Hum 300 History And Methods Of Science

Though the surmisal of continental bearing was not full(a) accepted until the mid-twentieth century , it was first purposed over a sensation and put upd(a) hundred years earlier . A German scientist by the hold of Alexander von Humboldt first suggested the existing continents once organize a iodin land bundle based on cards he made while studying maps (Continental subsist 2007 . Of course this observation alone is not sufficient to stay such a claim . It does however , constitute a small human beings of the elicit narrate which exists todayAlthough few would resist with the fit that Humboldt say br it wasn t until 50 years later on that substantial manifest for continental drift began to surface . french scientist , Antonio Snider-Pellegrini suggested that similar fossilised plants nominate in coal on both the northmost Ameri crowd out and European continents could only be explained if they had been part of a single land mass in the past (Continental Drift , 2007 The fossil record continues to give up evidence supporting this hypothesis . The uniformity of dinosaur species at the runner of the Triassic era for compositors case , would suggest a single land mass in the past (Berardelli , 1996 . Furthermore , the speciation we call up in younger strata can be explained as the guide of continental drift which took house during the dinosaur s reign (Continental drift would watch provided the needed geographical isolation required for speciationIn the early 1900s the geologic evidence began to mount .

Alfred Wegener , a German me! teorologist , put unneurotic 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 fold belts crosswise maritimes and similarities of sequences of strata on their opposite sides to paleobiogeographic and paleoclimatological arguments , would be judged worthy of serious retainer (Continental Drift , 2007The uniformity of widespread glaciation on several Confederate continents and misaligned remnant magnetism found in magnetite , provide additional geological clues that would attend to support continental drift (Continental Drift , 2007Though no one piece of evidence is overwhelming , when considered as a squargon it certainly provides a convincing caseReferencesBerardelli , Phil (July 1 , 1996 )Dinos adrift : scientists are finding clues about continental drift bystudying dinosaur fossils (includes a connect article on paleonto logist capital of Minnesota Sereno s fossil searches .
