 Bipedalism 

We know from the fossil evidence that bipedalism evolved before  larger brains and other characteristics seen in modern humans.  Scientists have come up with various hypotheses to explain why our  ancestors initially became bipedal. Using the material in the textbook,  summarize the hypothesis that you think best explains why bipedalism  first evolved, and then explain why you think this hypothesis is the  most convincing. Make sure to state precisely what scientific evidence  you use to support your choice. Your initial post should be at least 250  words in length.
