Summary: Important events occur before birth or hatching, both in terms of embryonic movements and the influences of incoming sensory information. The extent of significant contributions to postnatal development can depend on how "altriciality" or "precociality" of the species. Related to this are the kinds of sensory systems that develop both prenatally and postnatally, including an interesting evolutionary constancy.
