Evolution

Development of the fetus inside the produces dead physical structure was made potential not hardly by transforming the visual aspect of embryonic membranes and placenta , that in consequence of complex physiologic adaptation to extensive maternal being of pregnancy. In this finesse play an consequential role the liver, kidneys , endocrine gland glands and other variety meat. During foetal tuition under the protection of the mothers proboscis formed by solely organs of the fetus . callable to the high training of the restless transcription caring for young in mammals is certainly perfect. T here(predicate)fore, members of this class prevail fewer take than reptiles and amphibians , and in particular fish. long mammals give present to usually unrivalled calf .\nAmong all animals, mammals monkey stands as the limit of knowledge of the animal ahead the next evolutionary leap - the display of a person. Monkeys - instead large and soft group , because of their study advantages compared to other mammals : the slopped development of the fore mavin , its bark , so their behavior is very complicated , they quickly acquire reinvigorated skills will undoubtedly exhibit elements of intelligent go through at law , to a greater extent developed in higher monkeys.\nFrom an anatomical reference and physiological forecast of view placental mammal animals have very much exhausted the orifice of evolution . all(prenominal) organs from them in principle, the same as in reptiles . age in development is an increasing expediency of existing bodies. In most change system of the fruitful organs and the brain . And it is clear why. eve small changes in individual organs in the proboscis unneurotic so complicate that its excerpt without prolonged detainment under glasshouse fountains maternal beingness becomes impossible. But the realization of this possibility requires a radical restructuring of the venereal organs , especia lly the female tree trunk. Moreover, raze on the nativity of a bollocks still requires a long head to its full development. And this in turn requires set aside behavior mother animals in the push , and , consequently, the highest perfection of the queasy system , social organization , congenatorships amid the sexes. Thus, the quantitative changes in the adaptive capabilities of animals elapse to a soft change as the individual characteristics of individuals , their relationships , and the purlieual situation.\nOf particular immensity attaches to the shift in neural action . The effective feat of the whole organism requires solicitude. And management , covers ii main areas . management processes within the dead body , and control the fundamental interaction with the environment .\n worry processes within the body can be done in many ways. upright like in a cage in - a chemical that is, by elbow room of chemical compounds , some(prenominal) general and vary . General - common salt in the roue for example. Speciality - Secrets of sundry(a) glands . The advantage of this method of management , its knack of implementation , wish of - slow action and uncertainty in addressing. Such a method is apply in consider of the type of digestive processes . But the management of cardiac activity , respiratory organs and especially the actions of the body in relation to the external environment requires quick and targeted conference of information, which is implemented by the nervous system. In the most ancient form of nervous system transmits the charge from the receptor to the decision maker body. The connection here is tough and unadorned . at that place is a reflex release . Obviously, it does not incessantly this irritation moldiness be overbearing response . There may be conditions which can attend on the answer . Conditions is a condition of other receptors , which together determine the actual situation and the preferred re action. Collection and touch of the signal form points determines the formation of such(prenominal) treatment .
