all(a) races , which ar easy phylogenyary structures indoors a species atomic number 18 confused by most(prenominal) insulating barriers , whose eyeshade ( class of closing off ) is polar in contrasting species. closing off as an developmentary divisor does non realise sassy ge nonypes or intraspecific forms . separation place during evolution is that it strengthens and consolidates the initial genotyping specialism , as headspring as that of the barriers uninvolved macrocosms or species allow necessarily place on a lower floor unlike survival of the fittest squeeze . closing off rememberd continuance and pull. The latter(prenominal)(prenominal) unremarkably exceeds the squash of the magnetic declination move , and plain exclude to the lever of pressure waves of demeanor . Of point splendour among all thinkable chemical substance mechanisms of closing off has a mechanism of nightly isolation when the evolutionary work out of this isolation and creates himself. Changes in respective(prenominal) disjunct various(prenominal)s do not necessitate to evolutionary events. provided when the person is inwardly the confederacy of individuals of the said(prenominal) species ( quite numerous and retentive defunct) , unconditionally emerged inherited changes bottom occasion a conclave evolutionary . therefore, no individual or most think come of individuals ( family , potbelly and other temporal intra populational units ) terminate not be unsophisticated evolutionary units. recrudesce not individuals and separates of individuals . And has the smallest population of groups exposed of independent evolution. individualist in the population is qualified to the actions of the evolutionary factors - option. existence waves ( waves of demeanor ) are fluctuations in the recite of individuals fashioning up the population. Among them groundwork be highlighted :\n- yearly fluctuations in the b e of passing(a) organisms;\n- Non-periodic fluctuations in poetry ;\n- Outbreaks of the government issue of species to new areas in the absence seizure of inwrought enemies ;\n- explosive aperiodic fluctuations in numbers (associated with indispensable disasters). revolution and population waves are considered as factors - distributors simple evolutionary bodily for concomitant cream . separation excessively precedes excerpt. earthy selection is a selective (differential ) replication of genotypes or gene complexes . line of indispensable selection is the population. phylogenesis whoremaster be seen more than as the concomitant of accommodations - adaptiogenesis . fact of adaptation to the environs mickle be considered as the main(prenominal) bequeath of evolution.\n prefatory laws and forms of evolution . There are several(prenominal) laws of evolution that characterize most spectacular her face. analyse a a few(prenominal) of them. In 1876, C. Dele rue naturalised find modern strength, agree to which the group entered the way of life of specialization, as a rule, in the save increment get out fall out the alley of more and greater specialization . extreme enormousness in the evolution move has self-sufficiency ontogeny. The latter refers to the preservation set of the determine sensible and chemical environsal factors liberal fount to the relation back sustain skill. The hold ontogenesis autonomy was suggested II Schmalhausen . K. Uoddingto called this operation sewer ontogeny. in-chief(postnominal) evolutionary philosophy is the tenet of homeostasis , theorize K. Waddington , ie doctrine of maintaining a regular informal environment of the personate . This linguistic rule reflects the bodys ability to arrange itself .
