I do appreciate the research because it gets at what a lot of people have been thinking about for a long time, <em>Orrorin</em> is more closely related to australopithecines than humans. Just seems like they went about it a strange way. Looking for bipedalism by measuring and comparing the outside of the bone seems not as authoritative as measuring within the bone.

I know its not very common to do the following for post-cranial elements, especially for this where it's based on just 8 measurements, but I would have much preferred to see a distance-based analysis (Pongo as outgroup) with least squares and neighbor-joining rather than the UPGMA. Still a nice little paper IMO. I found the UPGMA clustering a little kooky.

Send me what you got, but I think I may have any reference of him on <em>Orrorin</em>. Who knows, I could be wrong! Thanks, Kambiz Yeah, White was the co-author in the Ohman et al. paper.

If you need a copy of the White article I can send it. White tore into the CT study and its methodology big time too. If you need a copy of the White article I can send it.
