The Famous Abeling Tail

A common bit of parenting folklore holds that babies tend to look more like their fathers than their mothers, a claim with a reasonable evolutionary explanation. Fathers, after all, do not share a mother's certainty that a baby is theirs, and are more likely to invest whatever resources they have in their own offspring. Human evolution, then, could have favored children that resemble their fathers, at least early on, as a way of confirming paternity.
Well Abelings know their babies are theirs because of their tails.
I'm not sure what happened with Brandon - we don't talk about that ;)
