there’s so much homophobia happening in this ask but like, lowkey i’m most offended by the characterization of me as a biochemist
I’m a biophysicist thank you very much
also, get fucked asshole
I love when ignorant jackasses try and say this shit because then I get to tout out one of my favorite natural phenomena: The Whiptail Lizard. Several entire species of lesbian lizards that have sexual interaction with each other to trigger self-fertilization.
So, no. There are actually multiple species that are entirely gay that are doing just fine! Teiidae is just one example. Any species capable of parthenogenesis, which includes insects, invertebrates, fish, amphibians, reptiles, and some birds, could sustain an entirely gay population, and some already do.
There are also plenty of species that engage in same-sex mating more often than male-female mating that are doing absolutely fine. Like giraffes, most cetaceans, most primates, and most damsel and dragonflies.
There was a pair of gay penguins in a zoo that successfully adopted an egg from a couple that abandoned it and raised it together…
That’s actually pretty common along quite a few species of birds.
There are multiple bird species where abandoned or orphaned chicks are regularly adopted by same-sex pairs who are unable to have their own babies. A reasonable argument could be made that having a portion of the population be interested in same-sex partners is beneficial, as those pairs, unable to have their own offspring, will adopt any orphaned or abandoned offspring and raise them to adulthood.
