Evolution

History of the undercoat, since the expression of organic deportment on it forrader the advent of universe upon it , is divided into terce main periods - the era , which protest sharply from one a nonher, and is know as : Paleozoic - ancient animation sentence. Mesozoic - mean , Neozoy - a new aliveness . Of these, the largest at the clock - the Paleozoic , it is sometimes divided into 2 parts : archean and imprinter(a) Paleozoic , as astronomic , geological, climatic and floristic conditions differ sharply from the late early . The freshman ar: the Cambrian , Silurian and Devonian periods , the second - and Permian ember .\nPrior to the Paleozoic era was early , yet because at that place was no life.\nThe first life on flat coat - is algae and plants in general . initiative algae originated in irrigate: so represents the first coming into court of the modern scholarship of organic life , and only by and by mollusks that feed on algae.\nAlgae are lamenta ble into the soil deceive , ogre grass moving in the trees travovidnye Paleozoic.\nIn the Devonian period, the mankind appears profuse vegetation , and wet - in the form of life of its sm bothest representatives : the simplest , trilobites , etcetera Warm humour - each(prenominal) over the globe , for on that point is still a modern thumb with its sun, moon and stars , everything was cover with a three-ply , low semipermeable , powerful defile of water evaporation , even in an enormous design of surrounding country , and only a portion of the water settled in ocean basins .\nEarth hurtles cold world space , but because she was dressed(p) in a warm, impenetrable shell. collectable to the greenhouse ( conservatory ) effect all the Early Paleozoic , including even the carbonous period , a warm-water flora and wolf in all the earth , and on Svalbard and Antarctica - everywhere deposits of burn , which is the product of the rainforest , everywhere was warm-water maritime fauna . whence the suns rays do non penetrate forthwith on the drop anchor , but refracted through a know angle pairs and then covered her other than than it is now : the darkness was not so dark and not so foresighted , and the day is not so talented . Night were shorter straightaway . in that location was no winter or summer , there is still astronomical and geophysical reasons for this. blacken deposits consist of trees , without ingathering rings of a tubular bodily structure , like grass and not nib . So , the seasons were not. There was no climatic zones , also due to the greenhouse effect.
