They use similar methods to analyze DNA left at a crime scene to predict what the perpetrator looked like. It doesn't seem very exact, but it at least narrows down some factors like coloration
Probably just look like a modern human. This is still way too early of a science to do more than paint with a broad brush. They're looking to see general characteristics not enough for a police lineup.
Epigenetics can be used to tell how prone someone is to certain types of cancer, and what is their prognosis if the disease occurs. It can quite accurately pinpoint someones age as well. Epigenome contains information if you or your direct ancestors went through severe malnutrition. These are just some examples I recall off the top of my head.
What I’m more interested than anything is evidence of non homo sapien agriculture and/or evidence of sophisticated culture verging on civilization. I think it’s plausible because agriculture does not leave very significant traces behind and in the early stages one disaster could wipe a small offshoot of burgeoning civilization off the map. We know agriculture is at least 14,000 years old but what if it was 40,000 we know from the fossil record there was enough excess grain to feed dogs enough to change them physiologically which is extremely interesting. Up vote to get PBS to do an episode on non homo sapien cultures!!!!

I participated in the Genographic Project 1.0 and 2.0. The 2.0 would estimate the amount of Neanderthal and Denisovan DNA, I had unusually high of both: 3.5% Neanderthal and 5.5% Denisovan.
that sounds really cool, recently an indigineous ethnic group from the Philippines called the Aeta had 6% Denisovan dna which might suggest that Denisovans might have survived much longer than neanderthals maybe?
@@cerridianempire1653 Can't interpret that from a %, population size of both groups in the area may have lead to greater intermixing between homo and deni, west Africans have up to 19% dna from an unidentified hominin but no remains have been identified, while a high % of their dna would suggest they'd been around only recently based on that theory and we'd likely have some physical evidence available.
@@speurtighearnamacterik8230 pretty improbable, at least not particularly commonly. We're pretty hard-wired against cannibalism, and these other human (sub?-)species were ckose enough to us that that should trigger. We may have had some hand in their demise, but hunting them for food? probably not. It's already pretty rare for us to do that with apes today, but with others in the Homo genus or even the Homo Sapiens species? (some argue Neanderthals and Denisovans are just a subspecies)
@@nerdyspinosaurid Neither of them are subspecies. Neanderthals and Denisovans form a sister group to the Homo sapiens, and it’s very well known that the hybrids that Sapiens and Neanderthals produced were mostly infertile, only being able to reproduce with Homo sapiens time to time. They were genetically distinct enough to be considered separate species.

@@swimdownx6365 I don't think so... just making it more complex on the molecular level, as there should be a specific structure on the DNA to be methylated, the proteins doing the mathylation are also coded in the DNA (i.e. more efficient version of the protein will be able to do more methylations and thus the genome would be more regulated) etc. There was a paper some 3 years ago showing how both gene sequence and its regulatory sequences work together to give more phenotypes with more intersteps. Methylation also works for switching between two versions of phenotype be it sommer and winter generation of some insect species, or effeciency of metabolism in human based on the fact, if their grandmothers were hungry in their youth, so all this should be taken as one feature.

I wonder if there's a particular reason Denisovan fossils are so rare. Do you suppose it's environmental, or is it possible that they had some kind of funerary practices that tended to destroy the body?
Probably the environment, fossilised remains are very rare. It takes like a million things to get something to fossilise. The amount of fossils that have discovered so far from the human line are so few. That they could all fit in a cardboard apple box.

"Wider fingertips." "Wider skulls." * looks at my weirdly square fingertips and my lucky hat, which is custom-made because regular hats don't fit my head * Welp. That's one to add to the "reasons to get a DNA test someday" list.
To answer the question - it's possibly because of their range. There's a lot more acidic soils in the north out by Russia/Siberia (things like peat bogs and variable permafrost) and since there's also denisova type dna in places like Indonesia - bones don't do well in hot soggy environments.
Even though we don't have concrete answers and probably won't for a long time/ever, it's just so cool that we can make these predictions and guesses to start with. Genomics is such an interesting topic!
