...Everything that’s not asexual has two sexes, male and female. Most of the time it takes one of each to reproduce. Then there’s the whiptail lizard. This is a lizard that lives way the fuck out there in the middle of the desert, and sometimes it’s hard to find another lizard to mate with out there. Therefore, what the female whiptail can do is sort of make her eggs start dividing on their own. She makes daughters, clones of herself. It’s called parthenogenesis.
