Bones of at least fifty Neanderthal humans have been found, but never a complete skeleton. We have virtually all the parts. With left-right doubling and comparing bones from different specimens, the American Museum of Natural History assembled the first complete model of a Neanderthal skeleton a couple of years ago. It’s on display in the Hall of Man.
The model enabled them to see clearly that the Neanderthal had a flaring ribcage, broader at the bottom, and a flaring pelvis opening up more at the top. I wonder if they carried a broader belly?
