News Finding: "Genetic inheritance continues to be critical for the capacity to quickly learn an adaptive behavior, but environmental factors that are stable over generations remove any selective pressure for the development of parallel genetic mechanisms."
Paper Finding: Indeed, it is a tenet of the best-known evolutionary psychology research approach that the dispositions to behavior presumed to have been differentially adaptive for women versus men in our ancestral past should persist in contemporary, modern humans (for an overview of numerous evolutionary approaches, see ), with environmental and social factors only modifying their manifestation in behavior.
News Context: "Even in non-human mammals, adaptive traits that have reliably developed in offspring for thousands of years can disappear within a few generations, if the relevant environmental conditions change," said Professor Dupre. "Genetic inheritance continues to be critical for the capacity to quickly learn an adaptive behavior, but environmental factors that are stable over generations remove any selective pressure for the development of parallel genetic mechanisms." Professor Joel said: "Masculine and feminine behaviors cannot be explained by the existence of male and female brains, as has previously been suggested.
Paper Context: Together, all these sociocultural factors result in both short-and long-term effects of sex categorization on the development of skills, attitudes, experiences, and, of course, the brain, mediated by gender socialization, including self-socialization . Indeed, it is a tenet of the best-known evolutionary psychology research approach that the dispositions to behavior presumed to have been differentially adaptive for women versus men in our ancestral past should persist in contemporary, modern humans (for an overview of numerous evolutionary approaches, see ), with environmental and social factors only modifying their manifestation in behavior. Stability of environmental factors over generations can guarantee the reliable reproduction of a trait across generations, and also can remove any selective pressure for the development of parallel stabilizing genetic factors.
