The paleobotanist Dan Axelrod wrote a number of papers on how the
distribution of fossil plants proved that the continents had not changed
position. Then for several years he wrote no biogeography papers at all,
and then he came out with a paper showing how the distribution of fossil
plants supported continental drift. He never would call it "continental
drift", though; always insisted on calling it "continental rafting".
