Definitions for "Innateness"
"Hardwired by genes" is the general idea, but it is, more generally, a bit of behavior that arises without learning. When the individual finds itself in a particular setting, out pops some complicated behavior. Mating behaviors are innate; some things are too important to be left to learning. But there isn't a dichotomy between innateness and environmental causation; as epigenetic rules show, something innate may have, via environmental triggers, profound effects on future form and function.
