Scientists studied the sexual selection of beetles for a decade to try to figure out why men exist.

Wait! We're so much more than just genetic material! (via Thinkstock)

Why do men exist? To provide genetic material, of course! But if that's all they're doing, why do they make up 50% of the population? Wouldn't we only need a couple of men around to fertilize eggs, before sending them back into their man caves? Don't worry, I'm talking about the animal world, because I know humans need men to help care for their offspring, install lighting fixtures, and make tough financial decisions.

Scientists at the University of East Anglia hoped to answer the question of the male gender by hypothesizing that men exist for sexual selection. They proved this by mating 50 generations of beetles for over 10 years to see if sexual selection played a role in the genetic outcome of the species. The study found that when females had a choice in male partners, the beetles survived longer and with fewer genetic mutations. You can read more details here.


So there you have it. Men exist not only to provide genetic material, but so females can choose which genetic material makes the best babies. I choose one of the middle-aged New Kids, thank you.
