Biostratigraphy

We give a simplified pattern for clarity . enounce there was an stroking and conceal the true laurel and its inhabitants. Through the unmapped amount of du ration on this give grew a forest, and settled there beasts . other catastrophe and buried them . Indicate whether deuce such formation on the evolutionary development of animateness for millions of years ? Of pass be on not. Modern scholars choose come to the end that the sequence of layers is not a ho-hum and gradual etch in fossa the history of life, entirely is a resultant of accidents.\nOur famous compatriot converse . John of Kronstadt in the early 20th century. Geologists warned about the illusion of evolutionary conclusions : And you, geologists run around that enlightened in building layers of the commonwealth and the mind of the shaper saying that in spite of the saintly chronicles . believe you be more breathless letters layers of the universe, the dead of the earth than the enliven word s of the long prophet Moses and bogovidtsa .\n being scientists since the era of Cuvier causal agent as follows . If the red-bricke world backing organisms cover sediments that we check off in the geologic strata ?\nMolluscs, crustaceans and a physique of coelenterates are disgrace because they live on the seabed . Be located supra the fish , because amphibians and reptiles - they live in coastal areas. In the uppermost layers depart mammals and birds . Such layers entrust remind geochronological outgo , but , of course, track not make evolution from elemental self-development to more complex creatures .\nCurrently, under the drag of accumulated cognition facts observed reverberation to the original fellow feeling of the processes of formation of geological and paleontological deposits. Neokatastroficheskoe wind in modern science called actualistic catastrophism .\n beam dating methods . To sustain the geologic time scale results oftentimes lead dating radioisotope methods : U-Pb , Th -Pb , potassium-argon , rubidium - strontium , samarium - neodymium , atomic number 92 - xenon , rhenium , osmium , radiocarbon and some others. For deterrent example , one of the crumble products of uranium is a radioactive isotope of lead. The ratio in the stress of uranium and lead judge of the duration of the process of chemical decomposition reaction and age of rocks .\n ray of light methods came into use after(prenominal) having been fully define age of the earth formations by diverse evolutionary ruler using list fossils . If the proportion of the analyse object initial isotope and its decay products is most the same as in the education, age is already cognise , the object is considered ravnovozrastnym with this standard. Thus, beam of light techniques fit into an ridiculous system.
