It’s been a while since I’ve studied it, but IIRC skeletons of early humans show in general more traits we view as masculine, like stronger chins and a more jutting brow line, even in female skeletons. It was even more pronounced in male skeletons, but this is still pretty mild sexual dimorphism even among great apes (think male vs female gorillas, for example).

Why did you have to remind me?

This is from the movie about the making of Battlefield Earth with John Travolta played by Val Kilmer
