Reviewing key empirical findings in evolutionary psychology

Evolutionary psychology, like sociobiology before it, generally relies on a single level of functional analysis – phylogenetic, reproductive selection (natural selection). Behavior is thought to be a function of evolved mechanisms expressed in the modern environment, where culture accounts for a variation in that expression rather than having any substantial, independent causal role. No complementary, extensional functional analysis of behavior shaped as a function of reinforcing and aversive consequenses is usually taken into account. Neither for individual life-histories, or socially interwoven with each other as a culture. I review selected examples of influential research in light of this. But does it make a difference? I seek to answer what the evolutionary theorist relying only phylogenetic functional analysis is missing, if anything.
