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
