Biology Prevents Men to Pursue Friends' Wives, Claims Study

Scientist have discovered that a man's biology may prevent him from attempting to pursue a friend's spouse or girlfriend, a new study shows.

In a study of associated testosterone levels in men, Mark Flinn, a professor of anthropology for the University of Missouri, found that men's bodies respond differently to friend's significant others than potential sexual partners.

"Although men have many chances to pursue a friend's mate, propositions for adultery are relatively rare on a per opportunity basis...Men's testosterone levels generally increase when they are interacting with a potential sexual partner or an enemy's mate. However, our findings suggest that men's minds have evolved to foster a situation where the stable pair bonds of friends are respected."

Flinn explains that evolution has put in this biological filter for partner selection comes down to social cooperation. Men who do not encourage familiar stability and break friend's trust endanger the whole community and does not give it a better shot of survival. This enabled our early ancestors to form groups and work together to survive. Today, this can explain how modern-day humans can come together and act as one global community, according to Flinn.

"Ultimately, our findings about testosterone levels illuminate how people have evolved to form alliances...Using that biological understanding of human nature, we can look for ways to solve global problems. The same physiological mechanisms that allow villages of families to coexist and cooperate can also allow groups like NATO and the U.N. to coordinate efforts to solve common problems. The more we view the Earth as a single community of people, the greater our ability to solve mutual threats, such as climate change."
