In college, my biology professor said, “if you don’t reproduce you’re considered a biological loser.” You can imagine my confusion about evolution and homosexuality—what a quandary.
My professor’s point was clear. To keep your genes going, you had to reproduce. Certainly, those of us who never had kids are not losers.
My professor’s statement got me thinking. What, if any, purpose does homosexuality serve?
Evolution and Homosexuality: The Birds and the Bees
We know homosexuality exists outside of humanity. In Bruce Bagemi’s book Biological Exuberance, we learned about the prevalence of same-sex species in the animal kingdom.
Male penguins mate for life.
Bonobo chimpanzees are a horny bunch. They don’t care what the sex is.
Same-sex dolphins adopt abandoned calves.
Could homosexuality serve a biological purpose for a species? The world is overpopulated. Could biology spawn individuals less apt to breed in order to take care of those left behind?
The “nest helper” theory is an interesting one. It’s been around for some time. The LGBT help the family. It makes sense from an unscientific view.
Are we the caretakers of society?God only knows. (Pun intended.)
God only knows. (Pun intended.)
Why is Homosexual Behavior Preserved in the Animal Kingdom?
If a certain trait is detrimental to the reproductive success or fitness of an organism, it’s not expected to persist in the population.
Darwin told us natural selection gets rid of that shit.
Bible thumpers will turn to scripture. “The LGBT are damned to hell!”
Yeah, right. What about Mr. and Mr. Flipper? Maybe they shouldn’t have rescued that poor pup whose parents were killed by a boat.
Biologists have been flummoxed by the gay thing for a long time. Gay creatures are clearly not going away. It can’t be detrimental.
Homosexuality has to serve a purpose.
In 2015, The Royal Society of Biological Sciences found that certain fruit flies (it’s always them fruit flies!) passed down same-sex behavior in their hatchlings. Females with the gay genetic makeup had higher reproductive rates. Yes, they produced more.
Does homosexuality make a species stronger?
Thirty-nine percent of same-sex couples in the United States have children in their household, according to a February 2013 report by The Williams Institute. Not all of them are their own genetic makeup.
There’s no one in my house under eighteen. I guess I am a biological dud.
Wait! Does adopting a dog count?
