> I don't think evolution would necessarily favor specialization between the sexes.
Why wouldn't it? Other primate species are very sexually dimorphic, both physically and behaviorally. Why should humans be so fine-tuned that there are no sex differences at all in behavior?
I meant across all species. I do acknowledge sexual dimorphism among humans, and provide a mechanism for this happening based upon the effective population sizes of mating humans.
I just think the top level post's claim should be reeled in a little bit to not imply that all species that manifest sex should result in sexual specialization beyond the reproductive system.
