Summary Introduction

To describe: The results obtainedby Cooper and colleagues after the comparison of sequences of DNA.

Introduction: The differentiation or classification ofthe species on the basis of evolutionary relationships between the organisms is called “cladistics.”By usinga cladisticapproach, the characters which are shared or not shared between a number of species can be representedin the form of a phylogenetic tree.

Summary Introduction

To determine: The proposed phylogeny of flightless birds affected by the results of the study.

Practice Portfolio Activity, Part 1 Five species of Xenite-an imaginary animal-have been found on a planet in another solar system. Based on the order of the rock layers in which fossils were found, species A appears to be the oldest and probably the most primitive. There is no evidence to support the relative age of the other species of Xenite. A в с Be the evolutionary biologist, and complete the following activities to build a cladogram of Xenites. a. spines b. eyestalks c. tail D d. mouth 1. Create a table noting which species of Xenite has each characteristic below, marking each as yes or no. E 2. Study your table, and figure out the order of evolution of each character. You have been given reason to believe that, based on the fossil record, Xenite A is the ancestral species. For the Xenites, consider what appear to be homologies and analogies. Create your cladogram for the Xenites. You may upload a picture of a drawing of your table and your tree using the image box.
