In looking at the first hominids (humans), What are the major issues? 1. What did the last common ancestor between human and chimpanzee lineages look like? 2. When did the split occur? 3. What factors favored the development of bipedalism? What natural selective forces? 4. HOW? Was bipedalism the result of a macromutation? 5. Were there separate lineages of early hominids, of which only one survived to lead to us, or were they all part of the same lineage?
