I have a horrible feeling he's not going to be far off, LDC. Those numbers seem a little high, based on things I've read, but only a little. Getting the precise methodology of the survey will be important before we enter anything into the article.
Sidenote: I don't think this needs to be a separate article. Verified numbers, when and if found, should be included in the main article(s), and this "evolution poll" should be canned. Good place for it now, while we sort out the facts, however. - MMGB
