«THERE SHOULD BE COURSE IN FIRST GRADE ON LOVE»

In a man, the craggy physical characteristics associated with masculinity often indicate a strong immune system and thus a likelihood of his producing healthier offspring than his softer-featured confrères will. But such men are also more promiscuous and do not care as much about long-term relationships, leaving women to raise their kids alone.Nowadays, sound parenting is often more important to the viability of a man’s offspring than Herculean strength. That, some researchers suspect, may be changing the physical traits that women look for in a mate, at least in some societies. A study carried out in 2004, for example, discovered that women in rural Jamaica found manly types more desirable than did women in Britain, which led to questions about whether those preferences were arbitrary or whether women in different parts of the world might be adapting to circumstances that place different emphasis on manliness in the competitive calculus.Dr Jones and Dr DeBruine therefore looked to see if there is an inverse relationship between women’s preference for masculine features and national health. Sure enough, they found one. In environments where disease is rampant and the child-mortality rate is high, women prefer masculine men. In places like America and Britain, where knowing how to analyse health-care plans is more important than fighting off infection, effeminate men are just as competitive
