Caveman menu: Woolly rhino in Belgium, mushrooms in Spain

A new study says eating like a caveman depends on the location of the cave. In Belgium, a Neanderthal chowed down on sheep and woolly rhinos, yet in Spain they munched on mushrooms, pine nuts and moss in Spain.

Scientists got a sneak peek into the kitchen of three Neanderthals by scraping off the plaque stuck on their teeth and examining the DNA.

What they found smashes a common public misconception that the caveman diet was mostly meat. They also found hints that one sickly teen used primitive versions of penicillin and aspirin to help ease his pain.

Alan Cooper, director of the Australian Centre for Ancient DNA, said genetic tests showed which animals the 42,000-year-old Belgian Neanderthal ate: sheep and rhinos that roamed nearby.

The study is in Wednesday's journal Nature.
