And lastly this rather brilliant input in comment #45 from an anthropological paper by Evelyn J Bowers: New Perspectives and Problems in Anthropology pointing to the possibility of the fusion of chromosome #2 may have been associated with the development of bipedalism . (You can also attribute all this to Aliens or that God just introduced a fused chromosome #2 with Noah & his wife on the Ark , therebye creating a new race of hominids , your choice and go on quoting Creationist websites ) What is of interest here is the Hox gene found in Chromosome 2 Chromosome #2 may have been associated with the development of bipedalism (walking upright), because the fusion of chromosomes could have altered the function of the Hox B genes which are now found on our chromosome two. The Hox B genes are one of several groups of genes which control morphology, and the Hox B genes (on chromosome 2) specifically control the way the pelvis and lower spine and genitalia develop. Humans have five lumbar vertebrae, chimps have three, so it's very plausible that that's one of the changes that led to walking upright.
