Natural Selection is one of the main concepts found within the theory of evolution. It was discovered by Charles Darwin and Alfred Russel Wallace though Darwin championed the idea in his book "On the Origin of Species".
Natural selection can be defined as the process by which random evolutionary changes are selected for by nature in a consistent, orderly, non-random way.
When coupled with descent with modification, Natural Selection can cause a population to evolve for fitness within a given environment over multiple generations.
Natural Selection is an observable fact. By carefully observing populations of living things with short life cycles you can actually watch it happen.

As a high school science teacher, I thought this was very well done--clear, concise, good use of graphics, and an authoritative, yet not condescending, tone. Great job!
Life adapts by keeping the useful gene while losing the useless genes
but it never created a new one, this is not the reality in which we live.
It is a fairy tale, contrary to observation and facts.
The theory of evolution is a dogma without any scientific evidence. It was introduced not for scientific reasons but for ideological reasons. There are no fossils that prove evolution. Millions of fossils prove no evolution. Living things did not appear by evolution but by the Cambrian explosion. And traces have been found that prove that people from the times when Darwinists claimed that people were half animals were fully human. There was no such thing as evolution. And countless studies in laboratories have failed to turn up any examples of beneficial mutations. Almighty Allah created living things not by evolution but by the Cambrian explosion. The functions of all organs, which Darwinists call obsolete organs in living things, have been revealed. In other words, there is no such thing as an expired organ in humans or other living things.
@@mauricemenard2243 That sounds like a creationist talkingpoint. How many different types of mutations do you know of?
cant belive there is someone out there who can explain things so perfectly and magnificently , thank you so much for the video ,it really means a lot
There is a population of Small Lizards that are Green, Agile and Arboreal. They live in a relatively humid tropical forest, with many lakes and fruit trees (the lizards' main source of food). However, due to a natural catastrophe, almost the entire biome of the region has changed. Many lizards died. The new biome is drier, rivers are scarce, there are few trees, and the vast majority of fruits have become extinct. There are only insects. After many generations, what do you think the population of the Little Lizards will be like?
been always confused about the term "natural selection". finally I got it. nature selects who gets to survive and reproduce. Thank you so much.
Not exactly.
Nature is only adjusting the abilities of the organism that enters the world. If the new ability does not work in its current living enviornment, and gets killed. Then that gene/ability won't get passed down. However if it's survive and get's reproduced, the gene get's passed down. So if you survive and pass on your genes that made you survive until you grew old and died, good job I guess.
hmm So nature selects which genes will be passed down. Isn't that the same as what I said?
No, nature is only "giving" or "adjust" the living beings in nature. If a disease is caused by a specific gene, but that living being who has it were succesfully give an offspring, that gene will be carried by the offspring. Which means, the disease is still "alive". Natural selection should be seen as sort of as a referee. It evens where things are unbalanced. For example; if "Alpha Animal" has total control over resources that are needed to survive, "Animal Bravo" will mutate for the lack of "strength" it needs to stay alive. It either adapts by adopting a new habit or a mutation will happen in its DNA. Somewhere around, a change will be happen to make sure everything is in balance. That is what natural selections job, as far as I know.
Oh I see! thank you so much for the detailed explanation.
my bio teacher really should use these videos. i actually understand this.

I am teaching high school Biology in Thailand (I am a native English speaker from the US) and these videos have GREATLY helped me. Thank you SO SO much for posting! :)
I recently discovered your RUclips channel, Stated Clearly, and wanted to reach out to express my admiration and gratitude for the incredible work you’re doing. As someone who isn’t a native English speaker, I’m amazed by how clearly and simply you explain complex biology concepts. Your dedication to establishing foundational ideas and reinforcing key terms makes your videos accessible to everyone, even when the topics are challenging. Watching your video on natural selection this morning was a true "aha!" moment. Although I've studied this concept in several psychology courses, I always found it difficult to fully explain. Your video made it so clear and straightforward; it felt like everything finally clicked into place.
First and foremost, thank you for your amazing videos and the hard work you put into making science accessible. Not only have I learned more about biology, but I’ve also picked up new English terms and scientific concepts, thanks to your approach.
Secondly, I want to encourage you to continue creating these fantastic videos. I can only imagine the time and effort it takes - simplifying complex topics, adding supportive visuals, choosing animations that reinforce understanding, and providing such authentic examples. Every aspect of your content is engaging, thought-provoking, and leaves a lasting impression. Not to mention that your calm and soothing voice makes even the most complex subjects approachable, almost like a meditation.
I noticed you haven’t uploaded new videos recently, only links to other resources. If there’s any hesitation, I hope this message serves as a reminder of the positive impact you’ve made on so many of us. Your work is loved and appreciated by viewers worldwide, and we’d love to see more of your unique, insightful content in the future.

