that life can spontaneously generate anywhere in the universe. Even Sir Fred Hoyle admitted that it is damaging to the belief in evolution yet he says it had to have happened because here we are. That sounds like circular reasoning to me.

"It's a huge jump from a ball of fatty acids to a cell wall made of proteins."
You mean, a cell wall made from a ball of fatty acids and integral proteins?
Liposomes will assemble spontaneously in water from phospholipids. Any sort of protein that has a nonpolar domain could theoretically become integrated into it. Just because we don't have comprehensive models for the fifty billion possible transition forms of a liposome to the basic cell doesn't mean we need to plop an all-powerful man in the sky to make the pieces fit.
"Then mutations happened to make things such as a leaf bug that perfectly resembles the leaf it is mimicking."
This is a COMPLETELY warped view of evolution. It occurs GRADUALLY. random mutations resulting in ugly brown splotches on the insect 500,000 years ago could have been the precursors to mutations creating patterns beneficial for camouflage.
"All these odds have been beaten"
Expect for 99% of all life that has existed on the planet, which has obviously NOT beaten the odds.
+Brandom Landon There is no chance, this can lead to create a living cell, or even DNA, that is capable to work or reproducing. No fear. This is not way, how life was made, it could not be by random accident of connecting some fatty acids. Every smarter scientist, that had deep enough knowledge of molecular biology, admited, DNA is too complicated to be made by random connecting of everything, it has intelligence inscribed to it, so there must be creator with intelligence.
Cell membranes aren't made of proteins. They contain proteins but the main idea remains the same - they contain fatty acids. That's why the main components of a cell membrane are phospho- *lipids!*

This is incredibly good work. I watched it and watched it again. Thank you so much
I’d love to understand how the very first living organism was able to eat, digest, poop, urinate, breathe, reproduce and be mobile? The digestion system is very complex on its own. If this organism isn’t mobile how does it find a mate? Where does it’s mate come from? Millions of years of evolution doesn’t work here. Did it wait millions of years for some other thing to spontaneously appear? How did it just have a way of taking in oxygen? RNA and DNA break down in water, how did RNA and DNA survive? How did this organism live long enough to evolve DNA? What came first it’s heart or the blood? With modern tech we understand how complex a single cell organism is, something Darwin did not have, how is this complex cell possible? How was this organism able to intake oxygen? It rained for millions of years on the crust of the earth? Where did the clouds come from? How did they form? Today we get clouds from water evaporating. The earth was a hot molten ball that slowly hardened, where did the water come from? Where did all the chemicals come from? How did we get gold and lead? When one thinks critically and really questions these things they don’t make sense. I GUARANTEE no one can give me an answer. Just answer where the water came from on a hot molten ball, doesn’t heat evaporate water? Couldn’t come from the vacuum of space. Makes zero sense how the first living organism was able to eat, breathe, poop, reproduce!? Millions of years for simple changes cannot account for this, quick evolution cannot account for this. If this thing cannot reproduce it’s done for, even if it multiplies itself how would that be possible? It was just zapped into existence from soupy mud and had a way to reproduce? I call bull.
"I’d love to understand how the very first living organism was able to eat, digest, poop, urinate, breathe, reproduce and be mobile?"
first organism wouldnt be able to do any of that.
not in the sense you are thinking of.
it doesnt need a mate because it reproduces by replicating itself. have you heard of mitosis or meiosis for example?
no, it didnt wait for millions of years.
it reproduced for million of years.
and each descedant would be slightly different from its parent.
it didnt take oxygen. there was no oxygen on earth back then.
oxygen was introduced on earth by cyanobacteria around 3.8 billion years ago.
they didnt break down in water because they were protected by a micelle
organisms dont evolve the dna during their lifetime. so they dont need to live long
they reproduce instead and their offspring have slightly different DNA from them.
"With modern tech we understand how complex a single cell organism is"
yes today single celled organisms are complex, they were evolving for 3+ billion years.
first single celled organisms wouldnt be this complex.
you dont know how clouds form?
water evaporates....
water comes in a form of ice on meteors that were falling on earth for millions of years
yes, earth is molten rock and that ice evaporates and gets stuck in the earths gravity, it forms primitive atmosphere and clouds.
chemical elements are formed inside stars.
stars are fusing hydrogen and helium into heavier elements.
and at the end of their lifetime they explode and release most of those elements into space.
which forms planets and new stars.
gold and lead are formed in inside stars
"? When one thinks critically and really questions these things they don’t make sense."
yes it doesnt make sense when you dont know anything about anything.
" I GUARANTEE no one can give me an answer." i just did.
Wow what a lot of questions. So I’ll start with the first question. You asked how did the very first living organism eat, digest, poop, urinate, breathe etc.
The first living organism was a single cell, where all of those actions just diffused in & out of its outer membrane. You don’t need a digestive system if you are a single cell, everything happens inside your single cell. We have examples of organisms that live just like that today. You don’t need a mate and you probably reproduce by simply dividing yourself. So they are copies of the original.
@@budd2nd LOL this is comically absurd... there is no such thing as a "first living organism was a single cell" 😂🤣😅
@@anthonyoctaviano9055
You - “there was no such thing as the first living organism was a single cell”
Were you there? No you weren’t. We can study single celled organisms today, and that is how they digest their food and excrete waste. Straight through the membrane. So it’s totally possible.
What evidence (properly validated scientific evidence) do you have that it was not like this?
Earth's water could easily have come from the vacuum of space, in the form of comets and asteroids. Upon impact, this water would have evaporated and formed clouds at high altitudes, going through the water cycle until today

