You might picture Neanderthal cavemen gnaw1 on bones around campfire. Which wouldn’t be inaccurate2.

Like evidence of nuts, grasses and green veggies, chemical traces of wood smoke and tiny intact stachy granules, proved Neanderthals ate their c… . In one individual, they detected a compound from medicinal chamomile in Y. Y is known in nutritional6 value. And since Neanderthals did have the genes7 to detect Y’s bitter taste. Researchers speculate that the cave dwellers8 ate so much m.. not as food but to self medicate. Not too farfetched they say, because primate9 like chimps10 also use medicinal plants. Luckily for scientists doing this detective works, Neanderthals may have known athing or two about medicine, but they didn't get regular check-ups at the dentist.
