Talk:Preadaptation

	Evolutionary biology portal This redirect is part of WikiProject Evolutionary biology, an attempt at building a useful set of articles on evolutionary biology and its associated subfields such as population genetics, quantitative genetics, molecular evolution, phylogenetics, and evolutionary developmental biology. It is distinct from the WikiProject Tree of Life in that it attempts to cover patterns, process and theory rather than systematics and taxonomy.

Copyvio[edit]

The first revision of this article seems to have been split off from the Wikipedia article "Gradualism". Its "ibid" refers back to a work cited on that page. The "copyvio" template was misplaced, as http://encyclopedia.thefreedictionary.com/ is a mirror of Wikipedia. --rbrwr ^± 20:35, 7 Mar 2005 (UTC)

I had previously put the copyvio tag on the page and I agree with Rbrwr's analysis. I wikified the article and put the proper source in this article as well (to prevent further confusion). Rl 07:55, 8 Mar 2005 (UTC)

Lead weakness[edit]

I added some See Alsos and wikilinks to articles I had to scan in order to understand this one.
In the Lead, the explanation that "a species evolves to use a preexisting structure" needs to be expanded/clarified. E.g. What is a 'structure'? What are some "pre-existing" structures (e.g. vestigial, cryptic variation, hitchhiker, so-far-unexpressed mutation, ????) which might be brought into play?
The phrase "potentially unrelated function" is vague/abstruse. Please concretize more. Fascinating topic, and understanding evolves, for "lay" readers like me, when ideas are more bodied out. The dinosaur and arthropod examples are helpful! Twang (talk) 20:36, 3 June 2011 (UTC)[reply]

Exaptation and Preadaptation[edit]

In the introduction, I think that the use of feathers is more of an exaptation than a preadaptation. — Preceding unsigned comment added by Doug carragher (talk • contribs) 17:45, 7 December 2012 (UTC)[reply]
