A curious perspective on The Evolution of Evolution, this Discovery Magazine story analyzes the initial posting and subsequent changes to the "Evolution" entry on Wikipedia. More than anything it attests to the true power of wikipedia in balancing out potentially biased authors, thereby weathering "edit wars".

the site was "altered 2,081 times by 68 editors between December 2001" and October 2005.
(As a side issue, my youngest son and I both agree that the graph reminds us of the southwest border of the U.S.)