It's very interesting to learn there were other human species, and sad we're the only ones to survive. It makes me very curious how life would've been like if they were still living amongst us
I think more fun time would have been if we were living amaong other human species. All hunters and gatherers no worry of paying bills. And imagine hanging out maybe even dating a person of a different human species.
Naturally? I don't think so, except perhaps by settling the galaxy by sleeper ships, creating an extreme barrier against cross-mingling. Culturally: I guess it would be possible, but ethically highly problematic to create another human species mainstream homo sapiens can’t interbred with naturally with. Though I guess at that point the whole “separate species” things becomes irrelevant, as a hypothetical homo sapiens and homo sapiens aquaticus who fall in love would have the technological means to create a viable offspring.
Yeah, it'd require hundreds of thousands of years with no interbreeding for two populations to accumulate enough unique genetic differences to be considered different enough to be a new species/subspecies, and much longer for hybridizations to become unviable. Consider that Neanderthals likely diverged from us and began evolving independently >600,000 years ago, maybe as far back as 800,000 years ago, and interbreeding only occurred between 65,000-47,000 years ago, as far as we can tell.
Seems anti-feminist to reduce a woman in the workplace to her appearance. Comments like that could be unwelcome as a science presenter doesn’t deserve to be judged in that way. Whatever happened to sisterhood. Maybe you forgot PBS is a business and not in the home.
This had me wondering: we have genetic evidence of Human and Neanderthal, uh... intermingling. Do we have evidence of the direct evidence of such couplings? Would they be considering the same species of one their parents? Or classified as something else entirely?
Speciation is a complicated subject, especially in paleontology. Most definitions of species include the ability to reproduce as a determining factor. Because of this there is some debate about whether or not neanderthals and homo sapiens we're even completely different species or just a different subspecies.
That feeling when you finally realise that you've been pronouncing "Denisovan" wrong for years, and no-one corrected you... then again, "Denny's Sew Van" would be a catchy band name... ;-)
I am absolutely fascinated by the Denisovans, interesting to learn how science has arrived at its speculations of what they might have looked like considering how little physical evidence is even available
Humans have inherited some genes due to interspecies hybridization, humans from South Asia, Oceania and Amerindians have high amounts of their genes, a 2020 study found a Denisovan gene related to lip thickness in Amerindian populations
As Europeans carry the Neanderthal genes and also some of its physical manifestations, many Southeast Asians and Oceania carry the Denisovan genes so it's probably not bad to assume they also carry those physical manifestations.
Biotechnologist here. I'm curious to see if the other epigenenitic regulation factors were counted into the prediction (i.e: acetylation). Becauss in our genome, expression is regulated not only by methylation. PBS EONS can you guys make an update video on the spinosaurus tail? This cool "amphibian" Dino needs a justice for its tail hahaha.
I love the episodes on human evolution. The recent podcast about the South African caves was a treasure Edit: lol you shouted out the podcast episode at the end
Their is NO relations nor connections of the hybridized cromagnan NEANDERTHALS human EXISTENCE to the carbonated divine PRIMORDIAL BEINGS of the planet.
I heard once that Australian aboriginals had more Denisovan dna than any other modern human. If true, it makes it easier to imagine Denisovans with the dark skin trait mentioned. I always pictured Denisovans as looking like a mix of Neanderthals and Papua New Guinea & Australian aboriginal people since I heard that.
This is my favorite topic. And Michelle presents it so well. I just have to say, though, Michelle, you look amazing! I love your hair and that dress is gorgeous!
Hello EONS! I'm sorry, I'm not too tech savvy, but I was trying to find a way to message you guys. I would absolutely love it if you could delve into the history of the Haast eagle, or the Harpagornis, from New Zealand. It was the largest flying predatory avian in modern history. There are even pelvic bones from the Moa, which were basically, ostriches on steroids. which were penetrated by Haast eagle claws. There is such a case in Auckland museum. I would love to hear your take on that, and how humans caused the extinction. Just imagine how majestic it would be if they were still flying around today. A raptor the size of a small Cessna plane!!!! Incredible. Anyway, hope you guys see this. Thanks for all you do!
Honestly, I’d love to hear more about the hominid species that was found in the Rising Star caves. We have more than enough bones, whole and fragmented, to get a pretty accurate morphology.
