## Resource

How do men and women differ? Where do the differences come from? And how do they shape modern life? Drawing on a century of research and a billion years of evolution, Steve Stewart-Williams explains why many sex differences appear despite socialization, not because of it; why in our mating and parenting patterns, humans are more like the average bird than the average mammal; and why sex differences are sometimes a sign of societal health rather than injustice. Steve Stewart-Williams is a professor of psychology at the University of Nottingham Malaysia. His first book, Darwin, God, and the Meaning of Life , was published in 2010. His second, The Ape That Understood the Universe , was published in 2018. His new book is A Billion Years of Sex Differences .
