Question
Chapter 20.1, Problem 3C
Summary Introduction
To determine: Whether a population following concept of biological species will also follow morphological species concept.
Introduction: In the ancient times, various plants and animals were defined by their external features like morphology and structure. However, the introduction of the concept of biological species concept by Ernst Mayer provided the base for universal classification of organism into specific species. The morphological concept of species is based on simple morphology and sometimes in special cases helps to classify organisms left out by biological species concept.

At some point in the past, species A resided as a large population entirely within a rectangular geographical area. The population became divided into two isolated populations when, during a major earthquake, a mountain range arose and disrupted gene flow. Over time, the two new populations evolved independently from one another, yielding species B and C. The population comprising species C became divided into two isolated populations when another earthquake created an escarpment that disrupted gene flow. Over time, these two new populations evolved independently from one another, yielding species D and E.Imagine that you were to arrive to the region long after species D and E had evolved, completely oblivious to the scenario that is described above; survey the region for living species in this group; and conduct a cladistic analysis on those species.
