Chapter 25, Problem 2COQ
Summary Introduction
To describe:
The use of systematics in proposing the phylogenetic tree and the basis behind using parsimony’s principle in the evaluation of such a tree.
Introduction:
The study of diversity among the biological creatures and the evolutionary relationships between the organisms of extant and extinct species is called systematics. Systematics also plays a critical role in finding the relationship between the organisms on the basis of their characteristics.
