Cannibalism. All species, from tadpoles to chimps, eat their own kind. Humans also do it under extreme duress or for darker reasons. Here are a few stories of what was considered the last taboo.
Wouldn't it be cool if even a few of the old stories were true? Legends say that giants walked the Earth, Atlantis vanished under the sea, and Greece and Troy fought a devastating war over a beautiful woman. Amazing, but true: all these stories are based on facts.
Archaeologists digging in China discovered the fossils of Gigantopithecus, a giant ape standing 9 or 10 feet tall. These huge but probably gentle apes died off 500,000 years ago. Traditionally, villagers collected their bones and made them into medicines. They called their finds dragon bones. Some have wondered whether pockets of the animals may have survived into later centuries, giving rise to the legend of Big Foot.
