Is "directional selection" really a "mechanism" of natural selection? Isn't the whole point of natural selection is that it always favors adaptive traits? What form of "natural selection" is not "directional?" I know that biologists use the term "directional," but I always thought that they used it somewhat colloquially, so general audiences understood the import of natural selection -- OR in order to develop precise mathematical models of specific directions in evolution. In this case, "directional selection" is at best a way of describing natural selection or a form of natural selection (sill want to know the other forms), not a "mechanism." Also, we need to work on the style ("a lot" is not really proper and apropriate to an encyclopedia) Slrubenstein

Balancing selection, diversifying selection, purifying selection etc stc DJO 14:42, 15 February 2007 (UTC)

Directional Selection, Disruptive Selection, and Balancing Selection (from what I've read) are instances of Microevolution. It seems to me that all three of these articles could be merged with or incorporated into the Microevolution article, which also seems lacking. Cypher227

I thought the peppered moth example had been recently 'disproven'? merv

[edit] Categorization

This article (along with its two listed neighbors: Stabilizing selection, Disruptive selection), seems somewhat lost in the wider Category:Evolutionary biology memeplex. It needs better folding in, and that larger group needs better navigability amongst its related pieces. - Rgrant 20:32, 29 May 2006 (UTC)
