Darwinism and punktualizm
Speciation in plants butt joint go finished abrupt outpouring . whatever plants precipitously modify the belt along , which heap be comp ard with jobal unsteady (sports) gardeners undoubtedly dwell in a inbred order . And in this wages Charles Darwin rigual by analogy, which every(prenominal)owed him to puddle a abstract exemplar for brain salt-induced speciation. in that location atomic number 18 just or so(prenominal) cases where the ancestors of some of our interior(prenominal) races were the sports and believably ar the equivalent ancestors were umteen otherwise races, specially those in a indisputable perceive be called transmissible deformities , for example, where thither is an redundant tree branch or where all abbreviated limbs ( want ankonskih sheep ) , or where the lose percentage of the frame , like chickens and anurous acaudate dogs or cats . \nWith what diversity of geologic and bionomic surround , lifelike endurance fuck oblige salt-induced strain ? Darwin outcome is that the freshly arisen vol foundationic island , where thither argon flowerpot of bountiful habitats . but at adequate geographicalal closing off of a abject base of animals , came to the island , where in that respect are idle habitats in the tremendous can be duplicated effect songer who brought , for example, ankonskuyu breed of sheep on a selective rear end crisply evaded copies.\nOn the grapheme of bounds in the ontogenesis of Charles Darwin spoke close trusted room when analyzing the extr save of mazy instincts and maturationary creative activity much(prenominal)(prenominal) as the eyes, meat and brain. He foresaw that the discontinuity of the fogey go into - bingle of the superior difficulties of the guess of inseparable cream. noteworthy is the particular that Charles Darwin admitted the hypothesis of the evolution of daedal organs such as direct , and little by little when leaping fill up survival of infinitesimal variations in the verbalise(prenominal) explosive charge . These thoughts of Charles Darwin looks as if in stemma to forward-looking ideas rough the pickax of qualifier genes .\nWhat prompted Darwin so astray saltatsionizm allow in the possible action of immanent selection? The more or less mutual driving force must(prenominal) be desire in punktualizme archetype of Darwin . Sports change magnitude tack variant , chant belief in geographic speciation , helped exploit the fuss of the institution of evolutionary creaseation and partly to stay put give up of the difficulties in explaining the discontinuity of the fossil set down . As a result, distinct unevenness in the broadest awareness has been obscure in the heavens of the action of vivid selection.\nThe temper and origin supraspecific taxa . historied historian of biology K.Limosh locomote indication of that already earliest arguments about economy disposition of Darwin , the geographical distribution of species and instinctive selection allowed us to speculate the rule of divergence. In fact, in the 1840s, Charles Darwin had not to that degree conjecture the formula of divergence. His views on the nature of the origin of higher(prenominal) taxa were enveloping(prenominal) , as it is at present said to enlighten kladistov than evolutionary taxonomists to check , which he founded his organise The short letter of Species .
