![]() ![]() That might seem surprising now, but most people didn’t believe it…they called it a startling, improbable idea.’ ‘in general, it went over like a lead balloon. But the lack of physical evidence for the theory meant it was generally met with skepticism.Īntonio Snider-Pellegrini's Illustration of the closed and opened Atlantic Ocean (1858)Įven after Fred Vine and Drummond Matthews presented physical evidence that continents drifted in 1963, citing magnetic strips that appear symmetrically around mid ocean ridges, there was still widespread disbelief. He wasn’t the only one – by the time Alfred Wegener presented the theory of continental drift to the German Geological Society in 1912, he was crediting several others with having proposed similar ideas. Here, as with inheritance, Darwin suffered from being too far ahead of his time, hypothesising ideas which he needed 21st century tools to prove. He is clearly onto the fact that there is some sort of ‘motive force’ under the surface which is driving these changes. “it may, I think, be considered as almost established, that volcanos are often (not necessarily always) present in those areas where the subterranean motive power has lately forced, or is now forcing outwards the crust of the earth, but that they are invariably absent in those, where the surface has lately subsided or is still subsiding” “Do the areas which have subsided, as indicated by the presence of atolls and barrier-reefs, and the areas which have remained stationary or have been upraised, as shown by fringing-reefs, bear any determinate relation to each other and are the dimensions of these areas such as harmonize with the greatness of the subterranean changes, which, it must be supposed, have lately taken place beneath them? Is there any connection between the movements thus indicated, and recent volcanic action?” His hypothesis that the circular reefs are formed by coral forming on a volcanic island, then growing upwards as the island subsides beneath it, was widely accepted but not proven definitely until the 1950s.įrom 'The structure and distribution of coral reefs' 1842 In his brilliant 1842 monograph on the structure of coral reefs, Charles Darwin proposes, among other things, a theory for how coral atolls are formed. Researching the early history of continental drift often brings up Ortelius’ name but, surprisingly, another scientist who was on to the idea years before a mechanism was established is rarely mentioned. “the vestiges of the rupture reveal themselves, if someone brings forward a map of the world and considers carefully the coasts of the three ”. ![]() “torn away from Europe and Africa…by earthquakes and floods” Way back in 1587 the Flemish cartographer Abraham Ortelius wrote in Thesaurus Geographicus that the Americas were ![]() Abraham Ortelius 1527 - 1598 (Rubens, 1633)Ĭontintental drift, on the other hand, has been around for a surprisingly long time. ![]()
