Molecular evolution is the process of change in the sequence composition of cellular molecules such as DNA , RNA , and proteins across generations. The field of molecular evolution uses principles of evolutionary biology and population genetics to explain patterns in these changes. Major topics in molecular evolution concern the rates and impacts of single nucleotide changes, neutral evolution vs.

Techniques in molecular systematics and evolution

The comparative and evolutionary analysis of molecular data has allowed researchers to tackle biological questions that have long remained unresolved. The evolution of DNA and amino acid sequences can now be modeled accurately enough that the information conveyed can be used to reconstruct the past.

In general, molecular systematics provides a powerful statistical framework for hypothesis testing and the estimation of evolutionary processes, including the estimation of divergence times among taxa. The field of molecular systematics has experienced a revolution in recent years, and, although there are still methodological problems and pitfalls, it has become an essential tool for the study of evolutionary patterns and processes at different levels of biological organization.

This review aims to present a brief synthesis of the approaches and methodologies that are most widely used in the field of molecular systematics today, as well as indications of future trends and state-of-the-art approaches.

Molecular Systematics

Cody W. Edwards, Robert D. Phylogenetic relationships among 15 individuals representing 6 subspecies of Neotoma mexicana from the United States and Mexico were examined using DNA sequences from the mitochondrial DNA cytochrome b gene. Parsimony, likelihood, and genetic distance analyses revealed a dichotomy between populations of N. A 2nd dichotomy existed between wood rats in the Sierra Madre del Sur in southwestern Mexico and those south of the Isthmus of Tehuantepec.

It seems that you're in Germany. We have a dedicated site for Germany. The amount of information that can be obtained by using molecular techniques in evolution, systematics and ecology has increased exponentially over the last ten years. The need for more rapid and efficient methods of data acquisition and analysis is growing accordingly. This manual presents some of the most important techniques for data acquisition developed over the last years. The choice and justification of data analysis techniques is also an important and critical aspect of modern phylogenetic and evolutionary analysis and so a considerable part of this volume addresses this important subject. The book is mainly written for students and researchers from evolutionary biology in search for methods to acquire data, but also from molecular biology who might be looking for information on how data are analyzed in an evolutionary context.
