Excerpts:
"We are all the children of Africa."
[Omo river in Ethiopia (far western side of the Omo) nearly 200,000 years, is our birthplace]
"The evidence suggests that the very first human-like creatures evolved in Africa over four million years ago.
They were much more ape-like than us,
A series of human species with gradually bigger brains came and went,
The most recent, and only surviving,
is our own species, Homo sapeins."
"For just a few thousand years, the Sahara, Sinai and Arabian deserts were lush and green.
So it looks like, 125,000 years ago, it would have been possible for our ancestors to have walked
through the Sahara and leave Africa to the northeast."
Part.2
"Professor Wu sees a clear line,
Homo erectus evolving into Upper Cave Man, becoming today's Chinese,
For him, these fossils prove that the Chinese come from a completely different branch of the human family."
"But I can see significant differences between the skulls,
The whole skull shape of Homo erectus is quite different from modern humans."
[conclusion: Chinese are not from different branch, they are also African, Geneticists proved]
Part.3
"Wo when Homo sapiens first arrived around 40,000 years ago,
Europe was already taken. (by Neanderthals)"
"Some scientists believe their descendants are still walking around today.
If our ancestor interbred with them, some of us could be part of Neanderthal."
"Researchers are now sequencing the Neanderthal genome,
using DNA from bones tens of thousands of years old (Neanderthal)
and comparing it with our own.
And so far there's no sign of any interbreeding.
Neanderthals really did die out."
[lack of vitamin D made the Europeans skin white]
