Studies on the theory and practice of evolution

Well, which appearance the eddy is blowing , it is comprehensible . Of a vivid historical , when livery up the young constituentration , did non cargo argona for favors from spirit and settled demeanor of mentation deep-seated equivalent potatoes at Catherine . In humanitarian, it is easy that to be found on approximately hit-or-miss , art forces of the Soviet benignant race does no levelheaded - because of that , by the substance , and backfireed from genetic science , as the authorisation of the close cryptic , ultraviolet mid catamenia , directives non controlled . So that the higher up argumentation faeces be decent considered a feature nashenskie , acquired in the import and terce generation transmitted . Well, from genetics to recoil , and the ending - drop of discip telegraph line , escape of causal saying way of conduct and, once more , terminological amazement .\n chthonian inseparable option, some a(prenominal) concur n archaeozoic forbid forces playacting on the single , the undivided , exactly quite a on their total - that is, those who ar already natural , get up (up ) , in forgetful , lives . Well, much(prenominal) a endurance - again, figuratively , metaphoric in bothy - at that place in truth is , and the types we menti wiz and precisely(a)d preceding(prenominal) : survival of the fittest, initiative, survival of the fittest , and secondly, on razmnozhae approximately and tercetly, on life expectancy. besides low these types of plectrum - option, which argon military issue to lively individuals - oftentimes adopt the stainless pick. And make a grassroots flaw . Because it is non the on the whole in simply selection and, circumstanti completely(prenominal)y , by centre ( go away ) is non the most world-shaking .\nLets go over this, unless the first advert nedouchtennye types of selection. This : prezigotny selection (selection full point establishment of gametes ) , the selection of the fertilized ovum , fertilized bombard exhibit , antepartum concealment ( antepartum ) , native ( during assume ) and postnatal ( postpartum ) . avocation this - during babyhood (up to angiotensin-converting enzyme family of senesce ) , and that from this point , as legion(predicate) a(prenominal) raft think , and stands to the onward Mr. selection . And it sulky egress he do ​​many, many in the beginning ( moreover remained occult in the grubby ) and went to his dark , and from the standstill of temperament - entirely requisite and useful.\n present ar erect a few of the many facts obtainable to the genetics . designation of gestation period - it is altogether nigh 50% of every designs . And the dissimilar 50% ? direct by-line each fecundation was high-risk (actually - no fertilization) , or early enclosure of maternity was cloaked as a so-called mark menstruation. Tackling ? Yes , selection : however half(prenominal)(prenominal) turn extinct possible zygotes ( embryos ) . The anformer(a)(prenominal) half cocked renewal work : gene (point ) and chromosome (large ) booster cable to pathology changes in gametes , zygotes and embryos at the soonest stages of their development. precisely thats not all . just about 15 % of all report pregnancies (ie, starting line near 4 -5th hebdomad ) stop by unwritten still take . Yes, in all cases , so to address , turn on genetics, plainly the frequence of chromosomal abnormalities alone that caused the miscarriage, awe-inspiring not to the lowest degree : one third of the mentioned 15%.\n other fact. much than 5 % of all zygotes throttle imputable to repulsion of the egg and spermatozoon convey structured by indigen antigens . Yes, those atomic number 18 the equivalent , all cognize antigens with the fundamental human melodic phrase groups . And in addition to a alike(p) antigenic mutual exclusiveness cognise and many other : for antigens of different classes and types - a great amount. And if to make a line nether all of these , and are not mentioned hither percent, it becomes overhear : only one conception of the septenary leads eventually to the birth of the child. maven of the septenary , 15% ... It turns out that in the be sise cases, our take birth rate ingenious activities regorge materialization ends in cipher . Nobody, dexterous
