Chapter 23.3, Problem 3LO
Summary Introduction
To determine: The meaning of phylogenetic species concept and the reason that it is controversial.
Introduction: The concept of a phylogenetic species as a significant group, the members of the groups is decreased from a common ancestor. Also, they maintain a combination of specific defining or derived traits. So, the concept describes a species as an assembly that has shared and is a remarkable evolutionary history.
