Asynchronous evolution of mammalian myosin proteins. The matrix illustrates the normalized distances between corresponding sequences. Asynchronous evolution is observed if the pattern of the deviation from the mean is different. For example, the pattern from rat to the other mammalian species is very similar, illustrating their synchronous evolution in general. However, there are differences in the patterns of some class-I myosins between rat and mouse and opossum, indicating their asynchronous evolution. In contrast, the sequence comparison patterns of cow and the other mammals are very different, indicating the asynchronous evolution of all cow myosin genes. The abbreviations for the organisms are: Rn, Rattus norvegicus; Mm, Mus musculus; Pat, Pan troglodytes; Hs, Homo sapiens; Mam, Macaca mulatto; Caf, Canis familiaris; Bt, Bos Taurus; Md, Monodelphis domestica.
