Chapter 13, Problem 2WIO
Summary Introduction
To determine:
The types of information used to hypothesize the relation of species to one another by the descent from a shared ancestor and to give an example that includes multiple types of evidence supporting each other.
Concept Introduction:
The descent with modification is the term for the summated processes of the evolution. This implies that the present species have descent from the common ancestors with the modifications caused by the environmental factors for the survival. This results in the diversification of the species, which is visible at the present time.

Does the use of DNA sequences in the study of evolutionary relationships mean that other characteristics are unimportant in such studies? Discuss what other forms of evidence you may still want to use, along with when and why those other forms of evidence would be especially helpful.
Use the shapes below to answer Question number 2. Please be accurate and complete it CORRECTLY. Don’t use previous answers.
Phylogenetic trees are a type of model that can be used to show how organisms are related through common ancestry. The phylogenetic tree model represents nodes numbered 1 through 8.
Using evidence from the phylogenetic tree determine which species would be MOST closely related to the species on branch C?
Question options:
The species on Branch A is most closely related to the species on branch C because they share the most recent common ancestor at node 1.
The species on Branch B is most closely related to the species on branch C because they share the greatest number of common +ancestors.
The species on Branch A & B are both most closely related to the species on branch C because they share the most most recent common ancestor at node 2.
The species on Branches F, G, H, and I are all equally related to the species on branch C because they all split from a common ancestor at the same time which is illustrated by having nodes 2 and 7 at the…

- Using the phylogenic tree below, answer the following questions: 1 -Species A -Species B -Species C -Species D -Species E -Species F Which species will shares only one characteristic with the others? Which numbered location identifies characteristics shared by Species E and F? Which species will share characteristics similar to those at location 3? Which numbered location indicates a common ancestor of all the species on the tree?arrow_forwardWhat are the types of evidence and procedures that can be used to establish evolutionary relationships?arrow_forwardWhen constructing phylogenetic trees, what is the purpose of applying maximum parsimony? Parsimony allows the researcher to "root" the tree. For trees based on morphology, the most parsimonious tree requires the maximum evolutionary events. The outgroup roots the tree, allowing the principle of parsimony to be applied. For trees based on morphology, the most parsimonious is the one that uses the simplest explanation of evolutionary events.arrow_forward

Provide examples for each of the barriers.arrow_forwardDiscuss how the principle of parsimony can be used in a cladistics approach to constructing a phylogenetic tree.arrow_forwardUse the data matric provided to draft a phylogenetic tree.

A cladogram is a diagram that shows relations among organisms. A cladogram uses lines that branch to end at groups of organisms with a common ancestor. The image shows the relationship among groups A, B, and C. Closely related organisms will have one or more SHARED TRAITS, indicated by the green and orange circles. 1. Which two organisms are most closely related? 2. The green dot indicates a trait that is shared by every animal on the diagram. Suggest a trait that would apply. 3. Animals A & B share a trait that animal C does not have, indicated by the orange circle. Suggest a trait that would apply.

- When presenting a phylogenetic tree, researchers will often indicate the level of bootstrap support for each clade. This is done by placing a percentile number along the branch leading to that clade, as in the figure above. Here, the number 80 indicates that the - A. the outgroup is a monophyletic clade in 80% of the bootstrap replicates. B. the ingroup is a monophyletic clade in 20% of the bootstrap replicates. C. the outroup is a monophyletic clade in 20% of the bootstrap replicates. D. the ingroup is a monophyletic clade in 80% of bootstrap replicates.arrow_forwardDraw a possible unrooted tree that is the most parsimonious and use the table to do so. Explain why the tree is designed the way you designed it. Be sure to use appropriate language in your explanation such as most recent common ancestor, sister taxon, ingroup/outgroup, reversal, etc.arrow_forwardCladistics Exercise: The following is a chart demonstrating the shared derived traits among several clades of animals. The row across the top represents the animals, the column on the left represents a trait. An X in the box shows which animals have the particular trait, and which do not. Take out a piece of paper and draw a diagonal line. Then add the nodes and draw in which species drop off at each node. In other words, construct a cladogram for this chart. Then take a picture of the cladogram and upload it to complete this assignment.
