Ever heard of a little concept in biology called "Bilateral Symmetry"? It's the reason you have two arms and legs that are mirrors of each other rather than just one limb on the top and bottom of your body. It's the reason you have two eyes and ears, two nostrils, etc. The vast majority of animals have the gene that contains the trait for it - insects, mammals, reptiles, birds, micro-organisms, etc. The dinosaurs and THEIR ancestors had it. It's a gene that old.

Having two animal ears or two horns and counting it as one trait works because of bilateral symmetry. Without the gene governing this trait, the whole of our genetic make-up would be so wildly different and complicated I'd be surprised if we (and anything we could create based off us) could possibly exist.
