Another Molecular Phylogenetic Analysis Technique

Abstract

P. Joseph Antony Reneese

Molecular phylogeneticsis that the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominately in DNA sequences, to realize information on an organism's evolutionary relationships. From these analyses, it's possible to work out the processes by which diversity among species has been achieved. The results of a molecular phylogenetic analysis is expressed during a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the utilization of molecular data in taxonomy and biogeography.

Molecular phylogenetics and molecular evolution correlate. Molecular evolution is that the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches within the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise thanks to molecular evolution and leads to the development of a phylogenetic tree. The figure displayed on the proper depicts the phylogenetic tree of life together of the primary detailed trees, consistent with information known within the 1870s by Haeckel.
