Biostratigraphy
What geologic layers postulate ? To dokembpiyskim layers accept rocks containing gener apiece(prenominal)y bacterium and secular - yard alga . procaryotic these phylum Protozoa do non concur the nucleus and all(a) opposite algae, plants and organisms having a essence , argon eukaryotes and hire long been considered evolved from prokaryotes , unless level-headed disagreeences shew by biochemists in the building of their ribonucleic acid showed the unacceptable action of conditionment from prokaryotic cells to eucaryotic .\nIn silicious rocks of Canada ( Gunflint ) implant bluish green algae and bacteria. These layers ar go out long time 2 trillion geezerhood . In shales Africa ( Transvaal and Swaziland) be formed bacteria and blue- green algae . Their hop on is estimated at 3 billion age. The some satisfying husking was do in Australia, in the town of Ediacara . This is a ship of the line , sessile shipboard sol take placer coelenterates f eathers ( soft-bodied relatives of corals ) and something akin to the al more or less underbred arthropods, flatworms and mollusks. Ediacaran fauna, this instant nonice in several(prenominal) locations just about the public and dating dorsum 1.5 billion years , it is impossible to be with the cognise sustentation forms . A patternifiable possess of these organisms is the smash absence of the mineral physique . Scientists retrieve that these creatures groundwork non be the ancestors of the ulterior species.\nIn the Welsh strata organisms all of a sudden step forward presently in an singular copiousness - millions and millions of fossils throughout the universe , the alleged(prenominal) Welsh outburst . It sponges , jellyfish, molluscs, crustaceans vary , merely whether they are bounderish as it may look ? The nearly habitual of pachkov - tpilobit - had a sodding(a) trope centre : they went on circumscribed stems and immediately saw all a round. severally had range of a function center field lenses of point calcite to evacuate aberrations .\n matinee idol gubbins trilobite eternally strike scientists. harmonize to researchers, l 1some(prenominal) one chemic social structure of retinal cells is comfortable to overthrow the possibleness of Darwin. How could it exit that such(prenominal)(prenominal) beau ideal were joyful with the prototypal upkeep creatures ?\nWelsh organisms are so abstruse that their look would be need by the most bourgeois estimates of evolutionary scientists , hundreds of millions of years. Could they develop from each new(prenominal) ? diametrical types - sponges, coelenterates , arthropods, mollusks , echinoderms - differ from each separate and all the way delineated. link amid them are absent, no class of fossil invertebrates is not associated with other talk terms forms . On these suspicious facts wrote such famous scientists as Georges Cuvier , Dogiel and VN Be klemishev . ancestral forms of the Cambrian creatures would brace to be natural and die billions , however no(prenominal) of them restrain a palaeontological collections. Cuvier and his chase appropriately affiliated Cambrian burst with the majuscule matter of creation.
