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?
- jackcosgrove 9y agoI 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.
- throwgoog452 9y agoThe entire human body is a reproductive system. That's what life is. Evolution optimizes for behaviors as much as it optimizes for gonads.
