The Molecular Clock and Evolutionary Rates Across the Tree of Life ...

WebMolecular evolution in general—and the molecular clock in particular—offered little basis for exploring evolutionary causation. According to the molecular clock hypothesis, proteins evolved essentially independently of the environmentally determined forces of selection; this was sharply at odds with the panselectionism prevalent at the time. WebA história da evolução molecular começa no início do século XX com a "bioquímica comparada", mas o campo da evolução molecular só se tornou independente durante as décadas de 1960 e 70, seguindo o aparecimento da biologia molecular. O advento da sequenciação de proteínas permitiu que biólogos moleculares criassem comparação de ...
