For many of you, yesterday was the first day you have dissected a preserved organism in order to observe its component structures and learn about its anatomy first-hand. An early nineteenth century anatomist, Xavier Bichat, claimed that once you "open up a few corpses... you will dissipate at once the darkness which observation alone could not dissipate." Before modern technologies, the only understanding scientists and doctors had of bodies--human or otherwise--was derived purely from observation and dissection. Reflect upon your experiences during the dissection today. What were your expectations or anticipations for the lab? What did you see that was familiar, and what did you see that was foreign or unexpected? What do you now understand about earthworms that you did not understand before? What parallels can you make between the anatomy of an earthworm and your own anatomy? Use your answers to the laboratory questions to guide you as you write. Your response should be 2-3 paragraphs' worth of writing.
