When you think of cavemen, you probably think of large, ape-like people who harmed others for the fun of it. Barbaric monsters that would eat a child’s brain if they looked at them funny.

You may compare them to the way medieval people treated those with dwarfism. They viewed them as demonic entities who could only work as clowns, or entertainment for the higher ups in society. Or you may think of the Spartans who killed any imperfect child. Even Aristotle supported these practices. He once stated that there should be a law that kept any imperfect child from being able to live.