I would love to see a video on the Baldwin effect. It sounds like a way that natural selection can produce the appearance of Lamarckism and creativity after a sudden change in environmental pressures, but I don't fully understand it.
my six year old really likes your podcast, do you think you will transfer some of these videos over to the podcast? I know he would love to listen to some of theses.
I'm kind of curious, how much of the Denisovan genome is present in the human genome, as well as what percent of humanity has some of their genes and how much ?
@@speurtighearnamacterik8230 Neanderthal was mainly shaped by harsh environnement too, thats why it looked so different despite having common ancester few yers ago. I agree about the number part tho, Sapiens were in larger amount. Also climate started to change and Europe was de-icing...meaning the harsh environnement Neanderthal specialized on was slowly disapearing...huge animals, cold climate...all of that vanished. It changed for more agile and faster prey, for wich Sapiens "endurance hunting" strategy develloped in Africa was wayyyy better. Final nail to the coffin would be that Neanderthal lived in very small groups, rarely stumbing across each other...so any technological novelety wouldn't spray easely or even at all among them. While Sapiens kept improving the way they craft weapons (stone fragmentation), Neanderthal had the same way of doing it for ALL THEIR REIGN!! And it was the same manner to do as their common ancestor with Sapiens...that's something right? So Neanderthal vanished, not because he was "less evolved" than Sapiens...in fact it's the contrary. He was way too specialist and couldn't adapt quickly enough to the lost of his niche. On the other hand Sapiens was a generalist, and still is. That's also why he/we succeded so much. generaliusts always win in the long term
Idea for show - What kinds of forces create what kinds of features - i.e. What caused the fjords? What's the difference between different mountain chains?
Was wondering if paleogenomics can be used in modern day? Ie forensics to determine what a suspect or victim looks like if very little is left eg natural disaster, fire?
There are cases where DNA at crime scenes is used to predict what the suspect may look like. I saw a true crime documentary a few weeks ago where they predicted what I suspect might look like, and they were able to find somebody who looked a lot like the prediction.
Wouldn’t comparing individuals with the most Denisovan DNA to modern humans with very little or no Denisovan DNA give scientists clues about what Denisovans looked like?
Indigenous Australians, certain ethnic groups in the Philippines, and Papua New Guineans have the highest levels of Denisovan DNA. So it’s suspected that Denisovans may have looked similar to those peoples

I think more fun time would have been if we were living amaong other human species. All hunters and gatherers no worry of paying bills.
And imagine hanging out maybe even dating a person of a different human species.
I'm kind of scared to know how our close relatives died out so long ago, and so completely, judging by how we scarcely found any fossil evidence
Excellent video as always! You should do a video on the Tanis site!
I've been so excited waiting for this one!!!
Fascinating.
I wonder if any more human species or subspecies may arise in the future.
Naturally? I don't think so, except perhaps by settling the galaxy by sleeper ships, creating an extreme barrier against cross-mingling.
Culturally: I guess it would be possible, but ethically highly problematic to create another human species mainstream homo sapiens can’t interbred with naturally with. Though I guess at that point the whole “separate species” things becomes irrelevant, as a hypothetical homo sapiens and homo sapiens aquaticus who fall in love would have the technological means to create a viable offspring.
Yeah, it'd require hundreds of thousands of years with no interbreeding for two populations to accumulate enough unique genetic differences to be considered different enough to be a new species/subspecies, and much longer for hybridizations to become unviable. Consider that Neanderthals likely diverged from us and began evolving independently >600,000 years ago, maybe as far back as 800,000 years ago, and interbreeding only occurred between 65,000-47,000 years ago, as far as we can tell.
Man, I really wish I would have pursued those genetics classes in High School. It was interesting finding out the genome of fur colors in Rabbits.
PBS Eons bringing us the knowledge!
I find the topic fascinating. Especially because all of these new species could - and did - interbreed with homo sapiens.
I don't have any sound and it's killing me, I've been DYING for another human episode like this
You can use subtitles (cc) 🙂
Excellent video as always, and stellar presentation!
