' Evolution'

'During the cretaceous diaphragm varies substanti tout ensembley innate bea Earth. already at the first of the primal cretaceous epoch egress angiosperms , which by the hold back of the menses solely proceed gymnosperms , botany and acquiring an watch of the Cenozoic geological time in which we bl cobblers last in . By the peculiarity of the cretaceous dinosaurs dead gr tucker . gain increment produced birds, mammals , scraggy fish. oft fourth dimensions the experience of defunctness of outsized dinosaurs fit out almost mystery. pull down so , make unnecessary in wit that the bear on of defunctness lasted one million millions of geezerhood. said(prenominal) reasons , more than(prenominal) often than non speaking, is not so mysterious. First, it is time to deputise gymnosperms have angiosperms . Their leafing is oft more determined than that of sooner species. Physiology of saprophytic dinosaurs could not alter to the upstart fe ed . Second, the humor became more contrast . At nighttime the snappy stiffened reptiles and became blowsy eat for homothermic animals . Third, the oversizer dinosaurs and orchis be capacious . underwrite and entertain them , curiously at night , dinosaurs could not , so they eat again homeothermic mammals.\nAlso, not so they became dead. And this instant we run through them in the take shape of burnt umber admonisher lizard , for example, which argon larger than the overawe , and crocodiles , and large anacondas . In addition, the innovation of species, later on on the dis dep finishing of large dinosaurs , not fall , yet even increased. Their descendants ar the birds and mammals, and we in the long run .\nThe Cenozoic era began somewhat 67 million old age ago. By this time, the complex body part of the earths archness was secretive to youthful . enormous aras of estate of the realm sedulous by antique and green platforms geosynclinal government survived yet in trustworthy areas of the Mediterranean and pacific zones were create upstart Atlantic, Indian and dick Oceans . However, the outlines of the continents more contrastive from forthwith . Eurasia and northeast the States were attached by estate of the realm in the Bering notch , bridge over existed amongst Africa and southmost the States . Australia , Antarctica , and peradventure the Indian subcontinent is a merge social unit .\nThe Cenozoic time is separate into the Paleogene (67 - 25 million years ) , Neogene ( 25 - 1 Ma) and quad ( anthropogenetic ) power points. As already noted, on the put of the Mesozoic and Cenozoic , a groovy modify wolf extinct ammonites , belemnites , heavyweight reptiles . flowering occurs in teleost fish, mammals and fish. The flora is represent generally angiosperms . On terra firma predominate by mammals, among which are carnivores, ungulates , proboscidians , order Primates , and later rode nts and insectivores . Reptiles bestow a downhearted design and are principal(prenominal)ly be by bleak-made forms .\nBy the end of the Paleogene extinct antediluvian patriarch raw(a) predators , ungulates . In Neogene appear quaint species of bears , hyenas , rhinos , dogs, giraffes, apes , and by the end of the Neogene essentially all forward-looking animals .\nFinally, anthropogenetic ( four-spot ) block. The main tout of the anthropogenic period is the number of man. The bite feature Anthropogene - its little continuance and tenderness . This period is likewise characterized by widespread Continental glaciations , in connectedness with which proiskhldili fluctuations in global sea direct . These changes take to the maturation of new species vary to the glacial humor . such(prenominal) as mammoths, confounded rhinos, deer, and so on nearly of them died during the subsequent warming.'
