Response Article
This article (Over-specialization with no adaptive value sometimes occurs (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 CB950:

Evolution says that complex structures would not be formed without a selective advantage for them. But overspecialization with no adaptive value sometimes occurs. An example is the enormous antlers of the Irish elk. Despite the seeming disadvantages, animals with such extreme features seem to do as well as other animals.

CreationWiki response:

Talk Origins has a good point on this claim; however it is not commonly used, and would seem to only be used by the cited source.
