Sex at Dawn

In order to move the needle forward on our conversations about monogamy and infidelity, we must be willing to discuss our true desires, even if they feel socially taboo. The more open we can be in sharing our personal stories, the more likely we are to bridge the gap between our culture’s promotion of monogamy and our biological belief in sex with multiple partners. Do not immediately write off the possibility of sexual inclusivity within a nuclear family household.

Additionally, rather than shying away from discussing sexuality with our children, we must engage adolescents in these complex, multi-faceted topics. 

Christopher Ryan, co-author of Sex at Dawn: The Prehistoric Origins of Modern Sexuality, is married to the book’s other author, Calcilda Jetha.

Prior to publishing his debut text, Ryan attended Saybrook University in San Francisco, California where he completed a Ph.D in psychology. Ryan’s doctoral thesis focused on the prehistoric roots of human sexuality, which ultimately became the basis of his writing.

Currently, Ryan hosts a popular podcast called Tangentially Speaking, which aims to inspire individuals to take stewardship of the planet.
