Summary Introduction
To determine: The ways that molecular evidence has refined the animal phylogenic analyses.
Introduction: Animal kingdom exhibits vast diversity. The evolutionary history of the organisms is represented by a phylogenetic 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.
