Cannibalism is the act of consuming the flesh of one's own species. In humans, it has occurred throughout history for various reasons, including survival, ritual practices, and cultural beliefs. Some societies have viewed it as a taboo, while others have incorporated it into their traditions. In the animal kingdom, cannibalism is more common and can serve different purposes, such as population control or resource competition. Certain species, like praying mantises and crocodiles, may eat their own kind, especially in times of scarcity. This behavior can be a natural part of their survival strategy.
