quote:Originally posted by GordonPI wonder what caused a particular species of ape to evolve an upright posture in the first place and what was the driving evolutionary force that totally changed the hip bone of this particular species.
quote:Originally posted by neilepThis is an interesting topic.I would have thought that it was a necessity for us to stand upright was at least two fold.1. Being upright is an invaluable ability for protection from being hunted2. In contrast , being upright is a distinct advantage when it comes to hunting as the taller you are the further you can see unsuspecting dinner !!..additionally, being upright helps to serve to reach higher fruits from trees etc.Walking upright was probably one of the main landmarks that set us apart from the other apes. This must have contributed enormously to the manner in which our evolution was affected. Men are the same as women, just inside out !
quote:Originally posted by GordonPHi NeilepStanding upright offers no advantages over an ape sitting high in a tree.The question is. Why did one particular species of ape abandon the safety of the trees for a life on the ground? Remember although evolution, given the right circumstances, can happen comparitively quickly, this species of ape must have survived on the ground for thousands of years before the transformation of the pelivic bone was complete. How did this species survive for long enough for the process to reach completion?G W Pipes

quote:Originally posted by GordonPI don't think so George, the climatic change that affected North Africa when the sub-continent of India came into contact with Ero-Asia must have happened slowly enough for all the apes to follow the retreating trees into central Africa. We are still talking about a massively large area of jungle, big enough for all the apes.Why did our ancestors stay behind? And how did they survive long enough to evolve into the human species?G W Pipes
