Careful. The longer you stare down the looking glass at life, the more of a kaleidoscopic fractal it all becomes. Even “species” are loose, funny things.
In biology, a ring species is a connected series of neighbouring populations, each of which interbreeds with closely sited related populations, but for which there exist at least two end populations in the series which are too distantly related to interbreed, though there is a potential gene flow between linked neighbouring populations.
What’s interesting about sex being binary is that biology is really messy and hard, and it’s kind of amazing that we found such a universal definition.

Exactly. Ring Species are a good example
