Walking with Cavemen

00:00:05 First, our ancestors walked upright.

00:01:25 These people are heidelbergensis

00:02:43 These men and women have brains almost as big as ours

00:03:50 and yet, for these people, it's unthinkable not to.

00:04:46 But these people can't. They're just too literal-minded.

00:05:47 Heidelbergensis are spread throughout Europe and Africa.

00:10:30 ...and they've evolved a trait

00:11:40 The weather has also changed their minds.

00:13:29 They've walked for three days...

00:14:33 and an opportunity too good to be missed.

00:23:05 With it, the tiny population of humans in Africa can hold on

00:24:30 to share their new ideas with each other

00:25:22 from every other creature in the whole history of life.

00:26:34 Her kind has been one of the most successful species in human history
