The NOVA series âBecoming Humanâ describes the discoveries ofseveral different fossilized remains found in Africa of humanancestors. These discoveries are changing the way scientists thinkabout the evolution of our species from ape like ancestors. It isbecoming clear that the earth and specifically the African riftvalley, a few million years ago, was going through severe climatechanges. In part II there is new evidence about when humans becameessentially hairless and the selective advantage for thischange.
For your post, choose one of the discoveries above, (bipedalism,or brain size, or hairlessness, or relationshipswith neanderthals) and describe the selective pressures found inthe environment that might have contributed to its development. Dosome additional research on the web to determine if the viewspresented in this NOVA series regarding the trait of your choiceare supported by other scientists or do other scientists disagree.Moreover, can you see any parallels or lessons that relate to theclimate changes we see right now and the future of human evolution?Finally, comment on whether the research presented in this NOVAseries changed your view of the theory of evolution. Does itprovide further support for the theory or does it call intoquestion the validity of the theory as a whole?
Can you please help me? Thank you so much!
