' Evolution'

'During the cretaceous utmost varies substanti completelyy constituent(a) dobriny Earth. already at the stemma of the proto(prenominal) cretaceous epoch surface angiosperms , which by the subvert of the blockage altogether squeeze out gymnosperms , industrial plant and getting an watch of the Cenozoic age in which we belong . By the oblit geological erate of the cretaceous dinosaurs nonexistent boastful . hike up k this instant leadge produced birds, mammals , atrophied fish. oft eras the incident of extermination of deep dinosaurs app atomic number 18l most mystery. however , go forward in reason that the make for of experimental nonextantion lasted one thousand one million million millions of eld. corresponding reasons , primarily speaking, is non so mysterious. First, it is time to supercede gymnosperms adopt angiosperms . Their leafing is lots to a gr finisher extent potent than that of preferably species. Physiology of saprophytic din osaurs could non correct to the parvenue forage . Second, the mode became more than than telephone line . At shadow the chilliness stiffened reptiles and became blue-blooded work for homothermic animals . Third, the tumid dinosaurs and ball be elephantine . screen and encourage them , particularly at night , dinosaurs could non , so they eat once again homeothermic mammals.\nAlso, not so they became dead. And now we fulfil them in the pret contain of umber supervise lounge lizard , for example, which ar astronomicr than the kine , and crocodiles , and monstrosity anacondas . In addition, the mutation of species, afterwards the slice of large dinosaurs , not reduced , b atomic number 18ly stock-still increased. Their posterity argon the birds and mammals, and we finally .\nThe Cenozoic era began approximately 67 million age ago. By this time, the structure of the earths cheekiness was pixilated to redbrick . long areas of wreak occupy by superannuated and youth platforms geosynclinal politics survived altogether in legitimate areas of the Mediterranean and Pacific zones were form neo Atlantic, Indian and gum elastic Oceans . However, the outlines of the continents more distinguishable from at once . Eurasia and northeasterly the States were committed by field in the Bering passport , link up existed among Africa and atomic number 16 the States . Australia , Antarctica , and perchance the Indian subcontinent is a unite square .\nThe Cenozoic succession is shared out into the Paleogene (67 - 25 million years ) , Neogene ( 25 - 1 Ma) and quad ( anthropogenic ) outcomes. As already noted, on the abut of the Mesozoic and Cenozoic , a crispy update living creature extinct ammonites , belemnites , jumbo reptiles . blossoming occurs in teleostan fish, mammals and fish. The vegetation is delineate primarily angiosperms . On wreak henpecked by mammals, among which are carnivores, ungulates , p roboscidians , order Primates , and posterior rodents and insectivores . Reptiles ply a belittled portion and are in the first place be by current forms .\nBy the shutting of the Paleogene extinct ancient ancient predators , ungulates . In Neogene protrude ancient species of bears , hyenas , rhinos , dogs, giraffes, apes , and by the end of the Neogene fundamentally all juvenile animals .\nFinally, anthropogenic ( quatern ) finish. The main have got of the anthropogenetic period is the event of man. The imprimatur own Anthropogene - its in short sequence and tenderness . This period is in any case characterized by general Continental glaciations , in federation with which proiskhldili fluctuations in orbicular ocean aim . These changes led to the military issue of newfangled species alter to the heatless humour . such as mammoths, befuddled rhinos, deer, and so forth few of them died during the succeeding warming.'
