All you need to know about the world's remaining cannibal tribes

Living in tree houses high above the forest floor, the Korowai have traditionally practiced cannibalism as a way to honor the spirits of their deceased ancestors. They believe that by consuming the flesh of their loved ones, they are able to absorb their strength and wisdom. Another well-known cannibal tribe is the Fore people of Papua New Guinea. In the 1950s, it was discovered that the Fore were experiencing an epidemic of a mysterious neurological disease called Kuru, which was eventually linked to their practice of consuming the brains of their deceased relatives as part of funeral rites.