As somebody who believes in God I can only laugh at those retards saying he personally designed all of our species from the beginning. Religion is truly a poison of humanity due it's assertion of revelation as a form of knowledge of God.
God is exist that exist in natural selected human’s imagination and human behavior.

God: yeah my product, what’s up?
Human: I’m wondering where did you come from?

Am I the only one here just cuz I'm interested and love everything about nature? School didn't teach me crap. Iv learned more off youtube over the past 2 years then I ever learned all through preschool to 12 grade
Not just you. I've learnt a lot off RUclips too. At a school parents evening my Dad pointed out to one of my teachers that if she could captivate me like Sir David Attenborough could I'd be a genius lol
were all doing homework that their biology teacher gave them right now
Yh I am😑
I have a test on this in a few days and this was really helpful. Thank you!
Nice one. I'm an animator/cartoonist, and I work at a science museum (North Carolina Museum of Natural Sciences). I'd be keen to learn more about what you're doing.
As advertised- the concept of natural selection is stated clearly, explained perfectly, and the animations are amusing and appropo to the narrative. Thanks. Keeeeep going!!!
In a way we can say that nature has some intelligence hardwired in itself (maybe the laws of physics). Many thanks for this video! I really enjoy the way of your presentations. Keep up the good work!
Flip a coin, and your chance of getting heads or tails is basically 50-50. Flip 100 coins and chance of all of them landing heads up is 1/2 to the 100th power - you could be flipping for eons without getting an all heads result. But instead of restarting every time. reserve the ones that show the right result, and only re-flip the tails. 100 flip, 50 heads. 50 flip, 25 up, 25 flip 13 up, 12 flip, six up... In only 5 iterations, you're 97% of the way to the result.
Genes and alleles are a lot more complicated than coins, but the experiment is being run billions of times over in parallel - each creature a new experiment, each generation a new flip, and the environment of predators and hazards the selection for the desirable trait.
HUH me a gamer
Tldr I still don’t know
Nah it's not 50/50 there's a chance of flipping it at the side
I must know: Is suicide considered natural selection?
+Mr. Potato It could be, if the suicide is caused by something hereditable.

I agree
Yes, because if suicide was dominant. Nobody would live. ;)
Herman Willems me being a total nerd but, suicidal behaviour would be a whole bunch of genes as well as a shitty environment to live in.
Thank you. This is an easily digestible summary of Natural Selection. It's very important that ideas, theories and indeed facts are made accessible to simpletons like me. By putting this into simple, bite-sized and understandable terms, you've helped in reaching the masses, most of whom (like me) are not super intelligent or academic, but who have a mind and want to use it, given the information to hand. Well done!

