The problem of course is that Darwin didn't write any of his books until long after the Fathers were dead.
David Barton is just a liar.
The Right's Favorite Historian: Founding Fathers Opposed Darwin | Mother Jones
Talk to a prominent social conservative these day and the odds are pretty good that he or she is a fan of David Barton. Perhaps more than any other person, the Texas-based amateur historian has provided grist for the idea of American Exceptionalism—the argument that America's unique success in the world is divinely caused and due to its committment to core Judeo-Christian principles. Minnesota Rep. Michele Bachmann, the tea party champion and likely 2012 presidential contender, invited him to teach members of Congress about the Constitution; former House Speaker Newt Gingrich says he learns something new every time he listens to Barton.
He's a pretty influential guy. So what, exactly, does he teach? On Wednesday, Right Wing Watch flagged a recent interview Barton gave with an evangelcial talk show, in which he argues that the Founding Fathers had explicitly rejected Charles Darwin's theory of evolution. Yes, that Darwin. The one whose seminal work, On the Origin of Species, wasn't even published until 1859. Barton declared, "As far as the Founding Fathers were concerned, they'd already had the entire debate over creation and evolution, and you get Thomas Paine, who is the least religious Founding Father, saying you've got to teach Creation science in the classroom. Scientific method demands that!" Paine died in 1809, the same year Darwin was born.
