Deep Dive Ep. 18 | Do Attractive Couples Have More Daughters?

In this episode, we talk about the evolutionary reasons why the most attractive couples have a 26% higher chance of giving birth to a daughter than the average couple. We discuss whether their attractiveness might be playing a role, or whether it might be caused by other mediating factors such as brain type, body size and language ability. Whether attractiveness does explain the phenomena has strong implications for what we know about the relative importance of physical attractiveness for men and women.
