Usually I’m firmly committed to the underlying principles of modern biology; natural selection seems like a perfectly fine way for happily adapted creatures to come into being.
About an hour ago, one of my offspring was with me in a public place with a well-traveled cement floor, onto which he accidentally dropped his gum. He picked it up and popped it right back in his mouth. Just now, this same small human organism refused to eat a piece of lettuce that had been in the same bowl with a cherry tomato. (I refuse to disclose whether I got him a bowl of pure and delightsome lettuce).
Shouldn’t this sort of behavior have been bred out of the gene pool a long time ago??
