It is a significant discovery because it demonstrates there was more than one pre-human species living in East Africa between three and four million years ago, each with its own method of moving around.

I am much more interested in this, since going to a lecture about the human evolution ...I can understand there being more than one group in Africa who started walking upright but maybe they didn't evolve further and died out because they didn't adapt further or desease, inbreeding, etc,.. stifled their evolution...

I think this is still a mystery. I wonder if there was any attempt for both groups to interbreed. It was kind of odd, though, about the short big toe.

And yeah, it does look like this "new human" would be more likely to be tree climbers. That said, maybe they they were more likely to stay in one place, whereas the Lucy group might be more likely to move on.

could the big toe be due to a mutation?
Maybe a male took some females with him after a fight between him and another male? Wouldn't you think they fought over females and territory like any animal?

It could be that the two branched somehow, back before Lucy was around.

Maggie, do apes only have four toes or is it that they have all the same size toes to where as we have a 'large' toe?

I'm not sure how the "new" one walked. I'll ask when I get a chance.
