Steve Stewart-Williams argues evolution shaped distinct male and female psychological drives
Psychologist Steve Stewart-Williams discusses his new book A Billion Years of Sex Differences regarding how natural selection influenced human minds.
Standard psychological sex differences
The author identifies reliably observed differences in sexuality, partner preferences, antisocial behavior, and parenting. He also notes robust distinctions in job choices and childhood toy preferences between the sexes.
Nature versus nurture debate
Stewart-Williams believes nature acts as the dominant player in creating these differences. He states that natural selection designed specific drives to help individuals survive and reproduce effectively.
Evolutionary design of the mind
The book suggests the best reproductive strategies sometimes differed for men and women throughout history. Consequently, certain mental devices were designed differently in male versus female minds to address these varying needs.
