The current version is nothing short of inane. It can't even get the creationist canards correct. For example, the claim is made that no known mechanism adds "genetic material" - this is so false it isn't even funny. Many forms of mutations add genetic material. Examples include polyploidy, single-bit insertions and  gene duplications. The claim made is that no mechanism adds "information" or a new "function" Note that even this claim is woefully false. Examples include: Negoro, et al. "The nylon oligomer biodegradation system of Flavobacterium and Pseudomonas" Biodegradation 5: 185-194 which discusses bactera that through a mutation became able to digest nylon.

:I will continue when I have the chance on the edit.  I am on lunch right now.  Tsumetai is correct in that neutral evolution does not mean a lack of change in the phenotype, an example in laymans terms, hair color is a neutral change in the phenotype.  A single neutral change does not have an impact on the speciation but it is the accumilation of these phenotype changes that makes the difference and thus the impact on speciation.  That is why neutral evolution is considered a mech. of macroevolution. --[[User:Tims|TimS]] 12:51, 14 April 2007 (EDT)
