:::Philip, I noticed your comment regarding your doubt about the information I introduced into the article - just wanted to respond. Microevolution is defined as evolution at a level that is below the species - it does not involve speciation, but shifts in allelic frequencies due to the environment, mutation, or some other event. I have the utmost confidence in this. I'll provide a reference at my earliest convenience as I am about to leave for work. Cheers. [[User:Wisdom89|Wisdom89]] 09:45, 28 November 2007 (EST)

:::: What I'm questioning is not whether microevolution is ever defined as evolution below the species level, but whether everybody agrees on that definition.  I've been under the impression that many people simply define it rather vaguely as a "small" change as distinct from a "big" change.  Also, has anybody actually defined microevolution as being equivalent to a change in gene frequency, or are they simply ''similar'' concepts.  If what you are saying is correct, it therefore seems that "evolution", often now defined as a change in gene frequency, is therefore ''defined as'' microevolution, which means that ''macro''evolution is not evolution!  [[User:Philip J.
