The numbers keep getting bigger:
New dating techniques suggest the remains of so-called Peking Man — a batch of Homo erectus fossils found in the 1920s — are 200,000 years older than previously calculated.
What’s important about that date, about 770,000 years ago, is that this was a glacial period on Earth, and Peking Man was found in far northern China.
So follow this logically:
First, if Homo erectus existed both in Africa and outside of Africa, how did both populations end up being Homo sapiens?
Second, if nearly a million years ago humans were out of Africa, there’s a whole hidden pre-neolithic history that none of us know yet. And that’s why the dates keep changing.
