In suggesting this period, I was deferring to what I understood was
the judgement of those more qualified. Namely that hominids retained
significant grasping ability in the foot until after 3 mya. If the
process started at 5mya, that's > 2Myr.
I'd be happier with a much shorter period, say 0.5Myr. But the
presence and use of trees would inhibit it.
How about an expert opinion from you, Alex, or anyone as to the
appropriate period?
