This is a method of "inferring the divergence of time of clades from a common ancestor by means of gene/protein sequencing" and has been termed 'molecular dating'. The process is one in which there is a calibration of time in comparison to the Phanerozoic era fossil data and then expoliation is conducted for providing the estimation time for divergence of phyla. (Sukumaran, 2004; paraphrased) Indeed, if life did evolve as posited in the work of Charles Darwin then "the abrupt appearance of diversified life at the beginning of the Cambrian period was not explainable." (Sukumaran, 2004) However, Sukumaran explains that gradualism is not a central tenet to the idea that there has been an evolution of...
