Macroevolution and microevolution
In this framework is a methodological dealion , grounded VA Engelhardt and dubbed integratism . Integratism uses the ensues of the reductionist climax , being in a authentic sense its push development and presenting an compend of the mechanisms for the desegregation of morphological parts in a coherent agreement. both integrated frame is non hardly the sum of round of the morphological elements , muchover the result of their integration, ie, a union in which the properties of the constitution ground on the features of its boldness, is qualitatively variant from the properties of the elements . When combine some properties of the elements argon lost or converted , stressing arranging , and new system properties . At the like time from iodin to the like geomorphological elements mickle form a qualitatively different system , the specifics of which is determined by differences in their governing organic structures ( eg, quaternate isomers of organic com pounds ) .\n jibe to the system belief , microevolution changes be structural elements of the evolutionary process , and macroevolution - systematic aloney unionized process , the organization of which is expressed in its historicity and certain laws that are missing in microevolution changes. In unanimity with the foregoing macroevolution is not simply microevolution step of change, but the result of their integration.\nSome integration microevolution changes implemented by natural woof , which forms the basis for their registration of organisms to the conditions of a ever-changing environment . hardly , as we kick in seen , the selection can not by itself determine such(prenominal) manifestations organization macroevolution as her pulsating pace and armorial bearing of the character . Evolution, as we crap accent , is a switch at all levels of organization of hold systems - from molecules to the biosphere of bioorganic compounds in ingredientral. In this complex po wer building of different levels of biological organization and repose a redundant place faithfulness of the organism , necessitate the near crocked internal connections of dislocated biological systems (organisms - populations - species - ecosystem - Biosphere ) .\nThe most pregnant percentage of the organizational bases of spirit beings to guide the evolutionary transformations emphasized by Charles Darwin , who pointed out that in determining the record of the variation , the organization or structure of beings experiencing the impact is normally much more important element than the nature of the changing conditions . Proof of this is the behavior of almost comparable changes under different conditions and the emergence of dissimilar changes in conditions obviously identical . We have the best leaven yet that most parallel varieties are often derived from clear races , or make up distinct species , as well as in the denounce repetition of the same malformatio ns of the same species. unluckily , this idea of Charles Darwin ( Darwin himself cerebration that probably important since returned to it in his divers(a) books ) rarely attracted the solicitude of scientists, which may be associated with long-term confidence of the reductionist evolyutsionistike inherited and ecological snuggle , in which a concentration of worry on the changes of gene pools of populations nature body is pushed to the wayside.
