E. Zuckerkandl and L. Pauling (1962), Molecular disease, evolution and The assumption of this methodology is that the similarities between genomes of organisms will help to develop an understanding of the taxonomic relationship among these species.

The aim of this review is to introduce the important terminology and general concepts of tree reconstruction to biologists who lack a strong background in the field of molecular evolution. CiteScore values are based on citation counts in a range of four years (e.g. Molecular phylogenetics allows more precise tests: species relationships can be more accurately known and information on the timing of speciation allows us to focus on the most recent events. The Evolution of Molecular Biology: The Search for the Secrets of Life provides the historical knowledge behind techniques founded in molecular biology, also presenting an appreciation of how, and by whom, these discoveries were made. MEGA is an integrated tool for conducting automatic and manual sequence alignment, inferring phylogenetic trees, mining web-based databases, estimating rates of molecular evolution, and testing evolutionary hypotheses.
