Ancient Poop Suggests Neanderthals Ate Way More Veggies Than We Thought

Meat-heavy "paleo diets" have been all the rage in recent years. But if you really want to eat like a caveman, you may have to eat more veggies than you might have expected.

A new study suggests that Neanderthals consumed way more vegetables than scientists once thought -- and the evidence for that finding came from a pretty unexpected place: ancient poop.

Or, more specifically, traces of Neanderthal feces taken from a Spanish cave.
