One of Stanford University professor Eleanor Maccoby's key discoveries about childhood gender development is that girls and boys act far more alike on their own than they do with groups of their friends. Maccoby also offers sound evolutionary reasons why we might be biologically inclined toward sex- differentiated behavior. In the end, though, she asserts that "biology is not destiny."
With this in mind, she explores in The Two Sexes what sorts of changes can and should be made to the roles we play in our sexual relationships, work relationships, and parenting. This a complex and scholarly work, but Maccoby writes in clean, reasoned prose accessible to nonacademics. --Maria Dolan
