 and muscle of different animals, with high and with low concentrations of

Kaplan et al. state, in summary that: 



The data presented indicate that it is possible to classify animals not 

 only by their physiological and morphological characteristics but also 

 by their enzymatic properties, and they also suggest that change in 

 enzyme structure may have been of significance in the establishment 

 of new species. 



Boser and Pawelke (1961) have discovered that there are two 

 mahc dehydrogenases in potato. This finding is pertinent to Kaplan's
