If you are in class Mammalia, the caseins certainly mutate at a rapid clip. There are (ca.) 37 entries in PIR last time I checked. These include a number of different types of caseins, related only name. However, one could probably make a number of parallel trees of the class which would, if nothing else, make an interesting exercise. --------------------------------------------------------------------------- TTGATTGCTAAACACTGGGCGGCGAATCAGGGTTGGGATCTGAACAAAGACGGTCAGATTCAGTTCGTACTGCTG Eric E.
