Use the following phylogenetic tree to answer a series of questions.  Consider the following cladogram of eight species of Mimulus (M.).  Note that the time vector is pointing to the left in this diagram, so the current species are on the left and the ancestors are on the right hand side.  A. What do nodes represent? B. Which species is most closely related to M. lewisii ?  C. How do you know ? D. Which species would be the outgroup ?  E. What was the pollinator for the common ancestor to the eight species shown here ? F. How many times did pollination by hummingbirds evolve in this clade ?
