The latest issue of Nature contains the following paper.

   Gorr, T., Kleinschmidt, T. and Fricke, H. (1991) Close tetrapod 
   relationship of the coelacanth Latimeria indicated by haemoglobin
   sequences. Nature 351, 394-397.

The paper looks at the evolution of globin genes in a number of organisms
including coelacanth. It is evident that these genes have not stopped evolving
in the line leading to the modern coelacanth. This is the sort of evidence
that many of us have been referring to when we point out that lack of
morphological change over a long period of time does not mean that evolution
stops.
