Homework Answers
Answer. Option 1
Observe carefully that the parsimonious tree 3 and 4 are exactly similar to each other.
Here in option 2 and 3, A and B clades are more closely related with D being the outgroup. Means option 4 also shows the same.
But in option 1, A and C clades are more closely related that is why it is different from the other three options.

10. Which of the following statements describes a purpose for which biologists use phylogenetic trees? a. For human diseases once found only in other animals, phylogenetic trees are helpful in determining when and where the infectious organisms first entered human populations. b. Phylogenetic trees are useful for determining how many times a particular trait may have evolved independently within a lineage. c. Phylogenetic trees can be used to reconstruct ancestral traits. d. Phylogenetic trees can be used in conjunction with...

Analysis based on two individual genes (gene trees) may imply two different phylogenetic relationships among a group of species. List three possible reasons for this (1), and explain how one of them works (2). If only one phylogenetic tree accurately represents the true evolutionary history of these species, what might we do in order to determine which one is correct (2)?

Which of the following represents a conflict between phylogenetic trees estimated from morphological data versus DNA sequence data? a. choanoflagellates are the closest living relative of animals b. protostomes and dueterostomes are a fundamental split within the bilateria c.sponges are the most ancient, or basal, lineage of animals d. body cavities evolved in the following order : acoelomate, pseudocoelomate, coelomate

these trees can show how similar or different species are from
each other. the vertical line on the left is the start and how far
to the right each sequence is from the left line or a branch point
indicates increasing dissimilarity. so if your sequence is close to
the the left line it is similar, but if it is at the end of a long
arm on a branch and falls to the right it is less similar.

Phylogeny is the evolutionary history of a species. a) Cytochrome C is an important mitochondrial protein found in most organisms. The table below indicates the number of similarities in the amino acids found within Cytochrome C compared across five different species. Based on the data in the table, draw a phylogenetic tree that reflects the evolutionary relationships of the organisms based on the differences in their cytochrome c amino acid sequence. Based on the data, identify which species is most...

Monotremata Marsupialia Assume the mammal cladogram on the right depicts accurate evolutionary relationships. While there is no absolute time on this cladogram, there is relative time running from left to right (right is more recent). Answer the following questions about this tree. Afrosoricida - Macroscelidea Tubulidentata Proboscidea Hyracoidea Sirenia Xenarthra Dermoptera 1. Monotremes (Monotremata) are the only mammals (extinct or extant) that do not give live birth. Based on this information and this tree, what type of group are mammals...

3. According to the molecular sequence-based phylogenetic tree of animal life, which of the following is correct? a. Eucolomate animals evolved from pseudocoelomate animals, which in turn evolved from acoelomate animals. b. Segmentation probably evolved in only one clade, which includes more than one phylum showing segmentation. C. Segmentation evolved in some protostomes and some deuterostomes. d. Deuterostomes are more closely related to eucoelomate protostomes than to other protostomes that are pseudocoelomate or acoelomate. e. None of the above is...

How do biologists use the parsimony method when constructing a phylogenetic tree? If there is only one true evolutionary history for any group of species, discuss the possible reasons why the taxonomists analyzing genetic data (e.g., DNA sequence data) versus those analyzing morphological data may suggest different phylogenetic relationships among the same exact group of species? 4) Describe how the agnathans differ from other fish? Compare the morphology and natural history of hagfishes and lampreys. Your answer should include (at...
