Many workers have previously devoted attention to the contribution of errors in measurements to the problem of building trees from distances, as summarized in the contribution by Marshall.25 By contrast, we have not been concerned with this relatively minor source of error. Instead, our concern has been with a bigger source of error, the calibration error, which reflects the uncertainty in the relationship of distance measured with an indirect method to that measured with a more direct method. This aspect has not been addressed by previous workers. To illustrate the magnitude that this problem can assume, we note that DNA hybridization led to an estimate of 3.3% sequence divergence between the mitochondrial DNAs of two flies (Drosophila yakuba and D. teissieri).26 Restriction analysis done on the whole mitochondrial genome, in contrast, led to an estimate of 0.22%.27 Sequencing of one-seventh of these fly mitochondrial DNAs produced an estimate of 0.3%,27 similar to the latter indirect estimate but in dramatic contrast to the estimate from hybridization.
