Another thread has me wondering, why don't male mammals nurse their young? Obviously they don't now, but I think it's "never" in the long history of mammal-like animals. Seems precarious, having only 50% of the parents available to keep the young alive. If the female parent dies the male has to watch his offspring die if they can't handle solid food yet.
