I'd think about the question in the context of the theory of
evolution, but any answers that I formulated on that basis would be
very tentative.  Evolutionary theory doesn't provide for unambiguous
predictions, or even retrodictions (why do lions have manes?), since
it has no causal mechanism.  Again, it's more of a metaphorical
framework for thinking about possibilities.
