Response Article
This article (Peppered moths occur in uncamouflaged colors in many areas (Talk.Origins)) is a response to a rebuttal of a creationist claim published by Talk.Origins Archive under the title Index to Creationist Claims.


Claim CB601.2:

Various aspects of the change in frequencies of the varieties of peppered moth and their geographical distribution are inconsistent with its proposed explanation in terms of natural selection resulting from differential predation.

CreationWiki response:

It needs to be noted that the traditional peppered moth story is no way a threat to creation science. Not only do the peppered moths remain peppered moths but there has not even been a change in the peppered moth gene pool—only a temporary shift in populations. The fact that Evolutionists even consider this evidence for evolution is a sign of desperation.

1. The claim is based on the naive assumption that local observations of differential predation rates are sufficient to make accurate predictions of the relative frequencies of the different varieties of peppered moth. It also falsely insinuates that early attempts to explain these phenomena relied exclusively on visually selective predation to the exclusion of all other factors.

Wells was not making predictions of the relative frequencies of different peppered moth varieties. His point was that there are other factors besides natural selection at work, and these observations show that to be the case.

In fact, I am not aware of any evolutionary biologist who has ever suggested that natural selection resulting from differential predation would by itself account completely for all details of the geographical distributions of the peppered moth's varieties, or of their change in relative frequencies.

While this is true, one does not get that impression from the traditional peppered moth story. Wells was using the local observations to make this exact point.
