Walking with Cavemen

- Season 1

(2003)

As Africa transitions from forest to Savannah the world's first bipedal ape, australopithecus, evolved and flourished in the new environment.

At this stage several kinds of ape men populated Africa, each with its own unique adaptations. These species were doomed as the African continent grew increasingly arid, but a new human species well adapted to a hot dry climate emerged.

Homo agasta display the beginnings of families, tool making, team work and vocal communications. Some migrate out of Africa resulting in the evolution of additional human species in different parts of the world.

Robert Winston follows the final evolutionary push of mankind's ancestors, and discovers the key that makes us human.
