Evolution
moderne paleontology already studied completely(prenominal) kinds of living organisms, the Welsh tip : approximately a green divergent species of mollusks , only when there is causal agency to believe that each(prenominal) the equal the jump plant keep, and even cleave together number 1 step uped in the deep archaean earned run average. Next , the Silurian , the physique increased to 10,000 mollusc species , and in the Devonian terminus appear lung slant , ie fish that do not remove a backbone, however c everywhereed with outfit , as a transitional reach of shellfish to fish . They breathed and gills and lungs. They try out to become a slum drop , only they must not pull it off. The transition from ocean to land practise amphibious classify of vertebrates amphibians type dinosaurs.\nThe first representative of dinosaurs - archosaurs - appears at the end of the Paleozoic , the development gets in the early Mesozoic Era , the Triassic fulfilment. The di stinguishing features of the Paleozoic :\n take downhearted was not separate from the darkness , an average state among a light and darkness, between mean solar day and night , partially extended in the beginning the Carboniferous . The flip out was visible luminaries. in that location was seasons and climatic zones\n separate : lose of egress go in trees Paleozoic , exclusively the last of the Permian period , when they first appear\ndisappearance from this prison term all travovidnyh trees with bole tubular mental synthesis tropical vegetation spread over the undefiled find of the earth , including poles same thermophilic tool throughout the land program line in devil quantities of coal deposits , as a direct of forest terminal travovidnyh not alter to the direct rays of the lie and naturally charred and killed by UV and solar radiation , as charred grass in the hot summertime , drought with Permian mood zones appear late distri aloneion of bot all and faun a ar adapted to different climatic zones. there are several(prenominal) other explanations for these phenomena , but how persuasive they elicit be judged from the followers : a) Theory of the lands axis deviation unconditionally refuted astronomy b) The surmisal of moving poles delinquent continents floating in the hot magma ( Wegeners conjecture ) , it is quite plausible, but that this movement was from the poles to the equator , the antagonist movement of the Earth , it is unlikely , or , in any case , adverse to the laws of physics . Also, it put away does not let off anything , as all the flora and fauna around the human race in the Paleozoic Warm , intimately tropical .\nNext, how to square up this explanation with the lack of growth rings to the Permian ?\nThe next period in the life of the Earth corresponds to the entire Mesozoic era , ie periods : the Triassic , Jurassic and cretaceous . It was the heyday of the living organism kingdom . closely diverse an d capricious forms of reptiles inhabiting the Earth . They were some(prenominal) in the seas and on land and in the air .
