Ancient Human Ancestors: Walking in the Woods
Clip: Episode 3 | 3m 47s
"Ardi" changed our understanding of how our ancestors first started walking on two legs.
When did we start walking exclusively on two legs, and how did this transition take place? Neil Shubin pays a visit to Tim White and Owen Lovejoy, two anthropologists working together to understand "Ardi," a 4.4-million-year-old fossil that sheds light on our transition to bipedalism.
