#2: No-Knuckles
As far as mutations go, this one is relatively common, but nonetheless, it’s still bizarre. I’m sitting here trying to understand what it would feel like to have one less knuckle in my fingers, and I’m having a hard time imagining it. I mean, how does it even work?
These are the kinds of things that seem confusing to the average person, purely because we’re not used to it. If everyone walked around without knuckles in their hands, then this would be completely normal, and everyone would know the appropriate way to move their hands.
