Human Origins Theory Tested By Recent Findings

annamadrigal writes "The BBC news is reporting on findings presented in Nature which suggest that Homo Erectus and H. Habilis were in fact sister species which co-existed. This challenges the view that the upright humans evolved from the tool users."

Other great apes were evolved for primarily eating fruit (orangutang), veggies (gorillas), or a more mixed diet (chimps). I'd say that human ancestors didn't take to the flatlands all that great but were actually well adapted to rivers and for the style of fishing known as noodling. (Paddle-like foot shape, thinned out body hair, improved hand dexterity, downturned nose, these seem better adapted for mucking in water than walking around on some grassland.) Afterall, in comparison to the great apes we're related to, humans are the only ones that can swim worth a damn. Crocodiles as a competing apex preditor would be a lot more predictable for pre-tool hominid primates than any lion, jaguar, or hyena. (Easy enough to get out of the water when crocs are around, but good luck outrunning one of those large cats.) Also there's likely more protein to be had from fish than any small grassland type creature that could be caught until toolmaking became more mainstream.

Now if only an actual anthropologist would pick up on that idea...
