Examine the following phylogenetic tree illustrated in Figure shown in the first picture.
In general, what does a phylogenetic tree illustrate?
How do you compare the relationships of organisms BB, CC, and DD?
Given the following organisms in the Table in the second picture, number them in terms of which is relatively closest and distant. Number 1 refers to closest.
Draw a simple phylogenetic tree for two sisters clades with a common ancestor. Each sister clade consists of two taxa. Define the following terms and use to label your diagram: clade, node, branch, common ancestor, and taxon.
Referring to the phylogenetic tree shown above, answer the following questions:
1. How many OTUs are included in the phylogenetic analysis?
2. How many clades are there?
3. What is an autapomorphic trait of the domestic cat? Explain why?
4. What is the shared derived trait (synapomorphy) in the Family Felidae? Explain why?

- What is the difference between a cladogram and a phylogenetic tree? Given a cladogram for a group of species, what additional interpretation is needed to obtain a phylogenetic tree?arrow_forwardA cladogram used in a comparison of morphology among taxa had equal length branches, but when looked at in a blast webpage using the given gene sequence, the branches all had different lengths. Why is that?arrow_forward(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 thetwo trees below best represents the phylogenetic relationship between species shown in the nucleotide divergence plot above (top tree or bottom tree)?arrow_forward
- Below is a phylogenetic tree. Which of the following statements is correct? Species C and D are called sibling taxa because both are derived from the same parent species H. Species F is more related to species K than species D is. Species A, B, and D share a common ancestor of species I. All species shown are currently with us.

- Below is an example of a particular kind of phylogenetic tree called a chronogram. Chronoograms are named because the length of the branches represents different lengths of time. Nodes are represented by vertical lines, and branches with horizontal ones. They can be arranged horizontally, with the most recent evolutions on the right. Given this information, the taxa that is most closely related to Dubautia ciliolata c. 529 (highlighted below) is _________________ (make sure to type exactly the same characters, including the numbers; do not italicize).arrow_forwardShown above are three possible phylogenetic trees for species I, II and III reconstructed based on the 4-nucleotide DNA sequences given in the righthand table. In every tree, each hatchmark on a branch represents a single base-change event. The most parsimonious tree would be - A. Both X and Y. B. X. C. Y. D. Both Y and Z. E. Z.arrow_forwardFor novice biologists, taxonomy and phylogenetics are difficult concepts to understand and keep separate. This confusion is made worse because modern taxonomic methods make use of molecular tools. Write an essay that contrasts taxonomy to phylogenetics and explain how both disciplines are important to our understanding of species and evolution. Your essay should include a description of taxonomy and phylogenetics, as well as a detailed explanation about how information is represented in a phylogenetic tree or a cladogram.arrow_forward
