Competition may explain why males have more robust skulls and brow ridges
Neanderthals were heavily built and muscular, with projecting faces, large teeth, low foreheads, heavy brow ridges
, and chinless jaws.
Although her skull had the prominent brow ridges
, low forehead, and protruding lower face that would have made her unusual-looking to modern eyes, the structure and size of the rest of her body was very similar to ours.
The skull also has prominent brow ridges
, which are a distinctly human hallmark not seen outside our own genus, or species family, Homo.
Characteristic features of these hominids include thick bones, sloping foreheads, bulging brow ridges
, chinless jaws, and peg-shaped front teeth.
