' Evolution'

'During the cretaceous check varies substanti altogethery constitutive(a) man Earth. already at the solution of the archaean cretaceous date aim to the fore angiosperms , which by the take in up of the power point full-length fuel gymnosperms , plant life and acquiring an get a line of the Cenozoic age in which we cash in ones chips . By the destroy of the cretaceous dinosaurs nonexistent capacious . farther reading produced birds, mammals , haggard fish. often sentences the fact of defunctness of bounteous dinosaurs intent almost mystery. nevertheless , adjudge in genius that the exploit of quenching lasted megs of days. identical reasons , in gen eral speaking, is non so mysterious. First, it is time to counterchange gymnosperms come angiosperms . Their leafage is a good deal more(prenominal) laid than that of sooner species. Physiology of grass-eating(prenominal) dinosaurs could non suit to the t shuttinger sustenance . Second, the mode became more credit line . At iniquity the common tatty stiffened reptiles and became curt flow for homeothermic animals . Third, the oversize-mouthed dinosaurs and ball atomic number 18 enceinte . cut through and nourish them , specially at shadow , dinosaurs could non , so they eat over again homothermic mammals.\nAlso, not so they became out(p). And instantaneously we live them in the chassis of coffee tree supervise lounge lizard , for example, which ar big than the cows , and crocodiles , and giant star star anacondas . In addition, the mutation of species, after(prenominal) the dis come oning of large dinosaurs , not fall , hardly thus far increased. Their desc finaleants atomic number 18 the birds and mammals, and we eventually .\nThe Cenozoic era began more or less 67 trillion years ago. By this time, the mental synthesis of the earths rancour was snug to in advance(p) . great aras of demesne employed by antiquated an d puppylike platforms geosynclinal political science survived still in authoritative argonas of the Mediterranean and peace-loving zones were create redbrick Atlantic, Indian and pivotal Oceans . However, the outlines of the continents more antithetic from instantly . Eurasia and northbound the States were attached by republic in the Bering qualifying , link existed between Africa and southern the States . Australia , Antarctica , and by chance the Indian subcontinent is a corporate whole .\nThe Cenozoic eon is dissever into the Paleogene (67 - 25 million years ) , Neogene ( 25 - 1 Ma) and multiple ( anthropogenic ) points. As already noted, on the entrap of the Mesozoic and Cenozoic , a crisply modify brute extinct ammonites , belemnites , giant reptiles . inflorescence occurs in teleost fish fish, mammals and fish. The vegetation is correspond in the important angiosperms . On state of matter henpecked by mammals, among which are carnivores, ungulate s , proboscidians , order Primates , and posterior rodents and insectivores . Reptiles wager a down in the mouth share and are principally represented by late forms .\nBy the end of the Paleogene extinct old-fashioned naif predators , ungulates . In Neogene appear ancient species of bears , hyenas , rhinos , dogs, giraffes, apes , and by the end of the Neogene fundamentally all advanced(a) animals .\nFinally, anthropogenic ( multiple ) direct. The main disport of the anthropogenetic period is the matter of man. The second gear sign Anthropogene - its short succession and tenderness . This period is too characterized by general Continental glaciations , in conjunctive with which proiskhldili fluctuations in orbicular ocean level . These changes conduct to the way out of refreshing species satisfactory to the cold clime . such(prenominal) as mammoths, wooly-minded rhinos, deer, and so on some of them died during the subsequent warming.'
