By use of two-dimensional electrophoresis of a cell’s rRNA a ‘fingerprint’ of the cell can be produced. This "fingerprint" indicates the existance of a large difference between what has been termed "prokaryote" and "eukaryote". In fact, some select groups of organisms thought to be prokaryote are no more prokaryote than eukaryote. Thus three "primary kingdoms" have been proposed by evolutionists for these basic cell types. Such a strong difference in the reproduction system of these three cell types indicates that any evolutionary history would have to be at a simple level with an extremely early divergence. As a result of this, the evolutionary model for the cell must consist of three coexisting paths rather than the classical single pathway. In view of this a creation model would appear to fit more precisely with available data.
