Human beings
Hundreds of millions of years
:bugs-no:
The most recent common ancestor for humanity has been estimated at 1400 BC, and the point where we have no uncommon ancestors at 5300 BC. The only exceptions would be tiny populations of fully isolated peoples such as the North Sentinelese Islanders.
What does uncommon ancestor mean here? In 5300 BC there were no individuals that some modern humans but not all modern humans descend from?
I thought we left Africa around 70k years ago at the latest due to the Toba explosion?
Seperately? Didn’t we kill and interbreed with Neanderthals and shit?
Also didn’t humans only leave Africa less than 100 000 years ago? And our genome is no where as flexible as other animals, if you want to put it that way.
Modern humans left Africa something like 100,000 years ago, but predecessor species like Homo heidelbergensis (found in Spain) and Homo erectus (found in Indonesia) had left Africa hundreds of thousands of years before that. One of the things that broke my brain in college was realizing all the human off-shoot species also had boats and had already gone across nearly the whole world before modern humans showed up.

The Homo genus proliferated around the world several times over, with different species and subspecies of humanoid dating back tens of millions of years.
Homo Erectus - the progenitors of modern Homo Sapeins Sapeins, and a number of other close relatives - demonstrate a fossil record as far away as the Philippines. The “Flores Man” was a genuine subspecies living out on the island of Flores, Indonesia until extinction around 50,000 years ago.
Africa happened to be a font of human and near-human relations. It served as a veritable Garden of Eden for genetic diversification. But humanity and its off-shoots were not confined there over its millions of years of evolution.
The human genome is incredibly homogeneous when the widespread distribution throughout the world is considered. This is due to a fairly severe genetic bottleneck at the last ice age as well as the fact that we are constantly moving about and fucking everything that moves.
I had a professor once who said that if aliens came to earth and examined humans they would think we all originated from a population of clones because we are all so alike, I don’t know how true that is, but I like the anecdote.
Pre-historic humans were split into different sub-species but they all died out or we crossbred with them. The last living species of human other than us were the neanderthals.
i’m always amazed at how widespread ancient humans were too. It’s a complete myth that humans evolved in separate environments, because ancient humans were everywhere and constantly moving. Homo erectus was from where Indonesia is now. Humanity went back to Africa multiple times, which is where we finally evolved into modern homo sapiens. There were incredibly long trade routes going from northeast europe all the way to southeast asia. Neanderthals had some kind of burial religion that was practiced all the way from Spain to central Russia.
[Verse 1]
When I wake up, well, I know I’m gonna be
I’m gonna be the one who watches out for predators for you
When I go out, yeah, I know I’m gonna be
I’m gonna be the one who brings back all the food
If I get drunk, well, I know I’m gonna be
I’m gonna be the first the who figured out it was fermented fruit
And if I haver, yeah, I know I’m gonna be
I’m gonna be the one who’s haverin’ about my fire making skills.
Idr what variant it was but apparently the most recent one was actually the version that lived in caves in China, and it was almost close enough in the timeline for written history. Low-key wish it was though I want those deets
Does her textbook show us riding Tyrannosaurs into battle?
