This is a cop-out. There is nothing anyone does that couldn't be plausibly cast as an evolutionary imperative. You gave your kid the last bite of your dinner? Obviously you were trying to maximize his chance of surviving and reproducing. You kept the last bite for yourself? Obviously you were nourishing yourself to ensure your ability to provide for your kids in the future. You gave the last bite to the neighbor's kid? You must have been supporting your community because your kids thrive when your tribe thrives. You sent it off to starving children in Africa? Clearly you were trying to cultivate a reputation of charitable giving in order to increase your status in the tribe. This is a parlor game, not a reasonable way to talk about whether whales can display behavior we usually associate only with humans.
