A constantly cited problem in Darwin’s observations is the idea that he established his theory, primarily, on his observations of variation in domestic animals and domestic plants. It has been my goal to find a sure basis for the theory in the variations of organisms in a state of nature. While the accurate amount and exact nature of these variations is of paramount importance in the various problems that arise when we utilize the theory to explain the facts of nature, it’s essential to show the actual variations as they are found to exist in a sufficient amount of species. In doing so, we not only gain a better and more precise estimate of variation, we obtain a groundwork of fact by which to examine the assertions and objections usually put forth on the issue of specific variability. I will make clear that, throughout the work, I refer to to the charts and the facts they illustrate, just as Darwin tended to appeal to the facts of variation among dogs and pigeons.

I have also made what seems to me a decisive change in my treatment of the matter. Rather than treat first the relatively and unfamiliar details of variation, I will begin with the Struggle for Existence, which is in truth the important process on which natural selection depends. Then I will detial with the particular facts that are relatively familiar and very intriguing. My analysis has the further advantage of looking widely at how natural selection plays in natural environments.

I do admit that my observation contains divergences from some of Darwin’s perspectives, but my work tends to exemplify the terrific importance of Natural Selection over all other agencies in the creation of new species. I therefore take up Darwin’s early position, which he changed in the later versions of his works. The fact of natural selection and its influence on the mutation and development of species is the Darwinian doctrine, and on that account, I am a devout advocate of pure Darwinism.

It’s interesting to note the outgrowth of scientists of the Christian faith who embrace intelligent design theory. Their theory lies somewhere between the purely Biblical opinion of creation theory on the one side and Darwin’s theory of evolution. There is a fascinating genre of evolution humor appearing in the last few years.
