The Man They Called Universe

Have a chart regarding the sex system of Koyol’s people who are since extinct. they did not have a binary sex system, nor did they have sex-based pronouns. Instead, they had a 4-sex system of mating, and a very complicated network of pronouns based on rank, age, and other things. 

They didn’t even have actual names for three of their four sexes. “Maker” “taker” and “giver” are just phrases to reference what one’s body was capable of. other phrases could include a “taker” referring to their ability as an “egg layer.” it’s just a description of what one can do. the only exception was “perfect” which had a pronoun title all it’s own.

Koyol is, of course, none of these sexes, he’s a mutant unrelated to their species. But since he’s generally a fully-capable and adaptable mutant at breeding, he could be considered a functional hermaphrodite / perfect hermaphrodite (and his human counterparts, considered Intersex.)

Theres is a much more In-Depth Explanation of their extinct Biological Sex System HERE which also includes some interesting explanations and details regarding Koyol’s own complicated, mutated sex systems, and just a little bit about his opinion on gender (although not much, because this was more about his and his peoples biological sex differences, and less about gender and identity, and how truely far removed from a binary system he was raised with).

So I just discovered that there's a kind of salamander that takes entire genomes from males of different species and mixes them up however it pleases. I can't even say it's a "species" because a single individual can have the entire genomes from four different species knocking around in it, so scientists just refer to the "unisexual" members of the genus (because they're all female).

We don't even know what salamander they're originally descended from, because at some point they threw that genome out. Only the mitochondrial DNA are the same in this fucking ship of Theseus of an amphibian. Please keep in mind that it's commonly accepted that the whole purpose of an organism is to propagate its DNA. This salamander said NOPE.
