The origin of the Prehumans and the reason of their new standing posture
Common ancestors (Hominidae) to Prehumans (Homininae) and Prechimpanzees (Paninae) are supposed to have lived in tropical Africa, in a forest environment, 10 million years ago. Their descendants, because of the settlement of the Antarctic sheet (for cosmic reasons), had then to deal with two sorts of environments instead of the previous forest one: a covered one (forest again) and a less covered one (open forest); this was the reason for the double descent of the aforementioned common ancestors, Prechimps in the covered environment and Prehumans in the less covered one. The birth of Antarctica has been explained by astrophysicists, the opening of the landscape by biochemists (proportions of carbon isotopes in the enamel of vertebrate teeth before and after 10 million years). Homininae adapted to this very new open environment thanks to an erect posture. Prehumans therefore stood tall, walked but still climbed, ate fruits in the trees and roots on and in the ground.
