"A million years ago in Africa: the last of the ape-humans is on flight from the humans, who killed the rest of his clan. Alone, seeking others of his kind, he traverses steps, deserts and mountains until he reaches the coast. But there are already humans, too." via IMDB
Even though this is a pseudo-documentary the non-ape man parts are done expertly. There are quite a few scenes that you won't see in any nature documentary. The rip itself is not that great but it's the best out there until I order the VHS and attempt to do one myself. This needs a proper DVD release.
