Re: Some Female Lizards in the Wild @ John H Woods
Must have been *quite* a while then.. between recombination and paternal and maternal masking at meiosis alone , you get the advantage of having a backup in case mutation ends you up with something undesireable, and a *much* higher expression of , potentially beneficial, mutations in the phenotype. It's all about rigging the numbers to be able to fill the existing habitat as quickly and as efficiently as possible.
I do like the flame-bait in the article though. But if even single-celled eukaryotes see reason to produce gametes on occasion, and even bacteria see fit to merge and do some DNA hussling if circumstances allow, I think I can safely say that "males" are pretty much indispensible in the whole process.
