You specifically mentioned humans, but this adaptation occurred in the common ancestor of placental mammals (almost all living mammals are placentals), which appeared about 100 million years ago.
I think syncytin-1 is only found in the placenta of humans and some primates, and it entered the genome 25 million years ago. (The video said 100 million years ago, but this might be a mistake.) Syncytin-2 is found in all primates and was integrated 45 million years ago.
and... apparently there are other types of syncytin proteins found in the placenta of other mammals (not all mammals), but they came from a different viral infections than the primate viral infection. So that means that viruses infected different animals at different times in history, and many of them incorporated syncytin into their placenta in parallel. If that's true, that's wild. www.discovermagazine.com/planet-earth/mammals-made-by-viruses

Sorry for the nitpick but assuming that the bit at 0:47 is correct there are more individual viruses than stars in the known* universe. It's a nitpick but decently important as we really couldn't know for sure how many stars are the in "the whole universe" as far as I'm aware.
As far as I know she is right. Stars are made of matter. There is an upper limit on the amount of matter, because above that limit the universe would contract because of gravity. The number of viruses is many orders of magnitude more in numbers than the numbers of possible stars, incuding the ones we can't see.
@@bpg786 Space is not infinite. It is growing and expanding in an accelerated rate driven by Dark Energy. But that does set limits on the amount of mass it has. If we assume that the stars we can't see are more or less similar to those we can see then we can calculate roughly how many stars there could be. The number of viruses is WAY larger. Note we are only comparing their numbers, not their mass or their sizes.
btw it is not correct “more viruses than stars” because we do not know how many stars there are in the whole universe, because we only know 4% of the universe.
@@robinhood4640 Means the statement "more viruses than stars" is basically equal to the 'theory' of knowing 4% of the Universe. Both are as you said "a stab in the dark".
Very interesting, once upon a time in the past the mice and rats did spread diseases but now in laboratories we use them to find and test new drugs to fight diseases. Maybe also one day the viruses which cause infection can be widely controlled and used to fight diseases too.
Biopharmaceuticals have been using viruses as delivery mechanisms (vectors) for years and have been hitting the market ever since. As viruses can infiltrate cells relatively harmlessly, you can modify them to deliver drugs into cells. That's how the Astrazeneca, J&J and Sputnik V vaccines work; they are adenovirus vector vaccines. They are also used for gene therapy. Also, there are viruses that hitchhike a ride in bigger viruses, maybe they can be utilised in some way too.
all placental mammals do and must have syncytin. As far as the research has been done, all the placental mammals have syncytin. I'm not a biology student but as much as i know, the connection between the fetus and the uteral wall won't be established in any mammal without the presence of syncytin. That is why 'Monotremes' and 'Marsupials' have developed different methods for the purpose. any further explanation would be appreciated and i'd like to know more.
@@grandunification6226 It is normally regarded as convergent evolution. For example, the primate and rodent syncytins are similar but not considered from the same origin. So you could say this placenta idea was reinvented multiple times.
Dude, the background music at the start is the exact same I hear when I load into my home world in VRchat and for a solid few seconds I thought I was tripping lol
Were like planets ourselves. And theres a balance in us between a bunch of different life forms. Like us, they will run out of resources and at times wage war. Its so endlessly fascinating. Everything that happens in us is the same way we run society. I wonder what conciousness is like for bacteria. We basically have the same nature. Even if we build high tech ships and leave the planet. Were like a virus that has finished off its host. Dark, but its so cool! I feel theres a lot to learn here.
What a perfectly illuminating video to answer the longstanding question what evolutionary purpose do viruses SERVE? A pivotal one is due to their ability to mutate the DNA sequence they're busy little factories for creation of novel proteins some of which had become the trade mark for even human evolution such as the placenta protein which makes fetal development possible
More individual viruses than the total number of stars that are estimated to exist in the universe? That’s absolutely incredible and mind bending. Especially considering the number of stars in and of itself is impossible to truly grasp.
