Chapter 33.3, Problem 3EQ
Summary Introduction
To determine: The impact that the revision in nematode and arthropod phylogeny has had in the area of research.
Introduction: Animal kingdom exhibits vast diversity. The evolutionary history of the organism is represented by a phylogeny tree. The phylogenetic tree shows the evolutionary relationship between different species. Phylogenetic trees were earlier based on the morphological features of the organism. However, the development in molecular biology in the past decade has made major revisions to many phylogenetic tree data.
