With this theory, scientists speculate kissing was established among human ape ancestors as they started spending considerable time on the ground away from trees, which increased the risk of parasitic infestation. This could have come "only after" ancient climate change shifted ecology from forested ...
Hypotheses concerning the origins of modern humans have been intensively debated, and two competing models, the recent “Out-of-Africa” and R
