As Randy Moore and Sehoya Cotner explain in their new book Arguing for Evolution: An Encyclopedia for Understanding Science, this and most everything else in biology proves evolution to be an undeniable fact. Altruism, they explain, may seem to be a “problem” for evolution. (They put “problem” in quotes because, of course, there are no realproblems for evolution.
