The answer the people demand, to the question that somebody asks every 6-8 months
Europeans didn't learn about electric eels until after they learned about electricity. There are electric catfish in the Nile, and they were called thunder fish.
Native S. American peoples called electric eels something that translates to: the fish that takes away movement.

Hey, fellow evolutionary biologists:
If you support trans rights, like, comment, or repost this. I want to show that transphobes like Richard Dawkins are a loud minority that does not represent our community

And that’s a follow.
Actually I do have a question if you have a sec.
Without exception the most transphobic group of scientists I’ve run into online are evolutionary biologists. Every single one of them has expressed the same opinion: transness cannot be anything other than social contagion. Why?
