Neanderthals lived about 400,30 to 2021,100 years ago, spreading from southern Europe to Central Asia. Neanderthals knew how to cook plants and eat foods rich in carbohydrates, so they cooked grains and tubers.
Evidence shows that they used various methods, including heat as soon as they could light fires, and sometimes fermentation, and the third method was by (soaking) in water. Researchers think about the need to consider leftovers as artifacts, because cooking is an activity that requires craft and skill.