Most people are appalled when someone murders or attempts to murder a child. Even more so when it is a parent attacking their own child. It is universally condemned. Almost. Tell a true believer the perpetrator was Abraham and their response is “Oh, that’s different. God ordered him to do it”. Oh REALLY? Does that sound at all like a rational response?
And what kind of god would play a sick trick like that? Testing Abraham to see if he would do god’s will? Isn’t this god supposed to be omniscient and omnipotent? Wouldn’t he know beforehand? And what about “Thou shalt not kill”? Oh, excuse me, THAT didn’t come until LATER.
O.K. so later, Moses gets the 10 commandments, and chief among them is that “Thou shalt not kill” commandment. Now, everyone probably feels that is a good commandment that needs to be observed except perhaps in war or self-defense. Well, according to the bible there are other exceptions:
To those of you who see the bible as the inerrant word of god; you must be extremely busy, as true believers, putting to death adulterers (Deuteronomy 22:23-24, Leviticus 20:10);homosexuals (Leviticus 20:13), non virgins (Deuteronomy 22:20-21), and any of your neighbors foolish enough to mow their lawn on the Sabbath (Exodus 31:12-15,Exodus 35:1-3,Numbers 15:32-36). Your neighborhoods must be scenes of daily carnage.
And using the bible as a source of morality? Here is a wonderful example of biblical morality:
Numbers 31:14-18
14 Moses was angry with the officers of the army-the commanders of thousands and commanders of hundreds-who returned from the battle.
15 “Have you allowed all the women to live?” he asked them. 16 “They were the ones who followed Balaam’s advice and enticed the Israelites to be unfaithful to the Lord in the Peor incident, so that a plague struck the Lord’s people. 17 Now kill all the boys. And kill every woman who has slept with a man, 18 but save for yourselves every girl who has never slept with a man.
31:35 And thirty and two thousand persons in all, of women that had not known man by lying with him.
By any standards, that is pretty horrific cold-blooded murder of thousands of women and children, followed by the rape of 32,000 young girls.
Oh, and speaking of rape, surely that is one of the ‘Thou shalt nots’ of the ten commandments. NO??? Take a look at these REALLY important commandments (there are different versions within the bible).
Thou shalt not:
Worship other gods
Work on the Sabbath (death penalty crime)
Take the name of the lord in vain
Make graven images
Covet thy neighbor’s wife (ass, house, etc.)
And, oh yes, ‘thou shalt not kill’ and ‘thou shalt not steal’ are in there somewhere. But rape? Not one word!!!
How about elsewhere in the bible? Surely the bible must condemn it somewhere? Oh, yes, I found it. Deuteronomy 22:28-29
28 If a man happens to meet a virgin who is not pledged to be married and rapes her and they are discovered, 29 he shall pay her father fifty shekels[a] of silver. He must marry the young woman, for he has violated her. He can never divorce her as long as he lives.
YESSS! There it is. Rape is a PROPERTY crime. The rapist has damaged the father’s PROPERTY and it is he that must be compensated. What justice for the victim of the rape? She has to marry her rapist. Surely she lived happily ever after, no? Here, as elsewhere in the bible, women have no say in their future.
And slavery; you would think that the bible must take a firm stand against it. Think again.
Exodus 21:20-21
20 “Anyone who beats their male or female slave with a rod must be punished if the slave dies as a direct result, 21 but they are not to be punished if the slave recovers after a day or two, since the slave is their property.
These are NOT isolated instances, nor are they taken out of context; these themes are repeated over and over. They are not the actions of a just and loving god, nor do they have any semblance to morality.
It is a sign of the irrationality of religion that the ‘faithful’ will ignore or shrug off the most horrific acts in their ‘book of truth’
This is how religion degrades the human mind and destroys the ability to reason.
Its obvius you dont have a clue on anything more than an old book full of non-sense and fairy tales. Educate yourself, give it a try. Try to understand what evolution is about.

I would like to point out that the above post is NOT an attack on Christianity; but if your world view depends on your acceptance of Old Testament accounts as sources of truth and morality, you need to think again.

Evolution is not a theory. It is a *process*. The only thing theoretical about evolution is how it occurs, and natural selection is one theory that explains evolution to a great degree. Please don't say that "natural selection is a part of the theory of evolution" because that's just not correct. Otherwise...nice video!
Rod What is meant is something called *intelligent design* ..."You cannot get order and complexity from random chaos alone." The bodies and behaviors in nature is very complex and orderly. Just as the farmers selectively bred the best one, God selectively breeds the best in nature. They couldn't have originated from just probability (the randomness of decent).
@@anarchoniaism so Christianity is not theory cause it not have scientific evidence that can be directly observe?
Dana Krempels evolution is a scientific theory that explains an observable fact about reality. There is no competing theory to evolution. A scientific theory is the pinnacle of science.
Rod the lizard didn’t eat random bugs, it ate the ones that did not have the correct colouring for the environment. There’s nothing random about that.
The process is evolution is the theory (how it works). It is also a fact, however. Like gravity is a fact, how it works in gravitational theory.

