Male birds also wear and display decorative plumage in order to attract mates, whereas female birds tend to be more drap. Obviously it's natural for men to look and dress prettily in order to demonstrate their attractiveness to women, who as the ones being wooed don't need to put in the same kind of effort.
It's funny how selective our analogies to nature are sometimes.
You completely missed the point. The point is that there are many examples of similar behaviors that aren't learned in lower animals that don't have the ability to learn much of anything the way humans do.
Thinking up an example of a different trait attributed to the opposite sex in humans is completely irrelevant.
If you want to address this subject in a meaningful way -- rather than find a nit-pick over an analogy while obtusely missing the point, maybe you should look into refuting the mountain of twin study evidence that shows that nurture lost in the nature vs nurture debate.
