Talk:Directional selection

From Wikipedia, the free encyclopedia

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

[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)
