Chins are a human-only club. That’s right, we are the only animals on Earth with a true chin—the bony knob that juts out from the bottom of our face. So, the next time you’re scratching your dog’s “chin,” you’re actually just rubbing its jawbone. A true chin is a unique, protruding lump of bone, and it’s a feature that even our ancient ancestors, like Homo erectus, and our primate cousins, like gorillas and chimpanzees, never got in on.
