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?
