6. (top or bottom) Species A, B, C, D, and, E are all extant species (living today, not to be confused with "extinct" species). Consider the common ancestor shared between humans and species A (ancestor A-H), the common ancestor between species B and humans (ancestor B-H), etc. Which of the two trees below best represents the phylogenetic relationship between species shown in the nucleotide divergence plot above (top tree or bottom tree)?

Question

I need help answering these questions for these figures. I'm not sure how to interpret it. 

6. (top or bottom) Species A, B, C, D, and, E are all extant species (living today; not to be confused with "extinct" species). Consider the common ancestor shared between humans and species A (ancestor A-H), the common ancestor between species B and humans (ancestor B-H), etc. Which of the two trees below best represents the phylogenetic relationship between species shown in the nucleotide divergence plot above (top tree or bottom tree)?

Give the stratigraphic arrangement of rock layers as shown below, the circles represent places where fossils were found. Match the fossil with the fossil collection site (put the collection site number in the blank on the answer sheet). Assume the level 4 is where you find the extant species A, B, C, D, E, and humans. 8. (7 3 6. (5 7. A-H ancestor (choose between sites 2 and 3) 8. E-H ancestor (choose between sites 2 and 3) 9. Putting aside species A-E, let us say that the following layers in this stratigraphic diagram have the following fossil deposits: Site 2- rich in ancient fish fossils Site 3- rich in lungfish and coelacanth-like fossils Site 6- contains T-rex and various other dinosaurs Site 8 - saber tooth tigers and ground slot fossils Which site would you expect to find a therapsid fossil? C) site 7 B) site 5 A) site 4
