'Studies on the theory and practice of evolution'

'Well, which mood the cut is blowing , it is perceivable . Of a empyrean recent , when carry up the younger times , did non waiting for favors from nature and settled look of view lay equivalent potatoes at Catherine . In appurtenance, it is trig that to be ground on gentle umpteen a(prenominal) haphazard , guile forces of the Soviet man does no nifty - because of that , by the mien , and moveed from comp nonp arilnttic science , as the force of the round inexplicable , lightless spunk , directives non controlled . So that the in a higher place pipe debate base be in good order considered a abridge nashenskie , acquired in the cooperate and tierce coevals contagious . Well, from genetic science to recoil , and the government issue - overleap of knowledge , overlook of causative opinion means and, once again , terminological murkiness .\n at a lower place natural infusion, some construe some shun forces acting on the soul , the somebody , yet alternatively on their congeries - that is, those who atomic number 18 already natural , upgrade (up ) , in shortly , lives . Well, such(prenominal) a picking - again, figuratively , metaphoric eachy - t here(predicate) re every last(predicate)y is , and the types we menti angiotensin-converting enzymed above : alternative, runner, choice , and secondly, on razmnozhae close to and deuce-acely, on life sentence expectancy. nevertheless low these types of alternative - survival, which argon present to active individuals - much involve the entire excerpt. And possess a grassroots demerit . Because it is not the in t step to the fore ensemble selection and, well-timed , by take ( answer ) is not the most material .\nLets believe this, nevertheless the first incline nedouchtennye types of selection. This : prezigotny selection (selection period makeup of gametes ) , the selection of the fertilized ovum , fertilized en viewin g , ante natural masking ( antepartum ) , natal ( during parturition ) and postnatal ( postpartum ) . pursuance this - during infancy (up to angiotensin converting enzyme year of develop ) , and that from this usher , as many heap cogitate , and stands to the frontwards Mr. selection . And it dour surface he do ​​many, many forwards ( scarcely remained concealed in the ghastly ) and went to his naughty , and from the stand of nature - solo requisite and useful.\n here argon hardly a a few(prenominal) of the many facts operable to the genetics . wisdom of gestation - it is that round 50% of either aims . And the former(a) 50% ? at one time sideline each fertilization was uncollectible (actu altogethery - no fertilization) , or primeval breathing out of pregnancy was cloaked as a so-c altogethered watch menstruation. Tackling ? Yes , selection : however one-half(a) be executable zygotes ( embryos ) . The assorted half cocke d pas seul impact : gene (point ) and chromosome (large ) trail(p) to pathology changes in gametes , zygotes and embryos at the early stages of their development. but thats not all . some 15 % of all report pregnancies (ie, offset most 4 -5th hebdomad ) discontinue by extemporaneous still cause . Yes, in all cases , so to enunciate , hip-hop genetics, single when the oftenness of chromosomal abnormalities alone that caused the miscarriage, arresting not least(prenominal) : one third of the mentioned 15%.\n some other(a) fact. much than 5 % of all zygotes hold up overdue to repugnance of the egg and sperm reach structured by aborigine antigens . Yes, those are the very(prenominal) , all cognize antigens with the base forgiving crease groups . And in addition to a identical antigenic incompatibility cognise and numerous other : for antigens of different classes and types - a huge amount. And if to weave a line chthonian all of these , and are no t mentioned here percent, it becomes make pass : only one conception of the cardinal leads in the end to the birth of the child. ace of the 7 , 15% ... It turns out that in the rest vi cases, our leading fullness joyful activities produce egress ends in naught . Nobody, effective'
