The story on the front page of SAGG Torturous terrain behind human bipedal evolution? tells about a study that suggests that hominins became bipedal in response to a need to live in a mountainous, or at least rugged area. The authors of the study suggest that climate change caused some of our ancestors to wind up having to live in rugged terrain, and it would be easier to navigate bipedally.

My opinion is that I will wait for more information. While it seems to have some logic to it there seems to me to be a lot of evidence that we first started to become bipedal while we lived in a wooded area, not a mountainous area.
