25. The extent to which ovulation truly is hidden in humans is not as settled a matter as many authorities claim. There is good reason to believe that olfactory systems are still able to detect ovulation in women and that such systems are significantly atrophied when compared with those of ancestral humans. See, for example, Singh and Bronstad (2001). Furthermore, there is reason to believe that women advertise their fertility status via visual cues such as jewelry and changes in facial attractiveness. See, for example, Roberts et al. (2004).

In 1785, Benjamin Franklin visited the hospital where Rousseau had deposited his five illegitimate children and discovered a mortality rate of 85 percent among the babies there (“Baby Food,” by Jill Lepore, in The New Yorker, January 19, 2009).

3. Trivers’s paper is seen as the foundational text in establishing the importance of male provisioning (investment) as a crucial factor in female sexual selection, among other things. It’s well worth a read if you want a deeper understanding of the overall development of evolutionary psychology.

9. This sacred regard for each individual’s autonomy is characteristic of foragers, too. For example, when Michael

Finkel visited the Hadza recently in Tanzania, he reported, “the Hadza recognize no official leaders. Camps are traditionally named after a senior male ... but this honor does not confer any particular power. Individual autonomy is the hallmark of the Hadza. No Hadza adult has authority over any other.” (National Geographic, December 2009.)

14. (Photo: Christopher Ryan.) When I saw this old woman, I knew her face contained the feminine strength and humor I was hoping to convey in a photo. I gestured to ask if it would be all right to take her picture. She agreed, but asked me to wait, and immediately started calling. These two little girls (granddaughters? Great-granddaughters?) came running. Once she had them in her arms, she gave me the go-ahead to take the shot.

15. The book was published in 2002, while Goldberg’s came out almost a decade earlier, but all of Sanday’s work on the Minangkabau, including the paper Goldberg cites, argues against his position—a point certainly deserving of mention.

21. Things have become a bit more muddled since Insel said that. More recently, Insel and others have been working on trying to discover the hormonal correlations underlying the fidelity or lack thereof among prairie, montane, and meadow voles. As reported in the October 7, 1993 issue of Nature, Insel and his team found that vasopressin, a hormone released during mating, seemed to trigger protective, nestguarding behavior in some species of male voles, but not others, leading to speculation about “monogamy genes.” See http://findarticlescom/p/articles/mi_m1200/is_n22_v144/ ai_14642472 for a review. In 2008, Hasse Walum of the Karolinska Institute in Sweden found that a variation in the gene called RS3 334 seemed to be associated with how easily men bonded emotionally with their partners. Most interestingly, the gene appears to have some association with autism as well. The reference for Walum’s paper is Proceedings of the National Academy of Sciences, DOI: 10.1073pnas.0803081105. A news article summarizing the findings is online at http://www.newscientist.com/article/dn14641-monogamy-gene-found-in-people.html.
