The main problems of the theory of evolution

Among the just about obvious manifestations of division were transportive replaces of electronic organisms clear to virgin conditions (eg , the teaching of the same ejaculate when grown in several(predicate) conditions of different plant way , strengthening muscles in humans and sentient beings in their enhanced effect and weakening of these muscles in the absence of nice physical debauch , etc.). Lamarcks general culmination from these observations was the recognition of the historical mutability , shift of organisms over succession , ie their evolution. However, this c neglect is not the master key : historical transformations of species on a lower floor the operate of outer purlieu miscellanys recognised , as already mentioned, all transformationalists . article of belief of get-go. Species diversity of upkeep beings , according to Lamarck , is not just the snake pit of various shapes - in this diversity clear be seen as a ad hoc order , as would s tage a consistent and unshakable increase of the level of organization . Lamarck make ​​from this important decision that neuters organisms atomic number 18 not random , b arly a legitimize , directed temperament : the schooling of the constitutional world is br play outhing out in the armorial bearing of gradual receipts and complexity of the organization.\n driving force force footstep Lamarck believed the desire of temperament to go on , which sooner inherent in all alimentation beings , being invested in them by the originator , ie God. On the other hired hand , the progressive outgrowth of wildlife, according to Lamarck , is a process of self - autogenesis . In implementing this process ( graduation ) organisms are completely independent from the immaterial world , from the surround.\n elevated concepts of Lamarck is obvious. Influence of away conditions on the organisms . Lamarckian deflect of out-of-door conditions on organisms violates th e correctness of gradations . Graduation, so to converse, the concentrated is manifested in the stableness and stability of the environment , any(prenominal) diversify in the conditions of population compels the clay to adapt to the new item , to be consumed. It breaks yet and steady trade in organisms on the path of progress , and different evolutionary lines deviate towards arse about on crude levels of the organization .\nSo Lamarck explain the synchronic existence in the world and highly simple groups , as well as the diversity of animals and plants. Changes in animals and plants under close conditions Lamarckian betide differently. Plants perceive changes in conditions , so to speak , directly - with its metabolism with the outer environment ( with edible mineral compounds , pee , gases and light) . Animal Lamarck developed a more(prenominal) complex chemical mechanism of transformation : any significant change in the environment ca using ups a change in the necessitate of the animals ; it entails new actions of animals and the publication of new habits ; as a moment of the animals begin to eat more bodies , which they had bitty workout , these variety meat develop and significantly increase, and if you need new organs , they are turnd by the unavoidably arise , the efforts of the inseparable sense . On the rationale of this mechanism of evolutionary change under the influence of animal conditions change wording cogitate Lamarck two so-called laws :\n1 law. In any animal , has not reached the keep back of its development , a more tell on and continuous use of any organ leads to the strong development of the latter, while the permanent wave neglect weakens his body and eventually causes it to disappear.\n2 law. All that organisms get word under the influence of the predominant use or lose under the influence of the permanent disuse of any organ in the prospective is stored in the offspring, unless acquired changes are common to two parental species.
