It must be pointed out that the interactive local stretching and compression of the LUT-an essential feature of the Fua et al method-cannot be implemented here (obviously impracticable on a printed document!). For that reason, a comparison between ColorPhylo and the Fua et al algorithm from the present figures exclusively would be highly unfair. However, there are noticeable differences between Figures 5 and 6 . A high diversity in the population of birds from Lesser Antilles and Puerto Rico could be inferred from figure 6 right insert, whereas it is not supported in fact by the evolutionary tree (Fig. 6 , left insert). Moreover, the high difference between birds
