Neanderthals were a different species to humans.The brain of a Neanderthal had a raised larynx, and was also bigger than that of the Homo sapiens.lthough, the difference between humans and Neanderthals when compared to apes is small. Neanderthals had a small population in the relatively recent past, and have no genetic or evolutionary connections with humans.
