Summary:

• **Snakes Are Evolving to Eat Other Snakes**: Scientists have discovered that some snake species are slowly evolving to become cannibals, meaning they eat other snakes of their own kind. This is happening because snakes that can eat other snakes have an easier time finding food, so they survive and have babies that inherit this trait.

• **Why This Evolution Happens**: When snakes live in areas where their normal food (like mice or lizards) is hard to find, snakes that are brave enough to hunt other snakes can still get meals and stay alive. Over many generations, more and more snakes in these populations develop the ability and instinct to hunt their own kind.