Katya aa Can’t tell if you’re joking or not lol
Geology shows that fossils are of different ages. Paleontology shows a fossil sequence, the list of species represented changes through time. Taxonomy shows biological relationships among species. Evolution is the explanation that threads it all together. Creationism is the practice of squeezing one's eyes shut and wailing "Does not!"
You have a penchant for making assertions lacking supporting evidence. I have asked you repeatedly for any evidence, ANYTHING AT ALL, that would give any credence to your assertions of "supernatural force". And you remain strangely silent on the matter. It is however possible to prove God's existence. Proof of God is very simple. All it would take is a verifiable miracle. Miracle cures are too easy to fake; try a REAL miracle, the restoration of a missing limb. Reach out to some deserving Christian, a child would be best, and pray for that missing limb to be restored. If God is truly omnipotent, it is certainly possible. And Jesus has said on at least a dozen occasions that your prayers WILL be answered. So many times we have been told of people miraculously cured of cancer and other serious maladies, but not once has a limb been restored and the question must be asked WHY??? Does God hate amputees? Is it that no one has prayed hard enough? Perhaps God is really not omnipotent, but impotent. Perhaps Jesus lied and God's answer is "Fuck You". OR perhaps this religion thing is just a crock of shit.
@@RandallWilks master! I see this Christian who so smart and I want to learn more from you!
Amazing 2 videos. So much to learn it’s overwhelming. Came out of Christianity and took a liking to the brain and the cosmos, only reason I stayed away from learning more about evolution is never found someone that explained it in detail, simply.

I'm not really good at these things, so don't be harsh, but... is natural selection the thing that makes evolution work and vice versa?
Evolution is simply change over time within a population. Natural Selection is what shapes that change, making evolution move in a direction that allows a creature to better survive and reproduce within its environment.
Stated Clearly
Oh, I kinda understand now. Thanks for clearing things up! The video was rlly good btw X3
Derek Sheedy
The two components of evolution are mutation and natural selection. Mutations are (usually) small changes in the letters that make up DNA. They can be insertions, deletions or substitutions. If those changes occur within a gene (a portion of DNA that makes a protein), they may have some effect on the organism. If the effect is bad, the organism is less likely to survive and reproduce. Factors affecting survival would be predators, food supply, climate, etc. If a mutation allows the organism to more effectively deal with those challenges, it is more likely to survive and reproduce. The first, mutation, is entirely random. The second, natural selection, is not.
“It is not the strongest or the most intelligent who will survive but those who can best manage change.”
― Charles Darwin
Derek Sheedy You should check out another channel as well called Thunderf00t, he's a scientist who is really good at explaining Evolution more simply. :)

I only have one question: In the video, you stated that the tortoises are the descendants of individuals that randomly floated to the island. That seems highly improbable. How would there be enough arriving at a frequent enough rate to produce a healthy population where inbreeding was not a concern?
The Galapagos islands formed volcanically, they did not separate from the main mass of south america. Why does it seem so unlikely that animals would drift out there? I can easily picture that in my mind.
Thanks for the info about the islands being volcanic. Didn't know that. I didn't say impossible, merely improbable. Those are two very different words. An improbable thing is still entirely possible. It doesn't seem unlikely that some animals could drift there. It seems unlikely that enough members of the same species to form a healthy population could all drift there within a short enough span of time to breed with one another before dying. One or two here and there floating on some debris seems more than possible. I'm just confused as to how that could happen frequently enough to establish a population large enough that inbreeding would not be a significant issue.
This page talks about that issue:
www.galapagos.org/about_galapagos/about-galapagos/history/species-arrival-and-evolution/
+Edwin Luciano Actually, that doesn't provide any new information not mentioned in the video. It does, however, seem to imply that the number of individuals necessary to form a healthy breeding population (known as the minimum viable population) may be significantly smaller in some species than in others. For example, I believe for humans that it is around 160 or so, but it could be possible that for tortoises that number is much smaller, for example 20 or 30. That is the real answer to my question, and I had to infer it on my own. This information should really be explicitly stated on their website if this is the case.
It's worth noting that "minimum viable population" is a probabilistic concept. It's a number that answers a question of the form "what is the smallest population that I would expect to be alive in 100 years 90 out of 100 times, given what we know about various things like inbreeding, predation, reproduction, etc" there's a similar question for "5 out of 100 times" that could allow a higher rate of small rafting events to have the same outcome of one big viable one. A single population just has to beat the odds.
I’ve learned more in 9 minutes than in my entire semester...
No but for real, thank you very much, I have an essay on Darwin and Wiliam Paley due tomorrow and i didn’t understood what they were saying before now, it all makes sense now
People that actually understand Evolution add 0.1 ten times and get 1.0. Evolution deniers ignore 0.1 ten times so they get zero, because they think 0.1 is insignificant, unable to simultaneously hold 10 ideas that fit together. Deniers simply don't have the ability to concurrently view many puzzle pieces in the head winds of their fears, willful ignorance, and delusions.