2:25 Viruses are not parasites parasitism is a type of symbiosis in order to considered a symbiote you have to be alive viruses are not alive therefore they cannot be parasites personally I think they should be considered alive but that is not a choice I can make
Prasitism and symbiosis aren’t the same thing. Symbiosis is where a host and other aid each other and both are benefiting. In parasitism one is benefiting and one is at a detriment.
Your videos are usually incredible and accurate, which makes me wonder why you keep talking about humans as if the placenta happened one million years ago and not about mammals. It really makes it sound like all of evolution was geared towards human evolution.
That is a good point. Humans are not special, we are not central to nature, life or evolution. I think they give human examples to help people with less scientific knowledge better understand the content.
Interesting that some viruses can remain in immune protected [called "immune privilege"] body parts such the eyes and testes even after the person recovers from the disease. I wonder if this affected the retrovirus exposure and lead to them being inserted into our germ cells [sperm etc.] more easily? Did immune privilege lead to the placenta?
I had it and my compromised immune system fought it off while pregnant. My doctor seemed surprised even while he quoted how it’s actually very possible to.
A scientific video about evolution should not make misleading statements like "evolution is a machine of randomness." This misconception is one of the reasons that creationists withhold basic knowledge about our existence from children and have created a war about evolution. Mutations occur randomly, usually, and everything that happens after that is a "machine" of meaningful, non-random selection.
Stephanie works there as an editor and wrote some of the episodes there. She got inspired and help to start her own channel where she does the writing and editing. She has a degree in science communication and one in biology.
Mam, I want to ask a question, that parasites are the ones who live in the host''s body and get nutrition from there, so can we say that a foetus, who also derives its Nutrition from mothers body, that foetus is also a parasite, if yes, then it won't be wrong to say that we all were parasites before our birth. Looking forward for your answer.
I'm not a biologist, but I would say pretty conclusively that a fetus is not a parasite of its mother. Parasites reduce the host's fitness (in the Darwinian sense), and producing offspring is pretty much the opposite of reducing fitness. The process of the mother passing on her genes to her offspring requires a fetus--and in fact, the fetus _is_ her offspring.
6:25 What is this song called? Who made it? Where is it on artlist? Can you list your songs at the end of the video as credits? I'd like to listent to them on my iPod.
Ok this video made me feel a bit better after I found out I had HPV . One thought that comforts me but may not be scientifically accurate : if the virus kills me then it also dies with me ; so it won’t .
Great video but I have a bone to pick here. You are correct that evolution doesn't have a plan. But then a wrong conclusion is drawn that evolution makes do with what it has. This is wrong because evolution is not an alive entity. It is an emergent process. As such, referring to evolution as an entity is just anthropomorphization
How is it possible to recognize a gene as it is a viral fossil. The DNA sequences are just a compilation of A,T,C,G and they all look the same ? Is there a specific think about virus sequences that allows this observation ?
Most of our DNA is called "garbage DNA" meaning it is never used by the body to produce proteins. How did they get there? We know some viruses get inside our DNA, so logically that has to be at least part of the way we accumulated all that "garbage DNA".
Because it matches viral DNA at some points, more than you'd reasonably expect. The wiki-piece on it has more scientific links too. en.wikipedia.org/wiki/Endogenous_retrovirus#Human_endogenous_retroviruses
There is no evidence to conclude randomness. Merely purposefulness of prior events you simply assume are perchance rather that relative and triumphant.
They are deterministic outcomes and cannot be classed as evolution 'being like so .. totally random'. Making good out of bad is a beneficial trait to have when successful is measured by survival alone.
Its really cool brother i also learned today something other what I use to see in these information videos is the repetition of the some fact either I know or something which my mind just created a while ago and that video validates it but this time I also got amazed
6:39 Thank you for calling the organism, a "baby." It gave me hope..... It is a lovely and informative video, it just struck me - that word, even more than the virus nor its connection to our human evolution - which is a fantastic theory in itself.... Thank you.... Just thank you.

