曾看到一篇题为《幸福蜥蜴》的文章:杰恩斯教授养了一只稀有的亚马逊蜥蜴当宠物。头几个星期,蜥蜴不肯吃东西,一天天消瘦下去,眼看就要饿死。有一天,杰恩斯把看完的报纸放在火腿三明治上。蜥蜴看到后,立刻在地板上匍匐前进,跳上报纸,把火腿三明治扯碎,把它吞下。原来,蜥蜴已经进化成需要、攻击、撕裂,然后才进食。 Had seen an article entitled “Happy Lizard”: Professor Jaynes has raised a rare Amazon lizard as a pet. The first few weeks, lizards refused to eat, day by day weight loss, seeing starve to death. One day, Jaynes put the newspapers he had read on a ham sandwich. Immediately after the lizard saw it, he crawled on the floor, jumped onto the newspaper, shredded the ham sandwich and swallowed it. It turned out that lizards have evolved to need, attack, tear, and then eat.
