  1. Your Inner Fish by Neil Shubin Leonie Cohen Chapter 7 – Adventures in Bodybuilding

  2. Bodybuilding • Body = parts work together • Division of labor (a.k.a. “Cambrian explosion”) How? Why? Why so long? ?

  3. Cells: Sticking and Communicating • “Stick” (pages 127,128) • Molecular rivets • Collagen - ECM • “Talk”(page 128) • Molecular signals http://wiki.pingry.org/u/ap-biology/index.php/Extracellular_matrix http://hodnett-ap.wikispaces.com/Chapter+11+Cell+Communication

  4. Choanoflagellates [koh-uh-noh-flaj-uh-leyts] (pages 132-135) • 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 Pages (137,138) • Why? • Predator vs. prey • Importance of size • Why so long? • Cost • Increased oxygen – “Oxygen Catastrophe” # of Billion Years Ago http://en.wikipedia.org/wiki/Great_Oxygenation_Event
