Not everything has an evolutionary advantage. Sometimes things just *are*. There is a species of pig whose tusk curves backwards, can’t be grinded down and ends up stabbing them in the head, growing through their skull and killing them. There’s no reason for this. No benefit. It just *is*. We aren’t immaculate beings of design, we’re random products of natural selection. A scientific phenomenon, an organism. Nothing more.
