| traloids, Papuans and Melanesians as being descended from them. Prior to the acceptance of continental drift, biologists frequently postulated submerged landmasses in order to account for populations of land-based species now separated by barriers of water. Similarly, geologists tried to account for striking resemblances of rock formations on different continents. The first systematic attempt was made by Melchior Neumayr in his book Erdgeschichte in 1887. Many hypothetical submerged land bridges and continents were proposed during the 19th century, in order to account for the present distribution of species. 237 As Lemuria gained some acceptance within the scientific community, it began to appear in the works of other scholars. Ernst Haeckel, a German Darwinian taxonomist, proposed Lemuria as an explanation for the absence of "missing link" fossil records. According to another source, Haeckel put forward this thesis prior to Sclater (but without using the name 'Lemuria. Locating the origins of the human species on this lost continent, he claimed the fossil record could not be found because it had sunk beneath the sea. Other scientists hypothesized that Lemuria had extended across parts of the Pacific oceans, explaining distributions of species across Asia and the Americas. The Lemuria theory disappeared completely from conventional scientific consideration after the theories of plate tectonics and continental drift were accepted by the larger scientific community. According to the theory of plate tectonics (which is nowadays the only accepted paradigm in geology, Madagascar and India were indeed once part of the same landmass (thus accounting for geological resemblances, but plate movement caused India to breakaway millions of years ago, and move to its present location. The original landmass broke apart - it did not sink beneath the sea level" -- Reference Wikipedia.org back to 127) Download 2 Mb. Share with your friends:
