Molecular paleontology
Molecular paleontology refers to the recovery and analysis of DNA, proteins, carbohydrates, or lipids, and their diagenetic products from ancient human, animal, and plant remains. The field of molecular paleontology has yielded important insights into evolutionary events, species' diasporas, the discovery and characterization of extinct species. By applying molecular analytical techniques to DNA in fossils, one can quantify the level of relatedness between any two organisms for which DNA has been recovered.Advancements in the field of molecular paleontology have allowed scientists to pursue evolutionary questions on a genetic level rather than relying on phenotypic variation alone. Using various biotechnological techniques such as DNA isolation, amplification, and sequencing scientists have been able to gain expanded new insights into the divergence and evolutionary history of countless organisms.
