Question

What environmental changes were taking place in Africa during the time that bipedalism developed and the hominin line diverged? How might these changes have favored bipedalism?

Answer 1

In early period there is a potential interaction between human evolution and climate changes.The response of the species to environmental changes is quite unique.In Africa vegetation patterns are altered along with the modification of physical environment and it affect the remainder of ecological community.each species differed by adaption to climatic conditions.eg.,neanderthals with shorter limb bones and fore arms.trees during that period induce cooling and dry the climatic regime over Africa.grass lands were expanded and conratracted in past 5Ma.These changes helps bipedalism to change their species evlotion at each and every decade.the species also adapt themselves for the environmental changes.
