Did snakes and lizards lose their legs at the same time?

What are the evolutionary advantages of having a forked tongue?

Forked tongues are an amazing evolutionary advantage if you use your tongue in the same way a snake does. Snakes don’t have ordinary tongues – they “see” using a sensory organ in the mouth called the Jacobson’s organ (I think it’s called that – you might want to look it up to be sure).

Why do snakes have fork tongues?

If you guessed because it makes them look bad apples, you’d only be half right. The reason snakes have forked tongues is because they use them to “smell.”. By flicking its tongue in the air, a snake can collect odor-causing particles that it then delivers to a sensory organ in its mouth.
