This might be the worst death ritual ever. Endocannibalism is a practice where people eat their own dead.
The idea behind the horrid custom could be anything; from imbibing the deceased's traits to assimilation of the spirit.
A few tribes in South America and Australia are said to have practiced this creepy ritual. But many academics feel that endocannibalism is a false accusation thrown at tribes by early colonists to gain an excuse for political domination.
According to anthropologist Napolean Changon, the Yanomamo community in South America still eats the ash and ground bones of the deceased after cremation.
