Molecular information for taxa that have a good enough fossil record is used to calibrate the " clock , " which can then be used to estimate the time since divergence for pairs of taxa that have an inadequate fossil record ( see Chapter ...

As with phenetic measures of overall morphological similarity , these distance measures will correlate with time since divergence only if the rate of divergence is approximately constant . Hence the question is raised of whether or not ...

Divergence in protein function We have noted throughout this book instances in which the properties of a protein are altered by changes in amino acid sequence . Divergence in the sequence of genes that arose by gene duplication is also ...
