Re: Obligate Bimanualism

Those are good points, Marc.
Can you think of any short-tail or tail-less vertebrate terrestrial
that locomotes compressionally obligate bipedally which has similar
length arms and legs? I'd think there is none and has never been one.
Its a pattern/rule-of-thumb/law, AFAICT. If true, Lucy had to follow
the law. She was a locomotive generalist. Both her ancesters and her
descendants may have been obligate bipedalists, but she wasn't.
