Did bipedalism in hominins evolve more than once?
It is quite possible that bipedalism evolved more than once in hominin history, according to a new article published in Nature.
The article is “A new hominin foot from Ethiopia shows multiple Pliocene bipedal adaptations” by Yohannes Haile-Selassie, et. al., published 28 March 2012. doi:10.1038/nature10922
This is another example of why anthropology is such a fascinating field. Enjoy.
