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.
