Question
Chapter 30, Problem 1IQ
Summary Introduction
To explain: The reason why a phylogenetic tree based on comparison of a single gene could result in an inaccurate hypothesis.
Introduction:Amborella is a monotypic genus of small trees endemic to the Grande Terre of New Caledonia. Amborella is of great interest for plant systematists. This is because molecular phylogenetic analysis consistently places it as the sister group to all other flowering plants.

- Can you construct a phylogenetic tree for the following?arrow_forwardPhylogenetic 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…arrow_forwardProvide details of a mechanism that can result in the creation of new genes, with novel functions, that may contribute to the evolution of new species.
