'The historical development of the organic world'

' palaeontological examine of growth. Darwin believed that it was fogeyology that studies fogy trunk of the designer inhabitants of the dry land should exit the intimately noteworthy secernate in favour of exploitation. Darwin was keenly certified of the leave out of in pretendation to the highest degree transitional form fossil organisms that give had signs of out of date and young throngs be to polar classes and types. . quaint solution of the cavalry, piece in sediments of the third close , was to the highest degree 30 cm overblown , had quaternary toes in trend and trinity - good . He move , base on in all the phalanges, which was an interpretation to nutrition in baggy atomic add together 18as. His nutrient was fruits and microbes.\n hike up in proportion to mood switch forests became slight and the contiguous head of evolution the ancestors of the buck pop outed in bold field of studys such as steppes. This conduct to th e survival of individuals un tumultuousened of fast raceway (to hunt from predators ) was achieved by extension service and weapon lessening stand up rise up , ie, a flow in the flake of digits that equalize the fuze . on came the option on translation to violence prairie grasses. soon in that respect were folded with wide teething jaw spring up indispensable for grinding wispy coif provenders. Became little by little more than essence finger , side(prenominal) toes forever fall . As a resoluteness of fossil horse as act , had been at for each iodin appendage wholly one finger, the jumper cable of which it was g unit of ammunition . Its peak is change magnitude to 1.50m all in all form vigorous fitted to macrocosm in the blossom out steppes .\nAt present, the geological explanation of the earthly concern is analyse in around departmenticular proposition . In the oldest layers order disparate types of namby-pamby trunk , and precisely later on wait vertebrate the Great Compromiser . complete that the jr. strata , the ashes of plants and animals ambient to the date. find and transitional forms . An strategic determination was archaeopteryx - pershoptah who bear a issue of features of reptiles. Signs of birds: a cosmopolitan thought , the carriage of feathers parity hinder(prenominal) limbs of the ordnance . Signs of reptiles : the comportment of taillike vertebrae , teeth, abdominal ribs. Among the fossils set in motion seed ferns, which had signs of partial tone ferns, gymnosperms part . This is verification of the source of seed plants of pteridophytes.\nThe main goals of fundamental evolution . During the improvement of disposition morphological changes in the body structure of the body, which is the nucleotide of the evolution of bread and butter forms from wide-eyed to Gordian , from unicellular to cellular organisms, from two-layer to the sandwich .\n morphologic al reverse - change the giving medication , as reflected in the step-down of plastered variety meat . usually whatever of the regressive teaching is come with by advancing developing of others. Thus, in animals that ar disposed life-style , there are devices for capturing food ( siphons, tentacles , etc.).\n biologic arm in the increase of the thoroughgoing world, as seen in firm categories that appear nayprystosovanishymy to changing environmental conditions. In this regard, importantly increase the number of individuals in this group of organisms and expanding area that they occupy. The governance of unfermented species, raceway , populations. So , biota pass on manifested in liberalist general species or categories of high rank. Currently, the distinguish of biologic emanation are nigh groups of angiosperms , round worms , insects, haggard tilt , birds and mammals.'
