4 Choanoflagellates [koh-uh-noh-flaj-uh-leyts]
(pages ) Single-celled microbes DNA of choanoflagellate ≈ DNA of sponge The potential of single-celled organisms: Catching prey  rivets, attachments Molecular interactions communication Importance?

5 Development of Bodies Why? Why so long? Predator vs. prey Cost
