Like the ‘it’s only natural’ argument is such bull tbh. Like studying natural behaviour and stuff, Gender roles in nature are so varied and arbitrary. It’s so stupid to assume males are usually dominant. Like, here are just some of the many, many, many examples:
Matriarchal Species: Killer Whales, Spotted hyenas, BEES, Meerkats, Ants, Mole rats, Buffalo, Clownfish, Lemurs and (our closest relatives) Chimps!
Species where males stay home look after the kids: Sea Horses, Marmosets, Giant water bugs, Sandpipers, Reas & Emus, Bat-ear foxes, Some frogs
Species Where females are usually more promiscuous: Topi Antelope, Chimps (again ;) ), Hedge Sparrows, Antechinus (marsupial shrews)
Species that are often gay/bisexual: Dolphins, Penguins, Ravens, Elephants, Reindeer, Bears/Pandas, Albatross, And (surprise surprise) Chimps (in fact 60% of female bonobo chimps exhibit homosexual activity).
Species that can physically change gender/change gender behaviours: Clownfish, Cuttlefish, Common Reed Frogs, Gobies, Bearded Dragons
This is literally the tip of the iceberg. I could even say gender roles like ours are not the majority in nature. Hell, There’s are even new studies that suggest that the gender roles of early man where the reverse of what they are today. So basically there’s nothing natural about traditional sexuality or gender roles. They are very much man-made, socially constructed.
