Some other ideas of what Neanderthals looked like:
What if we brought Neanderthals back and they really were smarter than we are?
I read a short story about that very thing. It all started with a scientist cloning a Neanderthal, just as this article describes.
The idea in the story is that Neanderthals were much smarter than the Cro-Magnon men, but could could not survive the Ice Age due to their higher dietary requirements that came from being so large and muscular.
However, once Neanderthals were introducted into modern society with little resource scarcity, they started outcompeting modern man, taking all the best university slots, etc. The story was leading to another confrontation between us and them, and the Neanderthals intended to win this time.
