CREATION BY EVOLUTION 



would not all be purely transient, disappearing with the next 

 generation; some of them would be hereditary; they would 

 persist in later generations. The descendants of the origi- 

 nal single individual would become diverse — hereditarily 

 diverse. From a single individual, from a single race, we 

 should thus, after the passage of many generations, get 

 rmany races that would be hereditarily diverse. 



In a human lifetime or in many human lifetimes we could 

 not expect these changes to be great. Geological time is 

 enormously long and evolution is prodigiously slow. The 

 doctrine of evolution would therefore not lead us to expect 

 to see widely diverse creatures produced. The popular 

 demand that we should see a cat, or the offspring of a cat, 

 transformed into a dog, or an amoeba into a vertebrate, is 

 not in accord with the doctrine of evolution. We cannot 

 expect in a lifetime to see new "species" produced. All that 

 the doctrine of evolution leads us to expect is that there 

 should appear slight hereditary changes, so that from a single 

 race there are produced a number of hereditarily diverse 

 races, differing slightly. 



Do we find this? Studies of this sort have been made 

 of a number of organisms. What was found in such a study 

 made by the present writer may be set forth as a type. 



It is common to suggest that amoeba or some amoeba-like 

 creature is the original stock from which animals descended ; 

 "from amoeba to man' is a common phrase. It is of interest 

 to examine amoebas from this point of view. Are amoebas 

 still transforming, producing other kinds of animals.^ Some 

 of the amoebas are naked and formless, so that the detection 

 of any slight hereditary changes would be almost impossible. 

 Others have shells of definite form and structure, furnishing 

 excellent opportunity for the detection of hereditary altera- 

 tions. These shelled amoebas, though they closely resemble
