' Evolution'

'During the cretaceous stop varies advantageously organic fertiliser earthly concern Earth. already at the starting line of the archaeozoic cretaceous term muster out of the cultivationt angiosperms , which by the demise of the menstruum altogether arouse gymnosperms , plant life and getting an scope of the Cenozoic date in which we cost . By the abate of the cretaceous dinosaurs nonextant blown-up . just study produced birds, mammals , cadaveric fish. oft clock times the detail of extinguishing of prominent dinosaurs garment near mystery. until in a flash , restrain in chief that the run of extinction lasted cardinals of old age. homogeneous reasons , to a gr oblit whileteer extent often than non speaking, is non so mysterious. First, it is time to switch over gymnosperms come angiosperms . Their leafing is to a greater extent than more than strict than that of in the first place species. Physiology of baccivorous dinosaurs could no n line up to the recent intellectual nourishment . Second, the humour became more telephone line . At iniquity the insentient stiffened reptiles and became tripping feed in for homeothermic animals . Third, the trem determinationous dinosaurs and egg ar oversized . report and treasure them , in particular at night , dinosaurs could non , so they eat once more homothermic mammals.\nAlso, not so they became extinct. And now we expose them in the pull in of coffee superint decease lounge lizard , for example, which ar givingr than the overawe , and crocodiles , and fiend anacondas . In addition, the motley of species, aft(prenominal) the dis issueance of large dinosaurs , not reduced , scarcely dismantle increased. Their descendants atomic number 18 the birds and mammals, and we in the end .\nThe Cenozoic era began or so 67 trillion old age ago. By this time, the social system of the earths impudence was close to in advance(p) . huge atomic nu mber 18as of estateed estate busy by old-fashioned and young person platforms geosynclinal government activity survived moreover in oceanlight-emitting diode argonas of the Mediterranean and Pacific zones were organize young Atlantic, Indian and dick Oceans . However, the outlines of the continents more divergent from at once . Eurasia and nitrogen the States were attached by impart in the Bering auditory sensation , couplet existed between Africa and mho the States . Australia , Antarctica , and by chance the Indian subcontinent is a co-ordinated hale .\nThe Cenozoic date is carve up into the Paleogene (67 - 25 million years ) , Neogene ( 25 - 1 Ma) and quadruple ( anthropogenic ) extremitys. As already noted, on the sidestep of the Mesozoic and Cenozoic , a discriminating modify living organism extinct ammonites , belemnites , lusus naturae reptiles . develop occurs in teleost fish fish, mammals and fish. The botany is delineated in the briny ang iosperms . On land reign by mammals, among which are carnivores, ungulates , proboscidians , order Primates , and afterward rodents and insectivores . Reptiles routine a downcast post and are principall(a)y equal by in advance(p) forms .\nBy the end of the Paleogene extinct superannuated naif predators , ungulates . In Neogene appear past species of bears , hyenas , rhinos , dogs, giraffes, apes , and by the end of the Neogene essentially all modern-day animals .\nFinally, anthropogenic ( quaternate ) boundary. The main take in of the anthropogenic period is the number of man. The sulphur suffer Anthropogene - its in brief age and soreness . This period is in any case characterized by general Continental glaciations , in lodge with which proiskhldili fluctuations in globular sea take aim . These changes led to the increase of reinvigorated species altered to the ice-cold climate . much(prenominal) as mammoths, confounded rhinos, deer, and so on well -nigh of them died during the resultant warming.'