I believe so lol
invisible pink unicorn is the common ancestor of horse.
So good! Clear, beautiful illustration, just got it everything. Thanks!

you would benefit from watching this.
But how does the turtle survive till it gets the neck to reach those cactus? Unless they where short to begin with.
There are three possibilities: a) the hights of the cacti and turtle necks co-evolved in an "arms-race"
b) a turtle with short neck can still eat cacti, albeit less efficiently than turtle with marginally longer neck.
c) the turtle originally evolved longer neck for different reason and it happened to be useful in this scenario too, further amplifying the effect.
HOLY SHIT Andre, who was the idiot that explained evolution to you? You need to hunt that sucker down and kick the shit out of him for making you look so stupid.
If you cannot understand that evolution is not one animal turning into another, then you are incapable of understanding the complexities of evolution. Go to school and get an education.
andre jones I think you are very close-minded. If you what to rely only on things that you yourself saw, then how do you know for example that moon has other side... hell how do you even know that neptune exists. Or how do you know your body is capable of dying - it certainly haven't died before...
Your examples does not really support your opinion due to your examples has actual current documentations and photographs and has been observed by others. evolution or significant survival of the fittest on a grand scale was not observed or documented.
Love it. Keep up the good work!
This is the best video on RUclips to make a religious person understand what natural selection really is. That is tough!! Can't wait for more videos from this channel!
answer this: What was the belief shared by most scientist till middle of 19 th century?
You'd be surprised how many creationists get this wrong.
Getting everything wrong is kind of their thing. I just wish they'd keep it to themselves.
Nope this is all wrong thor did it
what are you talking about. THOR?
Odin- hold my bear
Science is not stand for truth, science easy be moved and collapsed inspect to wrong.
So if natural selection be proved is wrong someday, that’s okay.
Sarcasm
for the science there ain’t rights and truth to believe in the world but all is the stuff we can suspect, inspect, adjustable and editable by science methods, science doesn’t receive the description that can’t be disproved, if the description can’t be disproved then the description be invalid. Natural selection theory is the mother theory of biology not because it can interpret what and predict what will be next to every creature we found in the earth and also it can be disproved.
I had to read text Book over and over yet didn’t understand. Other video also failed to have me understand the concept of natural selection. I finally now get it by watching your video. Thank you so much!!! Better than my professor and text Book:::
Hi Sophie, I just posted a couple of my essays above. Let me know if you find them helpful.
So nature selects the lucky animals who get to survive, how does that particularly advantageous mutation disseminate? Is it just that because they live, that mutation will live on through reproduction?
+Zain Chawdry you got it!
Thank you sir, you have earned yourself another subscriber!
Zain Chawdry And another one here!
Zain Chawdry are you an atheist ?
"GOD DID IT"
Tank u, someone wo understands
Wesley Snaggletooth The quotation marks meant that they were not my words, I meant it to be taken sarcastically. Sorry.
God bless you all
Wesley Snaggletooth I am an atheist, but I disagree when you say God has been proven not to exist. We have not, and probably cannot, prove or disprove his existence, although we can come to conclusions based off of what we DO know on whether the existence is plausible or not.
Hunter McClurg Well said mate...
you just gon make a dude wanna rap at the end
Excellent!
This is an exceedingly clear and concise, visually and sonically pleasing explanation of
Descent with Modification, Natural Selection, and Selective Breeding.
Who here got Told to do this For school
the farmer's wife looks so sad i hope she find happiness somehow..
Humans have tail bones wisdom teeth and curved backs
+phxtonash Yup and its believed that will go away one day
Although I do believe we evolved from primates, the primates we evolved from were ape like, but didn't have tails.
@@LosloTypical they lost them
PhxtoNash and a soul!!
My teacher showed us this in class and natural selection made so much more sense 👍🏼
+Randomly Awesome - I'm glad it was helpful!
Who else is here because of "Biology Class"
Sadly I am

