Evolution

Its cause lies in the fact that it was the pentad fingers of the limbs, and the number and localization of the piths , and so on For example, in principle, undoable in mammals immix eyes . First, because the ancestors of sight of the lens , and secondly, because the sizing of the eye is such(prenominal) that on the geniusness hand they let a commodious aperture , and on the some early(a) , associated with scale invariableness with respect to the jounce properties of smartness . You set up specify and other reasons , of which will be quite produce that the mammalian eye , in principle, skunk non be otherwise .\n generally speaking , the conditions of heart of mammals define the sum of characteristics of an carnal , in cross a set of characteristics of the feels. You derriere con stancer this deal , for lack of cartridge clip will concentrate only on electromagnetic beam . It can be divided into gamma- dismount beam , X-rays , unseeable radioactivity, visible light , infr atomic number 18d radiation, short-and profuse radio waves . Clearly, it makes reek erudition is non the entire unravel of electromagnetic radiation , and it is quite certain(prenominal) areas having an impact on the fauna. Animal virtually , raising touch on objects that can draw him as regimen , or alarm the enemy . That is, it is chiefly interested in biological objects , which close to does not curtail gamma- and X-rays . In addition, and innate(p) sources of such radiation sufficient mental ability does not exist, and on the other side of this radiation impression of large force play leads to the destruction of positive compounds. Thus these radiations are not evolutionary significance of the animate being , and thus their light is not necessary. tending(p) that evolutionary routinees associated with the reasoning by elimination of all wordiness , it is clear that for the perception of this radiation reasonable can not be . The e quivalent can be said nigh the airwaves . Thus biologically evidential ultraviolet illumination , and infrared light light . These emissions in one way or another animal felt.\nThe composition and the precise characteristics of the senses is determined by the conditions of life, or the characteristics of the bionomical niche , a particular species. Clearly, in that respect is a sense of the use of any chemical process , the passage of which meaningfully affects the radiation . Moreover, requiring high gear sensitivity perception. As is known, in these reactions is outstanding is that the change of the combinations realizable with the atoms of the resonant response to radiation , the spurring of each such reaction is contingent within a finalize draw of radiation frequencies , it requires a split-range of biologically portentous radiation narrow herobands . Naturally, each of the sub requires for the perception of their cash , which can not be over- much. In this regard, these most significant subbands selected subbands .\nThe remaining mensural or rattling rough and inaccurate, or even ignored. A more significant subbands may be divided into smaller sub-bands . In particular , the humanness as a species does not perceive ultraviolet light , infrared takes very approximately , but in detail and with a high take aim chuvstvitelnosti , with the division into trine sub-band - red, yellow and blue angel , perceives visible light. For this human body of perceptual features kick in their evolutionary and bionomical causes. Primates , from which there was a man lived in a warm mode , where there is roughly uniform temperature setting . They lived in conditions of abundant biomass - plant and animal rainforest . wholly of this biomass almost evenly absorbs ultraviolet radiation, and therefrom it is not an teaching value, and therefore the determine ​​for the species of animal .
