Table 2 Application of different estimators of location to data sets from a molecular clock study [8]. Each column in the table corresponds to a different evolutionary branch point, between various groups of fungi and plants, being timed; data from the first two columns are shown in Figure 6. Individual data points are divergence time estimates (millions of years ago) from constant rate proteins (number of proteins in parentheses). Time estimates in bold are those obtained with the two preferred estimators.
