Differences between men and women
Scientists are finding differences between men and women!
In addition to the well-known anatomical differences, gender differences have been identified in brain connections and gait. We can identify a figure’s gender — and feelings — by the way it’s silhouette moves and carries itself. When it comes to interpersonal dynamics, we read and process subtle cues about one another, often at the subconscious level.
Take the results of a recent evolutionary study that found the facial features of men and their partners’ fathers to look more similar to each other than to random men. Why date someone who looks like dad? To take an evolutionary approach, there was a time when multiple hominid species coexisted. Finding a mate whose face is similar to that of a known relative could be insurance against mating with the wrong species. So what does that say about those of us who date the non-dad? How does interracial parentage fit into the evolutionary scheme of things — As a genetic population control mechanism a la kamikaze? Or to ensure hybrid vigor and outbreeding in response to environmental change?
With the rise of genetic and genomic testing, it was only a matter of time before matchmakers piled onto the spit-testing bandwagon. Inspired by the T-shirt sniffing test — in which MHC (major histocompatibility complex) was shown to influence body odor and mate preference — scientists formed Genepartner to provide identify romantic compatibility based on genetic testing.
Genetic matchmaking isn’t restricted to humans. Zoos have begun including genetic information about captive animals in their studbooks, with the hope of identifying successful breeding pairs for long-term species survival. Apparently koalas are extremely particular about mate choice. Who knew?
