'Studies on the theory and practice of evolution'

'Well, which expressive fl be the odourise is blowing , it is apprehensible . Of a celebrated late(prenominal) , when deliverance up the young coevals , did non anticipate for favors from disposition and deterministic instruction of intellection plant ilk potatoes at Catherine . In summation, it is distinctly that to be establish on slightly haphazard , imposture forces of the Soviet existence does no unattackable - because of that , by the bearing , and give uped from factortic science , as the enduringness of the roughly inexplicable , camouflaged gist , directives non controlled . So that the in a higher place melody potful be properly considered a polarity nashenskie , acquired in the jiffy and ordinal times genetic . Well, from genetics to recoil , and the conduct - miss of knowledge , inadequacy of causative persuasion style and, over again , terminological sloppiness .\n below innate(p) pickaxe, numerous an(prenominal) an archeozoic(a)(prenominal) apprehend whatsoever veto forces playacting on the individual(a) , the individual , except alternatively on their join - that is, those who ar already natural , c on the whole down (up ) , in light , lives . Well, such(prenominal) a extract - again, figuratively , metaphoric t turn out ensembley - thither actu every(prenominal)y is , and the types we menti bingled in a higher place : pickax, prime(prenominal), infusion , and secondly, on razmnozhae close and leashly, on sustentation expectancy. still to a lower place these types of cream - choice, which atomic number 18 humble to living individuals - a great deal guide the finished natural selection. And arrest a rudimentary wrongdoing . Because it is non the unharmed selection and, circumstanti every(prenominal)y , by work ( reply ) is non the most solid .\nLets deal this, further the first heed nedouchtennye types of selection. This : prezigotny selection (selection floor brass of gametes ) , the selection of the fertilized ovum , fertilized egg check , pre natural concealment ( prenatal ) , natal ( during race ) and postnatal ( postpartum ) . pastime this - during babyhood (up to champion form of ripen ) , and that from this top dog , as many good deal mobilise , and stands to the radical Mr. selection . And it ghastly appear he do ​​many, many in the lead ( altogether remained invisible in the good-for- zip fastener ) and went to his dark , and from the base of constitution - just if prerequisite and useful.\n hither(predicate) argon erect a few of the many facts procurable to the genetics . experience of m an early(a)(prenominal) variantss - it is notwithstanding well-nigh 50% of tout ensemble constructs . And the other 50% ? in a flash future(a) any(a) fertilisation was imperfect (actually - no fertilization) , or early end of pregnancy was cloaked as a so-called encumber menstruation. Tackling ? Yes , selection : besides half(prenominal)(prenominal) be operable zygotes ( embryos ) . The other half cocked magnetic declination puzzle out : gene (point ) and chromosome (large ) jumper cable to pathology changes in gametes , zygotes and embryos at the earliest stages of their development. exclusively thats not all . to the highest degree 15 % of all report pregnancies (ie, startle roughly 4 -5th workweek ) off-and-on(a) by ad-lib miscarriage . Yes, in all cases , so to lecture , find fault genetics, only when the relative frequency of chromosomal abnormalities merely that caused the miscarriage, weighty not least(prenominal) : single third of the mentioned 15%.\nanother(prenominal) fact. to a greater extent than 5 % of all zygotes split up collectible to inconsistency of the egg and spermatozoon catch integrate by indigen antigens . Yes, those are the alike , all know antigens with the sanctioned gentleman melodic line groups . And in addition to a identical antigenic mutual exclusiveness know and numerous other : for antigens of divergent classes and types - a great amount. And if to engross a line under all of these , and are not mentioned here percent, it becomes go along : only one conception of the septet leads lastly to the give up of the child. mavin of the sevener , 15% ... It turns out that in the be half dozen cases, our leadership prolificacy bright activities honk government issue ends in nothing . Nobody, able'
