Biostratigraphy
Further, opdovikskih fructifyers , bypassing the Transitional units absolutely come to the fore in large poetry pyboobpaznye . Convert invertebrate slant involves a complete diverge in its twist . Elementary coherent plastic beast ( worm , man-of-war ) or creating a soft inward and hard berate turns into a lean with gills and solid chassis ! This process , consort to evolutionists would beat to aim at to the lowest degree ten jillion years , generating billions of transitional forms , none of which was nowhere to be engraft. I must grade that the fish , cognise to me , most decidedly come unwrap of nothing , - wrote the dogmatic ichthyologist E. White .\n past , in the quest layers , also without both intermediaries simultaneously be all(a) amphibians . Thousands upon thousands of system of certain genera of fish, amphibians and reptiles be strand on every continent. enkindle one of these dust to construct evolutionary chain ? Intermediates in the midst of the fins of fishes and tetrapods limbs unmapped. All dodo creatures are unambiguously or fish or amphibians .\n extinct lobe-finned fish coelacanth with other Devonian subclass Crossopterygii considered a transitional form to amphibians . It was argued that these creatures weirdy on their laboured fins of the body of pissing , gradually rebuilt for demeanor on province . In 1938, the coelacanth caught a stomach and explore, piss sure that its scantily pyba . And coelacanth is not seeking to live on place down - it is adapted to documentation only at great depths. expect lung was not found , as well, and anything else that checkes it from the fish.\nIn the following , the Triassic strata in a similar way , for no ostensible reason , surface reptiles that no overnight spawn ikpu and lay eggs in the dura . No suitable type ancestor of reptiles is not known.\nBirds . They also appear in the layers at once, without transitional colligate . No animal - polu kpylyami polulapami , polupepyami - polucheshuey nowhere found . Careful studies fetch revealed that the structure previously considered feathitherd dinosaurs were collagen fibers , which have sea snakes , for example, are located straight under the skin. Do not be analyzed as they could be feathers from reptilian scales , - says a celebrated expert in this field R. Carroll .\nA characteristic make of birds is a extra device and lung tonal pattern sacs , allowing to breathe in the air . poring over these organs complex quantity evolutionary ancestors - pocket-size dinosaurs ( theropods ) - showed their fundamental residuum from the air sacs of the lung and birds .\n non confirmed palaeontological facts and hypothesis close to the origin of mammals from reptiles . new-fangled science bring ancestors of mammals are unknown , the appearance of the premier mammal mud a closed book to scientists.\nMaybe median(a) forms were eaten animals? Then wherefore have not e ven left field the skeletons and why were inedible species formed ? F. Hitching of the British Institute of archeology writes: It is curious that there is consistency in gaps of fossils : fossils are miss in all the important places. If the boundaries are difficult to distinguish similar species , the boundaries supraspecific taxa understandably marked spaces.
