Biologically based behaviors are viewed as highly situation dependent, constrained, and shaped by local history and environments. This perspective is illustrated by tracing through time changes in the patterning of parental behavior toward sons vs. daughters. Although it is assumed that decisions about parental investment are rooted in evolved predispositions, parental behaviors change in response to changing conditions affecting the productive and reproductive contributions of sons vs. daughters.
