The animal kingdom is full of weird specializations and features. A mutation happens and suddenly an animal has a different color, or a new feature. A stronger jaw, a higher top speed, you name it. Specializations are caused by little errors in the DNA of an individual. Most of these changes go completely undetected, but sometimes they’re very evident. More often than not this mutation doesn’t change much about the animal, but when it does it either means the demise of this animal, or success. And when success hits, this specific animal will likely be able to have more offspring than it’s other species members.
