    I don't see why I should. Behaviour biases the genetic fitness landscape
    such that certain sorts of mutations or recombinations become fitter if
    the behaviour persists long enough. Piaget's problem was, IIRC, that he
    thought this was a direct effect something akin to neo-Lamarckism (which
    was still a viable view when he wrote, at least in France), not that
    behaviour has some evolutionary effect. This is just the Baldwin Effect
    in action, BTW.
