Re: Some Female Lizards in the Wild

I thought it was pretty well accepted that genders arose to help mix it up in the genes department, because a lot of variation helps protect the species in the face of endless threats. If you've covered all bases, then no matter what disaster Mother Nature throws at you, the species will have a few individuals that survive. This seems more efficient than relying on the also-occuring random mutations. But if you need to reproduce and you are too thinly spread to find a mate, you go for parthenogenesis and hope random mutations protect the species. Or, if you are in a stable enivronment that isn't throwing threats at you, why complicate things? Stick to parthenogenesis.
