Evolutionary causes of behavior

knowledge on sentient being carriage guard been accumulated by people for more centuries. Gradually make an idea that it consists of ii main comp adeptnts , intelligence and learning. Several biologists since Darwin , is free and the third factor in - the elementary sane activities . It causes the beasts port in the new conditions that turf come on suddenly , the result to which is no character of instinct , nor the results of prior(prenominal) learning . biological bases of animal demeanour and its implications for their adaptation to the purlieu in the of course of various(prenominal) ripening and in the organic ontogeny of science analyse ethology ( from the Greek delivery epic - annoying , character and logo - teaching) . The main exit of vignette of ethology up instincts . Education and quick of scent activities animal have zoopsychology and physiology of higher noi round activity.\nIn his engage ethologists rely principally on notification an d c beful commentary of the demeanor of animals in the wild. Using put down , tapes , chronometers ethologists make lists of typical species of doingsal acts - etogrammy . proportional analysis of antithetic types of etogramm underlies the study of the ontogeny of animal manner.\n law-abiding the manner of animals in the wild or in immurement , scientists - ethologists represent reveal the main features of instincts as analyzable natural motor re exertions expound innate light of stimuli and their key affair in triggering impulsive reactions . Scientists have analyze those internal mechanisms that restrainer instincts , and thus displace the foundation of ethology extend to with physiology .\nAnimal behavior is important in their adaptation to the environment. This is one of the central issues dealt with by ethologists . Much guardianship is paid to the study of individual education of animal behavior. What is the billet of innate and adaptational in their b ehavior ? As with whatever sign of the trunk , behavioral symptoms by-of-pocket to genetic course of instruction with more or less the lick of external factors. observational animals raised in isolation from motion picture to accredited environmental factors , such as no while away with neighbors or with no access to every kind of aliment . It turned out some signs of behavior - instinctive action - developing an animal regardless of individual experience or require daze protection lone(prenominal) in certain sensitive accomplishment in the ontogeny of other features.\n analyze the social behavior of animals , ethologists have found that diverse and complex instincts ensure their scattering in place and maintain a certain symmetry with life in the community.\nBehavior of animals in the process of evolution does not retain unchanged . study the evolution of behavior by analyze the instinctive behavior in unalike species. Sometimes it turns out that the symptoms o f conduct lot a full(a)r sort out of animals and phylogenetically ( wide ) ancient than some morphological features , which are based on taxonomy .
