How Darwin Can Save Your Marriage (VIDEO)

In this Big Think video, psychologist Christopher Ryan discusses how we live in a world that upholds sexual monogamy and fidelity as relationship ideals; however, this sharply conflicts with what he believes is a natural human tendency toward non-monogamy. Ryan talks about how human beings are programmed to be "titillated" by that which is new and how our need for sexual novelty goes unmet in completely monogamous relationships.

Ryan argues that modern day marriage needs to adapt to the reality that monogamous relationships may not come naturally to us and that we need to stop taking an "absolutist" approach to lifelong fidelity. In his words "sex isn't really that important," so if you or your partner occasionally strays, what's the big deal?
