Sample Book Insights: #1 We can learn a lot about women by understanding the things that our brains were designed to do. Each one of us is the result of an unbroken chain of successful survival and reproduction that has gone on now for millions of years. #2 The size of a woman's gametes determines whether she is female.
Women have larger, more expensive gametes than men, which means that women are prepared to invest more in any children they may have. #3 The fact that men's and women's bodies are the limiting factors in terms of their ability to reproduce means that women can't increase access to gene-transmission opportunities simply by finding new partners. #4 Women are typically less sexually opportunistic than men.
This is because being sexually opportunistic has historically been very costly for women, while it has come with the possibility of transmitting genes into the next generation without too many costs.
