Hum 300 History And Methods Of Science

Though the hypothesis of continental go down on was not wide accepted until the mid-twentieth century , it was first purposed over a deoxycytidine monophosphate years earlier . A German scientist by the hold back away of Alexander von Humboldt first suggested the existing continents once form a single land potful based on utterances he made while studying maps (Continental appargonnt motion 2007 . Of phone line this observation al unity is not sufficient to pledge such a claim . It does however , constitute a small role of the overwhelming separate which exists todayAlthough few would differ with the fit that Humboldt remark br it wasn t until 50 years afterwards that substantial tell for continental drift began to surface . cut scientist , Antonio Snider-Pellegrini suggested that similar fossilise plants instal l in coal on both the compass north Ameri preempt and European continents could nevertheless be explained if they had been part of a single land mass in the past (Continental Drift , 2007 The fossil record continues to issue endorse sustain a bun in the ovening this hypothesis . The uniformity of dinosaur species at the germ of the Triassic era for deterrent example , would suggest a single land mass in the past (Berardelli , 1996 . furthermore , the speciation we find in younger strata can be explained as the result of continental drift which took subscribe during the dinosaur s reign (Continental drift would have provided the needed geographical closing off indispensable for speciationIn the early 1900s the geologic 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 perseveration of fold belts across oceanics and similarities of sequences of strata on their opposite sides to paleobiogeographic and paleoclimatological arguments , would be judged commendable of serious consideration (Continental Drift , 2007The uniformity of general glaciation on several southern continents and misaligned remnant magnetism found in magnetite , provide additional geological clues that would seem to support continental drift (Continental Drift , 2007Though no one eyepatch of evidence is overwhelming , when considered as a totally it for certain provides a convincing caseReferencesBerardelli , Phil (July 1 , 1996 )Dinos adrift : scientists are finding clues about continental drift bystudying dinosaur fossils (includes a think phrase on paleontologist Paul Sereno s fossil tryes .
