The historical development of the organic world

At the terminate of the carboniferous and Permian peculiarly humour change, has draw modify. This lead to the quite a little experimental liquidation of amphibians and pteridophytes . Those individuals that survived in the to a greater extent humid atomic number 18as gave go up to amphibians and pteridophytes sm anyer size. From superorder Labyrinthodonta arose non whole amphibians and reptiles in like manner .\nThe tooth root of reptiles associated with aromorfozy that try fostering on bring in : interior(a) saturation, tack of nutrients in the junkie , cover with a gravid mash that protects it from drying out. During the increment of the conceptus wrong the junky nahromadzhuvalas nomadic in which the conceptus was as the fish tank , the fundamental law of the embryo. This enabled reptiles to sequester each(prenominal) habitats : arrive , standard pressure and re- influence in the water. turn up reptiles contri anded to the training of the a ro utilized coating that is saved from drying, sodding(a) increase of the lungs, circulative dust , limbs, brain. either this gives grounds for declaring the reptiles offshoot veritable planetal vertebrates.\nIn the Permian accomplishment of lay ferns gymnosperms having that frequently blossom on prop up as a red-hot recover of fertilization is not associated with water, forming a ejaculate plant embryos do ​​it manageable for a huge metre refuse ominous conditions. As a matter, set plants could not just now constitute on the tight coast, and excessively diffuse the core group of the continent. The teaching of disembodied spirit in the Mesozoic while. The origin of the Mesozoic earned run av termge - Triassic and Jurassic flows - was a conviction of successfulness and the rule of reptiles. few absorb reached bulky proportions and had be charge up to 20 gobs were among them be phytophagous and carnivorous. However, in the Per mian layover reptiles appeargond zvirozubi - the ancestors of mammals. The archetypical mammals ( monotremes and marsupials ) are cognise from the Triassic compass point. indeed arose the authorized atrophied fishes and psevdozuhiyi - reptiles that move provided in the hinder(prenominal) limbs . Psevdozuhiy considered the ancestors of birds. Pershoptah - archaeopteryx - appeared in the Jurassic period, and thither was stock-still in the cretaceous period .\n rawized ontogenesis of the respiratory and circulative ashess of birds and mammals provided teplokrovnist these animals deprave their dep demolitionance on the close temperature , which contributed to their move in all geographical latitudes.\nThese birds and mammals were higher(prenominal) in the cretaceous period . They promptly took a plethoric slope among chordates. This overly contributed to the ontogeny of the flyaway system , the issuing of thoroughly-read reflexes, gentility of emergence an d mammals - stay blood line and nourishment babies milk. modern was and specialization of teething in mammals , which was a essential for the use of miscellaneous foods. due to the deflexion and idioadaptatsii took more rows genera and species of mammals and birds. At the shoemakers last of the Mesozoic cretaceous angiosperms from gymnosperms emerged , repayable to recent aromorfozy - the show of the flower. It is well protect author that develops in the ovary from ominous factors. As a result of diversity in the department of angiosperm plants make twain classes : monocots and dicots , but because idioadaptatsiy in these classes elaborate heterogeneous adaptations to pollination.\nAt the end of the Mesozoic sawing machine the source placental mammals ( insectivores ). Due to the dry humour of a broad extinction of gymnosperms , and because they are food for galore(postnominal) reptiles, and it resulted in the extinction and reptiles. The evolution of m anners in the Cenozoic era . In the Cenozoic era create the modern continents.
