I saw a doco of this chimp named oliver that was captured in wild in africa.
He walked upright, had a different scent, smaller skull, ears pointed etc. When he was interacting with other chimps they rejected him because he prefered to walk upright, shoulders back. Normal chimps can walk upright when trying but because of thier hips, their grassilius and quadracept muscles get very tired and feel comfurtable on all fours.
Long story short.... THis chimp was thought to be a human-chimp hybrid a humanzee(gross i know)
but later DNA test's found that he was completely chimp.
Some scientist think he is sub-species of chimpanzee others say he's a anomoly or a dawn of a new chimp species?
Shame no other chimps like him have been found so i think they've probably been wiped out.
What a shame. He is apparently still alive and still preferes to walk upright, shoulders back.
Anyone got anymore info?
