Hum 300 History And Methods Of Science

Though the surmisal of Continental err was not enormous accepted until the mid-twentieth century , it was first purposed over a 1 C years earlier . A German scientist by the human body of Alexander von Humboldt first suggested the existing continents at a time formed a exclusive land peck ground on notes he made while studying maps (Continental prepare 2007 . Of course this observation al unitary is not sufficient to wear such a claim . It does however , constitute a small append of the overwhelming proof which exists todayAlthough few would protest with the fit that Humboldt mention br it wasn t until 50 years posterior that substantial shew for continental drift began to surface . french scientist , Antonio Snider-Pellegrini suggested that similar ossified plants undercoat in coal on both the northwestern Ameri typeset forward and European continents could take into accountd be explained if they had been part of a single land mass in the past (Continental Drift , 2007 The fossil record continues to provide tell supporting this hypothesis . The uniformity of dinosaur species at the get of the Triassic era for compositors case , would suggest a single land mass in the past (Berardelli , 1996 . Furthermore , the speciation we reckon in younger strata can be explained as the resolving power of continental drift which took put up during the dinosaur s reign (Continental drift would return provided the needed geographical isolation required for speciationIn the archean 1900s the geological evidence began to mount .

Alfred Wegener , a German meteorologist , put together an impressive list of geological evidence which he presented in 1912 (Plate Tectonics , 2007 Concerning Wegerer s contributions , it has been notedEven today his evidence , ranging from the continuity of sight belts across oceans and similarities of sequences of strata on their opposite sides to paleobiogeographic and paleoclimatological arguments , would be judged worthy of earnest consideration (Continental Drift , 2007The uniformity of general glaciation on some(prenominal) southern continents and misaligned remnant magnetism found in magnetite , provide additional geological clues that would await to support continental drift (Continental Drift , 2007Though no one piece of evidence is overwhelming , when considered as a substantial it certainly provides a convincing caseReferencesBerardelli , Phil (July 1 , 1996 )Dinos adrift : scientists atomic number 18 finding clues about con tinental drift bystudying dinosaur fossils (includes a helper article on paleontologist Paul Sereno s fossil lookes .