Can you list your songs at the end of the video as credits? I'd like to listent to them on my iPod.
When the Sunrise (instrumental version) by Sivan Talmor
@@dyl_the_editor Thanks Dylan!
Very nice video. Love the vibes.
Excellent video. Very interesting, informative and worthwhile video. I look forward to your forthcoming videos.
Ok this video made me feel a bit better after I found out I had HPV . One thought that comforts me but may not be scientifically accurate : if the virus kills me then it also dies with me ; so it won’t .
Quality content bestowed upon us once again
Make a video about mycologyyyyy fungiiii mushroooms pleaseee
Great video but I have a bone to pick here. You are correct that evolution doesn't have a plan. But then a wrong conclusion is drawn that evolution makes do with what it has. This is wrong because evolution is not an alive entity. It is an emergent process. As such, referring to evolution as an entity is just anthropomorphization
Very cool topic and veey well laid out video with useful animations
Hmm, I don't know. How sure can one be that this turn of events was beneficial for humanity? Great video and awesome visuals anyway!
How is it possible to recognize a gene as it is a viral fossil. The DNA sequences are just a compilation of A,T,C,G and they all look the same ? Is there a specific think about virus sequences that allows this observation ?
Viral genome in humans is like Internet Explorer in Windows 10.
Thank you soo much for sharing such information. Keep sharing us
I was quite disappointed... nobody became like Alex Mercer
lol tha game is so underrated
Beautiful voice, informative content.
Some brain mechanics are thought to be leftover of viruses aswell
Yep! They think some of our ability to store memories is linked with viruses.
How do we know it's viral? Like, what's different about it, compared to normal DNA we have?
Most of our DNA is called "garbage DNA" meaning it is never used by the body to produce proteins. How did they get there? We know some viruses get inside our DNA, so logically that has to be at least part of the way we accumulated all that "garbage DNA".
Because it matches viral DNA at some points, more than you'd reasonably expect. The wiki-piece on it has more scientific links too.

Great study 🙏🙏👏👏
visible universe
Mind blowing
Wowww, very precious information, thank you so much.
There is no evidence to conclude randomness. Merely purposefulness of prior events you simply assume are perchance rather that relative and triumphant.
They are deterministic outcomes and cannot be classed as evolution 'being like so .. totally random'. Making good out of bad is a beneficial trait to have when successful is measured by survival alone.
Beautiful, thank you
me, watching this while infected with a virus
One of the few exceptionality insightful science videos ob the net!
Your channel is the best
Such an beautiful voice
Thx 4 sharing
Looks as tho we’ve had Syncytin-1in our lineage for about 25 million years.

Absolutely FASCINATING!!!
Its really cool brother i also learned today something other what I use to see in these information videos is the repetition of the some fact either I know or something which my mind just created a while ago and that video validates it but this time I also got amazed
Imagine a world without viruses
And suddenly a virus appears
Amazing video
6:39 Thank you for calling the organism, a "baby." It gave me hope.....
It is a lovely and informative video, it just struck me - that word, even more than the virus nor its connection to our human evolution - which is a fantastic theory in itself....
Thank you.... Just thank you.
Make a vid on stiches
How can she that the virus population is more than the number of stars,as if she saw the end of the universe....
The known universe is a thing. When most of us talk in such a way, we mostly mean the known universe, not the entire thing.
This is fascinating!
What benefits wil come to virus by making placental proteins?
Is there any other positive change we know about with viruses other than this one mutation?
The placental ‘viruses’ sound a lot like exosomes…
Didnt everyone learn this in grade 10 or 11?
Amazing content
Damn nature yo crazy
1:35 8% of our DNA is viral. The other 92% are memes.
8% viral memes, 92% forced memes.
Okay NOW I think I understand the platypus!
What about other animals. I presume a lot of mammals have these genes as well?
Wow it’s a great video
I don’t know if it’s all that random but very interesting nonetheless
