Highlight the node (branch point) that represents the most recent common ancestor of A and B. b. Which species is the outgroup? Highlight the one: A B C D E F G c. Which species have trait 1? Highlight all who do: A B C D E F G d. Which species have trait 2? Highlight all who do: A B C D E F G e. Which species is/are most closely related to E? f. Which species is/are most closely related to F?

(a) Draw a phylogenetic tree based on the characters in the table below. Draw hatch marks on the tree to indicate the origin of characters $1-6 .$ (b) Assume that tuna and dolphins are sister species and redraw the phylogenetic tree accordingly. Use hatch marks to indicate the origin of characters $1-6 .$ (c) Determine how many evolutionary changes are required in each tree. Identify the most parsimonious tree.
