The correct answer is: "Chimpanzees and modern humans shared a common ancestor."
The chimpanzees are not the ancestors of modern humans as because humans did not come from chimpanzees but from a common Hominin ancestor. Neanderthals on the other hand, are also not ancestors of the humans but also shared a common ancestor albeit an earlier one compared to the chimpanzee. Most ancestors of humans originated in Africa, not in Europe.
