title: Globin evolution in some species of the genus Bufo.
abstract: The globins of 10 species of toads of the genus Bufo have been analysed. From the values of the reciprocal rates between their amino acid residues a 'dissimilarity matrix' was made. In this have been included the values related to Discoglossus pictus and Xenopus laevis. The numerical data, derived from a computer program, gave a dendrogram representing the evolution of the analysed globins. This appears correlated to the geographical distribution and to the metabolic adaptation of the corresponding species of Bufo more than their chronological appearance.
