I see the uncanny resemblance 'tween Shimon Perez, JRoth, Epstein (lesser degree) to the Peru Skull.
There is no way to enlarge the brain cavity, but you can deform the skull when very young. I don't know either way if they had their skulls intentionally deformed when young or are just deformed. And they are deformed; I always was creeped out by them and thought they looked wrong, but couldn't put my finger on why, so thank you.
Zuckerberg also looks wrong, but in a different way (yes, Data, I know, but there's something else IDK). There are others as well.
