He went on to define a distinctly democratic and American way of doing science, according to historian Naomi Oreskes. By the s, Chamberlin was the dean of American science and his colleagues fawned that his originality put him on a par with Newton and Galileo.

Rollin T. For decades afterward, older geologists warned newcomers that any hint of an interest in continental drift would doom their careers. Wegener took the assault as an opportunity to refine his ideas and address valid criticisms. When critics said he had not presented a plausible mechanism for the drift, he provided six of them including one that foreshadowed the idea of plate tectonics.

When they pointed out mistakes—his timeline for continental drift was far too short—he corrected himself in subsequent editions of his work. But even he would have been astonished by the charges against the Italians for failing to turn continental drift into a predictive device; that trial is expected to continue for months.

Wegener's final revison cited supporting evidence from many fields, including testimonials from scientists who found his hypothesis resolved difficulties in their disciplines much better than the old theories.

Climatology was one such discipline. Fossils and geologic evidence show that most of the continents used to have startlingly different climates than they do today. Wegener thought continental drift was the key to these climatic puzzles, so he and Vladimir Koppen plotted ancient deserts, jungles, and ice sheets on paleogeographic maps based on Wegener's theory. Suddenly the pieces of the puzzles fell into place, producing simple, plausible pictures of past climates.

Evidence of the Permo-Carboniferous ice-age era that peaked some million years ago, for example, was scattered over almost half the Earth, including the hottest deserts. Wegener considered such paleoclimatic validation one of the strongest proofs of his theory. Conversely, continental drift has since become the organizing principle of paleoclimatology and other paleosciences. This slideshow explains Wegener's theory. Wegener's theory. Earth around million years ago.
