Evolutionary scientists know we're not descended from Neanderthal. We have sequenced their complete DNA. It indicates we had a common ancestor about 700,000 years ago. They were the red haired "Europeans" and "Mediterraneans" and we were the Africans until 60,000 to 100,000 years ago when we began migrating out of Africa. Some time later in the Easter Mediterranean we were still able to cross breed with Neanderthal resulting in up to 4-5% of non African modern man DNA being Neanderthal DNA. Descendants spread throughout the world till today.