the real question is what was exactly the first living organism on the whole planet and where did it come from ???? and how it did evolve into millions of different living organisms and what about the universe ansd who causes the big bang theory to happen and if it happend by itself !!!! where did this huge giant thing came from besides the million of other glaxies around us where did they come from ????? .....
*the real question is what was exactly the first living organism on the whole planet and where did it come from ?*
No one know exactly what the first life form was yet. It's not sure we ever will know since that form of life don't leave traces the same way more advanced and bigger forms of life do.
But we know that it arouse through a process that we call abiogenesis.
*and how it did evolve into millions of different living organisms*
What do you mean by how? Evolution is the process.
*what about the universe ansd who causes the big bang theory to happen and if it happend by itself !!!! where did this huge giant thing came from besides the million of other glaxies around us where did they come from ?????*
There is no "who" involved here. Before the big bang all energy in the universe were condensed in to one small singularity. At one point this singularity started to expand, that is what we call the big bang.
Explaining the big bang and also how galaxies form is quite big subjects. But if you are interested you can read more about them here: en.wikipedia.org/wiki/Big_Bang
and here: en.wikipedia.org/wiki/Galaxy
The Galaxy article got one part named Formation that you'll find interesting.
Hoops590 Oh, well. If you say so
Hoops seems to think his assertions constitute fact. Not today, not yesterday, not ever.
The thing with science is it's ok to say we don't know certain areas yet and we're trying to find out, if you think it's wrong prove us wrong in fact they like to be proven wrong, it doesn't profess to know all
my friend yesterday medicine was a black magic ........people thought you get sick because of evil spirit and/or curse today we cure evil spirit and curse with antibiotics yesterday we had another thought about disease so as god origin of life today
Those farmers are looking into my soul...
Ironseb OK
Thanks for clearing the doubt on the definition of "natural selection". I always got confused now whether it was random or not
I ain’t here for homework I’m just watching it out of curiosity anyone else with me ?
Ditto !! I was reading a psychology book just for fun and veered off to this topic ..lol
Got to admit the videos are so informative and entertaining.
Same binge watching Newton, Einstein, Darwin ,Michael Faraday ...and reading Tesla ,Carl Gustav Jung all randomly selected lol
fire fox I see
Virat Sharma gotta agree with you there bro Stated Clearly always gives good content and have you watched their video “Where Do new viruses 🦠 come from” if not then you should it’s an excellent video
@@rajveerbhardwaj8470 I presume you're from India. And if so, I'm glad that the country is going to do well with knowledge seekers like you . As the saying goes, knowledge is power. Best wishes!
4:53 they look like dwight and angela :0
Thank you for the wonderful comparison between "farmer" and "nature." I came to the epiphany that they are generally the same thing when discussing the topic of Natural Selection.
Are all of the comments initiated by creationist trolls?
I live to tell the tale, nature selected me for my superiority, yahooo, I am the best....
Have you descendants? Until you have the selection hasn't been made.
Imagine thinking that god made the earth instead of garfield
I am short of words right now about how fun and CLEAR was
I was born with my ring and index finger being webbed to each other. Like duck.
chances are, if you make love of your opposite sex with the same uniqueness, it is more likely that your baby will have that too, but i bit different. either enhanced of eliminated.
Jhaedi Avila Yes, that seems like a good thing because my child might be able to swim faster and pass on his "Webbed fingers" genes to his children and so on.
Mark Anthony Bulaon No its just a genetic mutation that caused my index and middle to have an extended skin joint.
andre jones No, i can't turn into human from a duck. Its just a genetic random mutation i think so.
You have no idea what your'e talking about, its very funny.
