because rates of molecular evolution can vary significantly among organisms. However, there has been a general reluctance to abandon the molecular clock entirely, because it represents such a ...

Molecular evolution is the area of evolutionary biology that studies evolutionary change at the level of the DNA sequence. It includes the study of rates of sequence change, relative importance of ...

The changes and variations in genetic code that occur over time are referred to as "molecular evolution." The molecular evolution of an organism can be very different from its morphological (body ...

In my view, this indeed applies to the field of molecular evolution, a position with which others appear to agree (R. Kaufman, The Scientist, May 3, 1993, page 1). Along with the Journal of Molecular ...

Research in the Copley lab centers on the molecular evolution of catalysts and metabolic pathways. Enzymes in metabolic pathways are superb catalysts, accelerating chemical reactions by up to 16 ...
