看到了吧,在很久很久很久以前,狼也会吃同类的粪便,不管对方是不是老弱病残,不管这坨便便的出现是不是为了清理狼窝。寄生虫和病原体要两天之后才会出现在粪便中,所以新鲜的粪便对食用者来说没什么危险。而且新鲜粪便会在狼的体内溃烂,能够有效避免幼虫和蠕虫寄生在肠道内。
That said, some great minds in the canine scientific community think there may be a bit more to it. For instance, Professor James Serpell of the University of Pennsylvania and editor of the recent book The Domestic Dog: Its Evolution, Behavior and Interactions with People, told theWashington Post he finds the wolf theory “plausible,” but he's also intrigued by the “greedy eaters” survey findings.
犬类研究圈认为好处不止于此。宾夕法尼亚大学教授詹姆斯·斯贝尔(James Serpell),刚刚完成了新书《家犬:进化、行为和与人互动)》,他告诉《华盛顿邮报》,狼理论“有道理”,但是“贪吃”调查的结果也让他很感兴趣。
He referenced a study of free-roaming wild dogs in developing countries that scavenge for food and, as a result, fill up on a sizable amount of human feces. This seems to indicate that poop could be viewed, errr digested, as a second-hand food source.
他举例说,发展中国家的流浪狗在寻找食物时,也会吃掉相当多人类的便便。看起来好像便便是狗寻找食物的第二选择。
