Earthworms are often thought of as lowly, insignificant, simple organisms. The truth is, they are biological wonders capable of serious environmental impact. On this episode, Macken answers the following questions about earthworms:

- If you cut a worm in half, do both halves live on?

- Can they reproduce with themselves?

- What is that band for?

- Why was Charles Darwin so fond of worms?

- Did Darwin experimentally determine what a worm's favorite food is?

- Why is this animal called the common earthworm, if they aren't that common compared to other earthworms?

- How come they carry leaves back to their den?
