Talk:Directional selection

message: 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

message: 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)

message: This page is quite vague and could use a bit more information. Alongside that, the illustration is poorly executed and does not explain the process. Andrew Colvin (talk) 23:15, 25 November 2009 (UTC)

message: The disambiguating page for positive selection refers the reader to this page for discussion in an evolutionary context, but that term is not even mentioned here except as reference titles. See also negative selection. Billfalls (talk) 14:24, 7 May 2010 (UTC)

message: Hello! 
I took out the indication that directional selection was a specific type of negative natural selection. I think that both positive selection and negative selection could both apply here based on what allele was being looked at, and found the sentence a little misleading. Does anyone disagree with this choice? Thanks! 
I also edited some information in the second paragraph stating that if directional selection happened on a recessive allele it would become fixed in the population. Although this could potentially be true, I found the statement falsely affirming that this WOULD happen. Again, let me know if I'm wrong! I linked a source that led me to believe it was a potential but not assured. 
Another question: I believe that positive selection should not direct viewers to specifically here. What do others think?