I love this channel so damn much
They say "never judge a book by it's cover" but this is more like "never judge a cover by it's book"
Can I just say that both the haircut and outfit for the host in this episode are absolutely amazing
Seems anti-feminist to reduce a woman in the workplace to her appearance. Comments like that could be unwelcome as a science presenter doesn’t deserve to be judged in that way. Whatever happened to sisterhood. Maybe you forgot PBS is a business and not in the home.
Girllllllll. I was seriously trying to find a non-gross way to say how smoking hot she is lol. It’s wild, like…that lip colour? Sheeeesh 🔥🥵😍
I have to say this episode is a vast improvement in presentation by this host. Nicely done! 👍
I love how this is what inspired the Croods movie. Very nice narration
This had me wondering: we have genetic evidence of Human and Neanderthal, uh... intermingling. Do we have evidence of the direct evidence of such couplings? Would they be considering the same species of one their parents? Or classified as something else entirely?
I've been to Manchester, I'm pretty sure I've seen the results of such a union...
Speciation is a complicated subject, especially in paleontology. Most definitions of species include the ability to reproduce as a determining factor. Because of this there is some debate about whether or not neanderthals and homo sapiens we're even completely different species or just a different subspecies.
@@dereksmalls6238 nice one kidda 😂
So, one of his 16 great-great-grandparents either was a Neanderthal, or a Neanderthal-human hybrid.
@@dereksmalls6238 💀
this is such a cool discovery and a method both!
Love this type of video. Thank you!
That feeling when you finally realise that you've been pronouncing "Denisovan" wrong for years, and no-one corrected you... then again, "Denny's Sew Van" would be a catchy band name... ;-)
I am absolutely fascinated by the Denisovans, interesting to learn how science has arrived at its speculations of what they might have looked like considering how little physical evidence is even available
Humans have inherited some genes due to interspecies hybridization, humans from South Asia, Oceania and Amerindians have high amounts of their genes, a 2020 study found a Denisovan gene related to lip thickness in Amerindian populations
@@eltecnico9541 thanks, this is highly interesting!
Y'ALL I HAVEN'T WATCHED THIS YET BUT ANCIENT HUMANS IS MY FAVORITE TOPIC ON THIS CHANNEL WOOOOOOO
If you are wondering about the nice song, it is Honey by Daniel Roe
As Europeans carry the Neanderthal genes and also some of its physical manifestations, many Southeast Asians and Oceania carry the Denisovan genes so it's probably not bad to assume they also carry those physical manifestations.
Biotechnologist here. I'm curious to see if the other epigenenitic regulation factors were counted into the prediction (i.e: acetylation). Becauss in our genome, expression is regulated not only by methylation.
PBS EONS can you guys make an update video on the spinosaurus tail? This cool "amphibian" Dino needs a justice for its tail hahaha.
lovely video.. i was lost in the story and thought i was in denisoven era through time travel..
I love the episodes on human evolution. The recent podcast about the South African caves was a treasure
Edit: lol you shouted out the podcast episode at the end
Native Austrians have more Denisovan genes
Michelle you look incredible! I love your hair and outfit here 😍 serving looks AND science, we love to see it! ❤️
Last time I was this early to a video, the Cambrian explosion was happening
Interesting. I thought that Denisovans were closer related to Homo sapiens than to Neanderthals.
Their is NO relations nor connections of the hybridized cromagnan NEANDERTHALS human EXISTENCE to the carbonated divine PRIMORDIAL BEINGS of the planet.
How am I just now finding this channel
I heard once that Australian aboriginals had more Denisovan dna than any other modern human. If true, it makes it easier to imagine Denisovans with the dark skin trait mentioned. I always pictured Denisovans as looking like a mix of Neanderthals and Papua New Guinea & Australian aboriginal people since I heard that.
The devious floating Denisovans
Fascinating video! Love this channel 😊❤
Cheers from the Pacific West Coast of Canada.
Fantastic episode! Learned a bunch!
awe the flower in her hair
This is my favorite topic. And Michelle presents it so well. I just have to say, though, Michelle, you look amazing! I love your hair and that dress is gorgeous!
