...Martie Haselton, a psychologist at UCLA, is exploring the forces that may have shaped those more primal attributes into modern love. She believes it all comes down to the long-term health of children. Haselton calls romantic love a "commitment device," a mechanism that encourages two humans to form a lasting bond. Those bonds help ensure that children survive to reproductive age, getting fed and cared for by two parents rather than one. "Natural selection has built love to make us feel romantic," she says...
...experiments, Haselton finds evidence for love as an adaptation. She and her colleagues have people think about how much they love someone and then try to suppress thoughts of other attractive people. They then have the same people think about how much they sexually desire those same partners and then try again to suppress thoughts about others. It turns out that love does a much better job of pushing out those rivals than sex does. Haselton argues that this effect is exactly what you'd expect if sex was a drive to reproduce and love was a drive to form...
...Human Behavior showed that strippers who are ovulating average $70 in tips per hour; those who are menstruating make $35; those who are not ovulating or menstruating make $50. Other studies suggest that men can react in more romantic ways to olfactory signals. In work conducted by Martie Haselton, an associate professor of psychology at UCLA, women report that when they're ovulating, their partners are more loving and attentive and, significantly, more jealous of other men. "The men are picking up on something in their partner's behavior that tells them to do more mate-guarding," Haselton says...
...anonymous males and then pick which ones appealed to them. Time and again, they chose the ones worn by men with a safely different MHC. And if the smell of MHC isn't a deal maker or breaker, the taste is. Saliva also contains the compound, a fact that Haselton believes may partly explain the custom of kissing, particularly those protracted sessions that stop short of intercourse. "Kissing," she says simply, "might be a taste test...
