In 1996, at the tail end of the 20th century, a biochemist named Michael Behe published a book in which he reveals an idea that he describes (in a fit of uncharacteristic humility) as only being one of the greatest scientific discoveries of the last 100 years (cue triumphant music). It really is an amazing idea; amazing because it points scientists to God. (Disclaimer: does not necessarily point scientists to God. *wink*)
This amazing idea was apparently less amazing when it was first presented to the world eighty years earlier by someone else. Perhaps because that older version was (ironically?) more correct. I'll get to that later.
