evolution when only the mean time of family formation is considered. Accordingly, for assessing the feasibility of the formation of the largest families under a given model, the coefficient of variation of the formation time should be taken into account. As shown above, this coefficient is quite large (>100 for all considered genomes) such that the actual formation time of the largest family could differ from its mean value by two orders of magnitude or more, which would bring the time required for the formation of families of the observed size close to realistic spans of ~ 109 yrs. In order to investigate this problem further, we turned to computer simulation analysis.

Figure 13. Dependence of the time (in years,Ga) required for the formation of the largest family on the model degree dfor the rational BDIM. The plot is in semi-logarithmic coordinates. The model parameters are for D. melanogaster (blue), C. elegans (violet), H. Sapiens (red) and A. thaliana (green). A color version of this figure is available online at http://www.Eurekah.com.
