Is This the Last Common Ancestor of African Apes and Humans? | Nakalipithecus
Ғылым және технология
Anyone who has heard even a small amount about the evolutionary history of our species has likely also heard something about the Out of Africa theory - whether first-hand through direct scientific terminology, or second-hand through its application in popular media. In short, the theory is everything it says on the tin, but I won’t leave you hanging. The Out of Africa theory - which is a true theory; it’s not just a fancy title applied to an hypothesis - is the comprehensive model that describes the geographic and evolutionary origin of archaic and modern humans from early modern humans and archaic Homo species out of Africa and across the world.

3:09 That seems to be a running theme with great ape fossils. Then again, that’s what happens when you live in tropical forests, which are notoriously for how poorly they preserve fossils.
We carry ourselves, through our DNA and MRNA at least 15 now extinct hominids, including neanderthals, denisovans, homohabilis and homonaladi. And it's important to remember the great African rift Valley discoveries of hominids were largely based on fragments of teeth or part of a skull. Modern paleoarchaeology techniques will be partly reinvestigation of old fragments with newer, better preserved artifacts, and modern tech that will astound us
Are the fossils found in Eurasia closer to orangutans than gorillas? It seems likely that orangutan ancestors would have split off really early and lived in Eurasia before eventually making their way down to Indonesia.
0:51 It should be said that some of these numbers are out of date. Im pretty sure the lower limit for humans in Australia is up to like 60k years at this point, and its getting longer for humans in the Americas too

I could be wrong, but didn't they recently discover a much older jaw bone and teeth from an human ancestor than the ones from Ethopia/Africa around the Eastern Mediterranean basin?

There were so many humans and apes etc walking around tht it's impossible to say a link or split or where humans started .it's all bullshit apes we're everywhere around the world and they bred into humans somehow
I'm also confused on why you think that apes must have evolved in Africa, when the oldest divergent branches (gibbons and orangutans) live in SE Asia rather, which thus holds the present greatest basal diversity (by comparison Africa only has one branch). Sure: there are some fossils from the prolific Great Rift (a very peculiar orography that makes access to ancient layers much easier than anywhere else on Earth) but the fossils could mean anything: including diverse migration from Asia in the days Africa was much more covered in trees (and thus available for apes and monkeys to migrate in both directions: to and from Asia). Kenyapithecus could still be basal only to African great apes (hard to say from just a partial jaw), while proconsul could be anything: from a direct precursor of African great apes (us included) to a side branch that did not survive to leave any legacy.

Those are the downsides to archaeology and dna. They aren’t necessarily great at explaining the direction of migration. Sometimes they are but in many cases all they can tell us is yes there was a link and yes there were migrations around this time or that time but maybe less clear as to actually how.

@@ryanmassey586 - This is all paleontology but you're right that fragmentary knowledge is definitely confusing about "direction": we get the dots, some dots, but we can hardly join them. If we'd actually have paleogenetics, then we could at least get a proper phylogeny.

Lori's brother Simon is obviously the transitional species between gorillas and humans.
Now thats the kind of science i EDGE to
You don't need more baby steps, you need more baby reps.
Considering the date of c. 9.5 Ma ago, I'd go for Nakalipithecus not being a common ancestor of African apes but rather of gorilla. In my understanding the Pan-Homo split cannot be more recent than 8 Ma ago (and is maybe much older, 10 or 12 Ma make good sense, some have given max. ranges of even 17 Ma). This is largely because Sahelanthropus tchadiensis (Toumaï) is absolutely clearly already in our line and not anymore in that leading to chimps and bonobos (unmistakably bipedal but also with some human-like brain features in spite of the brain being small) and is from c. 7 Ma ago (thus the Pan-Homo split must be older). On the other hand there's some genetic evidence (a full chromosome's introgression) for the Pan branch (but not our branch) having hybridized with gorillas or rather proto-gorillas like could be this Nakalipithecus, so maybe it is partly ancestral to chimps and bonobos as well.
Gap is still huge. Still waiting on those links, starting to lose faith that they’re coming given we should be finding more recent stuff.
Cool
Also need to consider viral agents.

7:36 But bipedalism send to be the ancient vondition if great apes. All apes have descended from ancestirs similar to the gibbon species that they have moved and lived on trees, but between trees they used a bipedal walking. Knuckle walking has evolved in gorilla and pan independently later. They can be considered more evolved that way if you would like. Or fo you disagree with the papers in question? If so, why?