No fukwit. Scientists don't teach hypotheses as facts and no scientist I've ever met, worked with, or read has claimed to "know it all".
a very good video and could you make a video on how some proteins work (some complex some simple) thanks :)
In Darwin's time they thought a cell was simple. Now it is known to be astonishingly complex. All cells are. To replicate itself, a cell needs DNA. This requires both a precise sequence of digital code and a mechanism to translate this code into instructions for proteins, molecular machines and a vast number of other crucial functions. All of these function together like clockwork. Natural selection can't help since that would be only after replication begins. Thus, it has to get everything right the first time. It would be like making up a language from scratch on the spot and simultaneously writing a book in that language.
You can't assemble a protein without DNA and you can't make DNA without existing proteins. It's a chicken and egg problem. If the odds of something are 10 to 50th power it is considered by science to be mathematically impossible. To randomly assemble a single protein of only 150 amino acids long in the required order is 10 to 74th power, assuming all the required left handed amino acids are conveniently available! Exponentially beyond mathematically impossible. How much more unreasonable for an entire living cell with it's numerous crucial cooperating parts to come together spontaneously! There is nothing in "how chemicals behave" which would cause them to be compelled or inclined to self-assemble into a cell.
Here is the deal. People want to believe there is no Creator. Then they have impossible problems like this one. Since life exists, they figure somehow cells must have once self-assembled from lifeless chemicals. This is despite the fact scientists can't even come close to doing this even in controlled ideal settings and admit how unlikely this would be. Thus, proponents try to mitigate the impossible by appealing to millions of years or billions of galaxies as you did. This is just a smokescreen to obscure the difficulty and claim the impossible is inevitable.
Let's say someone's favored theory requires a turtle to jump over a skyscraper. Suppose they told you, "If you just have enough turtles jumping for long enough, surely one of them will succeed, because that's what I need to happen." Would you find that a convincing argument, or would you tell them to reconsider their theory?

*"To replicate itself, a cell needs DNA. This requires both a precise sequence of digital code and a mechanism to translate this code into instructions for proteins, molecular machines and a vast number of other crucial functions. All of these function together like clockwork"*
No they don't. All modern cells are DNA-based but that evidently hasn't always been the case. DNA isn't digital code but it's true that DNA requires proteins to replicate; no such restrictions exist on RNA or self replicating proteins though. The "RNA World" hypothesis postulates that the first life was RNA based, not DNA based. RNA can replicate on its own without the need for protein assistance and requires only a simple mineral catalyst to get going.

*"You can't assemble a protein without DNA and you can't make DNA without existing proteins"*
You can do both of those things. DNA can be formed by simply exposing RNA with a suitably strong reducing agent and prions are self-replicating proteins that work without DNA or RNA assistance.

That's a red herring. Chemistry isn't random.
*"There is nothing in "how chemicals behave" which would cause them to be compelled or inclined to self-assemble into a cell"*
Yes there is. To date there isn't a single reaction required of abiogenesis that hasn't been replicated under laboratory conditions. Life isn't an act of random chance, it's an inevitable result of the chemistry of the pre-biotic Earth.

