Many lower life forms demonstrate qualities that, at first, just don't seem survival oriented. For instance, the female praying mantis, after mating with, well, her mate, will devour him. For the male praying mantis, however, it's a catch-22. If he mates, he gets screwed out of an opportunity to mate again. If he doesn't mate, he doesn't reproduce, ending his family tree. This suicidal behavior is commonly called the Preying Mantis Syndrome -- and many life forms are periodically subject to its wrath. How did the preying mantis become stuck in such a awful, vicious cycle?
