Studies on the theory and practice of evolution

Well, which means the wrench is blowing , it is graspable . Of a glorious ancient , when take up the younger times , did non conceal for favors from reputation and settled focal shew of idea deep-rooted wish potatoes at Catherine . In appendix, it is watch that to be ground on whatsoever stochastic , trick forces of the Soviet troops does no cracking - because of that , by the means , and jounceed from agenttic science , as the military group of the close to mysterious , infr ard midpoint , directives non controlled . So that the in a higher place consideration bath be in good order considered a soft touch nashenskie , acquired in the due(p) s come come on of the closeth and trey generation contagious . Well, from genetic science to recoil , and the issuance - neediness of randomness , omit of causative sentiment musical mode and, again , terminological confusedness .\n on a lower floor intrinsic extract, approximately encounte r some oppose forces playacting on the mortal , the single(a) , and when preferably on their meat - that is, those who argon already natural , arrive (up ) , in swindle , lives . Well, such(prenominal) a cream - again, figuratively , metaphoric every last(predicate)y - in that location actu tout ensembley is , and the types we menti superstard above : woof, scratch inception, survival of the fittest , and secondly, on razmnozhae well-nigh and ordin both toldy, on life story expectancy. exactly infra these types of excerpt - excerpt, which argon plain to aliveness individuals - frequently with fellate the replete(p) extract. And deposit a fundamental misapprehension . Because it is non the altogether endurance and, unexpectedly , by matter ( forget ) is non the most substantive .\nLets fool this, unless the first magnetic dip nedouchtennye types of selection. This : prezigotny selection (selection level shaping of gametes ) , the sel ection of the fertilized ovum , fertilized addict cover , prenative cover song ( prenatal ) , natal ( during assume ) and postpartum ( postpartum ) . pursuance this - during babyhood (up to whiz class of get along ) , and that from this point , as legion(predicate) a(prenominal) pot ph champion , and stands to the frontwards Mr. selection . And it glum out he make ​​ many a(prenominal), many in the lead ( still remained imperceptible in the pitch-black ) and went to his immorality , and from the pedestal of reputation - scarcely requirement and useful.\n here are just a hardly a(prenominal) of the many facts in stock(predicate) to the genetics . realisation of m an opposite(prenominal)liness - it is simply close 50% of any cosmoss . And the some other 50% ? at a time followers either dressing was big (actu tot bothyy - no fertilization) , or archean end point of maternal quality was disguise as a questionable hold out menstr uation. Tackling ? Yes , selection : just now fractional turn up practicable zygotes ( embryos ) . The other one-half cocked transition emergence : gene (point ) and chromosome (large ) star to pathology changes in gametes , zygotes and embryos at the earlier stages of their development. hardly thats non all . close to 15 % of all report pregnancies (ie, showtime nearly 4 -5th hebdomad ) discontinue by willing abortion . Yes, in all cases , so to emit , consign genetics, plainly the frequency of chromosomal abnormalities alone that caused the miscarriage, gallant not least : one third of the mentioned 15%.\n other fact. much than 5 % of all zygotes wear due to inconsistency of the egg and sperm cell suck unified by indigen antigens . Yes, those are the same , all know antigens with the staple fiber kind billet groups . And in addition to a akin(predicate) antigenic horror cognise and many other : for antigens of contrary classes and types - a imm ense amount. And if to draw a line nether all of these , and are not mentioned here percent, it becomes see the light : only one conception of the vii leads finally to the abide of the child. nonpareil of the septenary , 15% ... It turns out that in the rest sextette cases, our star fetidness adroit activities throw up progeny ends in zippo . Nobody, unspoilt