No child, science isn't some kind of gigantic conspiracy to deny the existence of your particular version of God. I suggest you stop reading conspiracy theorist blogs for a moment and actually familiarize yourself with the research. Some of the stuff you're getting wrong is stuff most 12 year old's understand.
*"Thank you for your consideration of this topic. For more complete discussion and references see this link: [insert link to conspiracy theorist book here]"*
No, if you want to talk science then you have to cite scientific literature as your source otherwise it's just random conjecture. Of course other conspiracy theorists believe your conspiracy theory, the issue is that nothing you've said is actually supported by science. It's either a deliberate misrepresentation or flat-out wrong.
+John Pizzo We don't yet fully understand every step, therefore god. Is that your point?
Being unable to replicate something in the lab is not a legitimate criticism, by the way. We can't make a sun in the lab, but they undoubtedly exist and they are emphatically NATURAL objects.
+SimplyReg Nope, that is not my point.
"God of the Gaps" is no one's belief. It is simply a straw man concept constructed by evolutionists solely for mocking.
"Not yet fully understanding every step, therefore god" would be more analogous to saying one doesn't fully understand how a carburetor works, therefore a car requires a designer and builder.
What I am saying is a cell is like a sports car, complete with it's own car assembly plant; and an owner's manual written in a language made up on the spot for the occasion which robots use to build and maintain the car; and a plant fabricating parts out of raw materials while we are at it.
Chemical evolutionists are the guys saying, "Why don't you believe that?", and I'm saying, "Because that's ridiculous!" The burden of proof is on the one proposing impossible things. A cell self-assembling from lifeless chemicals is one of these. Understanding the car/cell better doesn't eliminate the need for a designer/builder. If anything, the more detail one understands the more obvious such could not come about at random.
If something happened unaided in some pond somewhere, then why couldn't a scientist with limitless materials and tools do similar? By the way, who does the capable, intelligent scientist in the illustration represent?
Making a sun in a lab is "apples and oranges" to making a cell. A sun is extremely simple compared to a cell, basically requiring only lots of hydrogen and gravity to assemble. Besides the matter of scale, if one "can't make a sun" in a proportionately sized lab, you are only reinforcing the point.
John Pizzo Except it is proven, I even went into excruciating detail to explain it to you with citations at every point. You just ignored the corrections because you don't actually care if what you believe is true or not. It's not a matter of you saying "It's ridiculous!" it's a matter of you asserting that it's ridiculous because it's too complicated for you to understand and then plugging your ears and screaming "lalalalalalala" when someone tries to explain it to you.
You'd rather indulge yourself in your little conspiracy theories than actually be right.
"The burden of proof is on the one proposing impossible things. A cell self-assembling from lifeless chemicals is one of these." It is your assertion that these things are impossible. Chemists and physicists have demonstrated that complex chemical systems arise spontaneously due to natural physical and chemical laws. Self-replicating chemical species such as RNA, simple proteins and lipid bi-layers arise spontaneously under the right conditions. No-one is suggesting that a complex cell sprang into life spontaneously except you. What is suggested is that the first cell gradually evolved via an assemblage of naturally-occurring chemical and physical reactions, through far simpler but self-replicating intermediates.The scientists are working on demonstrating whether this might be possible and if so, a plausible mechanism.
You have stated that it's impossible for this to happen. PROVE IT.
Sir,
Your all videos are really so informative and interesting too.........
Thank you
Even if chemicals can assemble in sheets or balls, life is different. Life has consciousness with will to live, ambitions and aspirations, fear, desire, lamentation and many other emotions and these separates life from inert chemical assembly. We observe at the time of death of an entity all the chemicals are more or less intact and yet there is no luster and brightness and no conscious life??? Don't get fooled that only chemicals make life and we are going to make life by assembling insert chemicals. Apart from chemicals there is subtle superior energetic particle that animates each living body.
Do bacteria have fear?
this... almost made sense.
All entities eat, sleep, mate and defend. Defence is from fear to protect oneself. Some entities have far more developed defence system or ability to defend while others to different degrees and are more vulnerable. We can know presence of life when an entity undergoes these six changes or development in life. They are born, grow, mature, reproduce, dwindle (grow weak) and finally die. We can observe the presence of life force but our material science cannot directly detect the subtle conscious force. Only in the Indian spiritual tradition is the process to know and directly experience the life force.
