【英语时差8,16】为什么同类相残不常见（上）

Have you ever wondered why cannibalism¹ isn’t more popular? Just think about it: each animal is made of a complex variety of chemical ingredients. As an animal, we can either try to assemble these ingredients haphazardly², eating other animals and plants and hoping these assorted³ meals will add up to exactly what we need. Or we can get all our essential nutrients⁴ in one complete package by dining on our next-door neighbor! You might think that cannibalism would be a good long-term survival strategy. Indeed one study has shown that tadpoles⁵ that dine on tadpoles grow bigger than those who don’t. Why isn’t cannibalism more popular in the animal kingdom?
