a)   Draw a phylogenetic tree based on characters 1-5 in the table below.  Place 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)       How many evolutionary changes are required in each tree?  Which tree is most parsimonious? Use figure 20.5 and 20.12 from the Campbell, Biology in focus. Can you pls explain this to me?

Examine the image of the relatedness of vertebrates represented in this phylogenetic tree. Which statements are correctly inferred from this tree? Select all that apply.   A) The mammals are the outgroup in this tree.     B) Birds and dinosaurs share a recent common ancestor.     C) Mammals and birds are more closely related than any other species.     D) Turtles are equally as diverged from lizards and snakes as they are from crocodiles.     E) Lizards and snakes are more recently diverged from each other than they are from crocodiles.

For the first phylogenetic tree, if we assume absolute time is NOT represented, can we say that the species in circle B are more closely related than the species in Circle A? For the second phylogenetic tree (if we hold the same assumptions), can we say that B and C are more closely related than A and C?

Sketch the generated phylogenetic tree below and color the branches of the generated phylogenetic tree according the the island: 1) Anolis sheplani 2) Anolis cybotes 3) Anolis olssoni 4) Anolis celestinus 5) Anolis occultus 6) Anolis cristatellus 7) Anolis puchellus 8) Anolis evermanni Hispaniola Species - Blue Puerto Rico Species - Red 1) What can you conclude about the relatedness of anole lizards living on these two islands?
