I wonder if the muscle attachments from bone to muscle were anchored in different locations compared to modren humans.

I think that's true. Humans have pretty tall attachments compared to most animals. Tall gearing is better for endurance running and for throwing.

Neanderthals had knobbier, more robust skeletons. They were more adapted for cold weather and less for running all day across the grasslands. The wave of modern types out of Africa that replaced them was probably better with the throwing spear among its advantages.

Can you recommend a book or article with more information on this? It's an idea I've been tossing around & would like to read more about.
