Aw c'mon...this is an easy one. The compartment in the skull where the cerebellum sits is significantly larger in Neandertals than modern humans, and the places on the bones where the muscles insert are also larger, denoting more muscle mass (their bones were 30% more robust also).
Elementary, my dear Watson.
Some other stuff that evolutionists say may be humbug, but you picked the wrong example here: these are facts.
