Eons ago, when man lived in caves, dumb moves were often fatal moves. The quick and the smart survived, the slow and the dimwitted didn't. If one member of the tribe ate a berry and died, the others henceforth avoided those darn berries. Over time, humans advanced and grew sturdier. Not anymore. Now we've got seat belts, air bags, antibiotics and stomach pumps to save fools from their own mistakes. That's all right. Caring for others is one of the nobler traits of our species. The result, ironically, is that the genetic future of mankind isn't so rosy. Stragglers once culled from the herd now operate motor vehicles, watch Jerry Springer, cavort in pollution and even breed. Darwin would be truly worried. The evolutionary gap between the bacteria and us is closing. (en) |
