Dodson reduces the number of genera from 540 to 285, with 336 species. A little less than half these genera are each represented by single specimens, and skulls are unknown for about the same proportion. Presuppositions of science as related to origins. The importance of presuppositions in doing science is the subject of this paper. Mills lists four presuppositions that seem to be accepted by most scientists.
Sense perceptions are valid.
All events can be explained in terms of natural processes. Mills accepts the first three points, but takes exception to the last one. The origin of the universe and the origin of life have not been satisfactorily explained by natural processes, and in fact appear to require processes different from those observed at present. Because of this, Mills would substitute two other presuppositions for the fourth point listed above. Nearly everything else can be explained in terms of natural processes.
