Chapter 21.2, Problem 3R

Summary Introduction

To review:

The two traits which have evolved along the same branch of the reconstructed phylogeny.

Given:

The matrix which is given shows the traits of seven land plants and an aquatic plant which is the out of the group of land plants. The traits are given in the form of + or –, which is given when the traits are present or are absent, respectively.

Introduction:

Phylogenic reconstruction is a method to reverse the model of evolution. It describes the relationship between the evolutions of the relative of common ancestors. So, the scientists use the phylogenic reconstruction to know the common traits which are present in the taxa given.
