Humans have been eating other humans since the beginning of time, but the motivations behind this macabre practice are complex and often unclear. Some anthropologists say prehistoric cannibals were just trying to grab a nutritious snack, but new research shows that human flesh -- as tasty as it is -- doesn't pack the same caloric punch as wild animals. In other words, cannibalism wasn't worth the trouble given alternatives.

Predicting the future is near impossible -- but that doesn‘t stop us all from having a red hot go. Human beings have been predicting the future since the beginning of history and the results range from the hilarious to the downright uncanny.