Now let's clone a Denisovan and check how many of the predicted traits match! :D
Hello EONS! I'm sorry, I'm not too tech savvy, but I was trying to find a way to message you guys. I would absolutely love it if you could delve into the history of the Haast eagle, or the Harpagornis, from New Zealand. It was the largest flying predatory avian in modern history. There are even pelvic bones from the Moa, which were basically, ostriches on steroids. which were penetrated by Haast eagle claws. There is such a case in Auckland museum. I would love to hear your take on that, and how humans caused the extinction. Just imagine how majestic it would be if they were still flying around today. A raptor the size of a small Cessna plane!!!! Incredible. Anyway, hope you guys see this. Thanks for all you do!
Amazing intellect content and beauty, thank you.
I’m so happy I’m this early. I was so excited for a new episode to come out 😩🤚
How cool would it be to travel back in time and go back and visit and observe our human ancestors .... I need a time machine.
Get to work!!! ☑️
Ahhh, now I get what methylation does, thanks so much! That's so frickin cool!
*edit:* also I love your style, it's so varied ^~^
Honestly, I’d love to hear more about the hominid species that was found in the Rising Star caves. We have more than enough bones, whole and fragmented, to get a pretty accurate morphology.
Homo naledi
@@andybeans5790 that’s just the name. We should have an Eons episode about them
Was wondering how long that this would happen. Science is getting spooky! A good spooky but still spooky. Very impressive! Thanks Eons!
I would love to see a video on the Baldwin effect. It sounds like a way that natural selection can produce the appearance of Lamarckism and creativity after a sudden change in environmental pressures, but I don't fully understand it.
Great episode and omg that dress is fabulous!
my six year old really likes your podcast, do you think you will transfer some of these videos over to the podcast? I know he would love to listen to some of theses.
I love this narrator!
A video about auroch sounds interesting.
An entire podcast on Homo Naledi? Yes, please!
I'm kind of curious, how much of the Denisovan genome is present in the human genome, as well as what percent of humanity has some of their genes and how much ?
@@speurtighearnamacterik8230 nifty
@@speurtighearnamacterik8230 Neanderthal was mainly shaped by harsh environnement too, thats why it looked so different despite having common ancester few yers ago.
I agree about the number part tho, Sapiens were in larger amount.
Also climate started to change and Europe was de-icing...meaning the harsh environnement Neanderthal specialized on was slowly disapearing...huge animals, cold climate...all of that vanished. It changed for more agile and faster prey, for wich Sapiens "endurance hunting" strategy develloped in Africa was wayyyy better.
Final nail to the coffin would be that Neanderthal lived in very small groups, rarely stumbing across each other...so any technological novelety wouldn't spray easely or even at all among them. While Sapiens kept improving the way they craft weapons (stone fragmentation), Neanderthal had the same way of doing it for ALL THEIR REIGN!! And it was the same manner to do as their common ancestor with Sapiens...that's something right?
So Neanderthal vanished, not because he was "less evolved" than Sapiens...in fact it's the contrary. He was way too specialist and couldn't adapt quickly enough to the lost of his niche. On the other hand Sapiens was a generalist, and still is. That's also why he/we succeded so much. generaliusts always win in the long term
Idea for show - What kinds of forces create what kinds of features - i.e. What caused the fjords? What's the difference between different mountain chains?
Not that this is in any way the point of this fascinating science video, but... I'm loving Michelle's whole look in this ep! Girl you look amazing!
Was wondering if paleogenomics can be used in modern day? Ie forensics to determine what a suspect or victim looks like if very little is left eg natural disaster, fire?
There are cases where DNA at crime scenes is used to predict what the suspect may look like. I saw a true crime documentary a few weeks ago where they predicted what I suspect might look like, and they were able to find somebody who looked a lot like the prediction.
Yayyy I’m so excited for the video
Wouldn’t comparing individuals with the most Denisovan DNA to modern humans with very little or no Denisovan DNA give scientists clues about what Denisovans looked like?
Indigenous Australians, certain ethnic groups in the Philippines, and Papua New Guineans have the highest levels of Denisovan DNA. So it’s suspected that Denisovans may have looked similar to those peoples
