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 confusedwith "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 thetwo trees below best represents the phylogenetic relationship between species shown in the nucleotidedivergence plot above (top tree or bottom tree)?ABCD EhumansE-HСн/ D-HВ-нА-НEDс в АhumansA-HC-H / B-HD-HE-H Give the stratigraphic arrangement of rock layers as shown below, the circles represent places wherefossils were found. Match the fossil with the fossil collection site (put the collection site number in theblank on the answer sheet). Assume the level 4 is where you find the extant species A, B, C, D, E, andhumans.8.(736.(57. 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 thefollowing fossil deposits:Site 2- rich in ancient fish fossilsSite 3- rich in lungfish and coelacanth-like fossilsSite 6- contains T-rex and various other dinosaursSite 8 - saber tooth tigers and ground slot fossilsWhich site would you expect to find a therapsid fossil?C) site 7B) site 5A) site 4

6) One could apply the phylogenetic species concept by a.comparing the morphology of two organisms. b.tracing the common ancestry of two organisms. c.determining the overall similarity in the ecological niche of two organisms. d.mating two organisms to see if viable offspring result.
To construct a phylogenetic tree by applying the principles of parsimony to molecular sequence data, one would: a. start by making assumptions about variations in the rates atwhich different DNA segments evolve. b. group together organisms that share the largest number ofancestral sequences. c. group together organisms that share derived sequences, matching the groups to those defined by morphologicalcharacters. d. group together organisms that share derived sequences, minimizing the number of hypothesized evolutionarychanges. e. identify derived sequences by studying the embryology of theorganisms.
In a cladistic analysis, a systematist groups together organisms that share: derived homologous traits. derived homoplastic traits. ancestral homologous traits. ancestral homoplastic traits. all of the above.
What is the difference between micro- and macroevolution? Microevolution describes the evolution of small organisms, such as insects, while macroevolution describes the evolution of large organisms, like people and elephants Microevolution describes the evolution of microscopic entities, such as molecules and proteins, while macroevolution describes the evolution of whole organisms Microevolution describes the evolution of organisms in populations, while macroevolution describes the evolution of species over long periods of time Microevolution describes the evolution of organisms over their lifetimes, while macroevolution describes the evolution of organisms over multiple generations.

1) How have scientists created the "tree of life"? Do you think that variations exist between these created trees? 2) What are the pros and cons to creating a "tree of life"? 3) When constructing this tree of life we can see many dead ends or organisms that we are unsure of their exact placement. Why is this? 4) Choose one species (either alive today or extinct) and describe its taxonomic classification. What traits or characteristics were used to classify this species into its current taxonomic classification? What other organisms are considered to be its closest relatives?
