Been watching a lot of YouTube lately...maybe a bit too much. In any
event, became fascinated to learn about mitochondrial Eve, a female all
current living humans are descended from. She is hypothesized to have lived
200,000 years ago in East Africa and we know about her because certain
genetic traits are only passed on by females. (In effect, a point of mitochondrial
convergence that can be dated...)
There is also a genetic Adam, perhaps older than Eve, and from West Africa.
Thus the human couple, only they never met.
Still the numbers are impressive. We were hominids(monkey-like) 6 million
years ago, Homos 2 million, Homo Sapiens 200,000. Homos were the first to
leave Africa, and use tools. Homo Sapiens, and some would restrict this to
Homo Sapiens Sapiens, are anatomically similar to us. All living humans are sapiens.
I asked Chat how many generations of Homo Sapiens there have been; didn't get an
answer but 200,000 years at 20 years for one generation gives 10,000...
That's a lot of diapers!!
HAPPY VALENTINE'S DAY TO ALL!
