Men with superior navigational skills father more children

SHAFAQNA –  It’s no secret that many men take pride in their superior spatial and navigational skills; so much so, in fact, that they have become the brunt of many a joke about failing to stop and ask for directions. Women have long thought it was tied to their ego, but until now, no one really knew why. According to a Nov. 14 report by the American Association of the Advancement of Science (AAAS), recent research suggests that advanced navigational skills may be a reproduction benefit in males.

University of Utah study of the Twe and Tjimba tribes in northwest Namibia revealed that men with better spatial skills traveled a wider distance and had children with more women. The study’s senior author, Elizabeth Cashdan explains that relative to other cognitive differences, the difference in spatial skills between men and women is large and is observed across cultures. This suggests that the development of spatial and navigational skills is evolutionary in nature and may speak to the survival of the species.

In sexually open cultures, like that of the Twe and Tjimba tribes, where sexual encounters with others outside of a marriage in accepted, this translates to more offspring with several partners. In cultures, where traditional marriage is still the norm, the sexual benefits may be less important. But, that doesn’t mean that men won’t continue to act like it is.

It’s no wonder men are reluctant to stop and ask for directions, even when they are lost on the highway. Doing so may expose their lack of superior navigational skills and pose a threat their manhood. But then, that’s what the GPS is for – to quietly whisper the sweet nothings he desperately needs to hear. After all, the survival of the human race may be at stake.
