THE COMMON HOUR

GAME 10. Please come prepared with information from last week. The categories will be TAXONOMY, ANATOMY, PHYLOGENY.  As before, much of this information comes from the data sheets, Margulis & Schwartz (1998), Holt & Nelson (2001), The Origin (chapter 10), cultures, slides, and preserved specimens from the last week of class.   You may bring a CLEAN taxonomy with you and use it in the game.  You may use nothing else.
