How does Darwin explain this?

@harveywilcox apparently this kind of abberation isn't that rare but a matching pair of bumps on the skull seems particularly unusual. And the female brown duck that was with him also had a matching pair of feather protuberances, so that's wierd.

Is it a case that you end up looking like your husband (or marrying someone you look like?)

@harveywilcox or peer pressure
