Why Are We The Only Humans Left? | PBS Science Video

August 8, 2017

In part 2 of this special series on human ancestry, we ask why we are the only surviving branch on the human evolutionary tree. Just 50,000-100,000 years ago, Earth was home to three or four separate human species, including our most famous cousins: the Neanderthals. New research has shown that Neanderthals were not the brutish, unintelligent cavemen that cartoons make them out to be. They were creative, smart, social, and perhaps even had complex language. So why did they go extinct as soon as Homo sapiens moved into their territory? Does any trace of them live on today? Why don’t we have Neanderthal neighbors?

This part and the next two parts of the 4-part Human Ancestors series will run consecutively, 4 days apart.

This is an installment of the PBS – It’s OK to be Smart series. If no film or link appears in this email, go to the blog to view it by clicking on the blog title above. If the film stops & starts in an annoying manner, press pause (lower left double bars ||) to let it buffer and get ahead of you.  [Chuck Almdale]
