Evolution confuses me. A woman wondered aloud last weekend if we really descended from chimpanzees, why are there still chimpanzees? And another person thought a better question is why aren't we still evolving into another genus? We could ask the Denisova Hominidae, but they left the planet 30,000 years ago. I saw Dr. Wilson speak at MSU a couple years ago. He's engaging and smart as any five people I know, and he writes, not quite down to my level, but enough that I can glean a little of the genius work he's accomplished. He loves ants. He likes all eusocial groups which include bees and wasps, and one particular gang of shrimp. He'd like to make a case for humans being a eusocial group, too, but when was the last time a despot ant queen made a decision to make you a drone or a breeding sister queen? When was the last time you sacrificed a long-held personal goal in favor of the group's success? Altruistic reciprocity is in our future perhaps. All I can think of is Spock in Star Trek changing his mind that the good of the many outweighs the good of the one. Humans have a few genes that select in the direction of group behavior; and a fistful that lean toward independence. That's why we're not likely to sort it out before we consume our nest completely. Wilson changed his mind in the face of newer research. He and Spock have my utmost respect.
