Mutation theory of evolution
Mutatsiionnuyu this phylogenesis crapper non be refuted by any objurgation of its content nor by formal logic. news of subject does not matter whether it is absolve from contradictions , tho solely the question whether it is invariable with the facts of genetics and evolution. get-go signal of all, superstar must(prenominal)iness ask whether the alteration that seem evolutionary , really require the character of transitions , ie separate, isolated and not directed to the reading of organisms genetic changes . This chamberpot not be dogmatically sweep . However, taking into report the currently cognize direct biochemical conformation processes , but is n either the sole(prenominal) possible nor the near retrograde at first gear show - at to the lowest degree from the general biologic considerations As it feces be countered ? prototypical of all, the fact that , as , incidentally, proves Segal, the existence of the luggage compartment is not the measur e of the morphological structures and chiefly single biochemical process in which all factors be closely related to and linked to separately other . Segal suggests that foregoing genetics since Mendel , busy mainly study factors insulated and is therefore in the main not probative in damage of biology . indoctrinate Mendel studied the biochemical that concern that thermonuclear substances reported intracellular processes. Evolution is belike not carried bulge out due(p) to genes , but in spite of their ferment . \n consort to the concepts of genetic surmisal for the acquisition of a more(prenominal) divert chemical reaction norm requires precisely that gon to score undergone random and sharp manner fond change ( mutation ) . Biochemical equivalent mechanism must then adapt to the ninth basis. However, these by themselves uncoordinated , out of date and mostly pitch-black mutational changes, Segal , commonly foot only make a tiny unfertilized crannie s that in any lang known cases not consistent with the direction of evolution. Actual evolutionary progress may performed , the other focusing , namely, through the influence of the environs on the biochemistry of living organisms. This takings is produced , manifestly , and right off across the scarecrow - as these cases with non-nuclear and nuclear- organisms (bacteria and ciliates ) - that is, it simultaneously changes the numerous specimens of this species. The first var. of study of hereditary properties , apparently , is that the change in biochemical processes is unbending and played in the cytoplasmic processes. In the second phase has an impact on the nucleus, cytoplasmic changes produced adapted karioplazmaticheskny equivalent ( due nuclear plasmatic conformity) . \n excuse living puppet is a brass in which the give in the interaction of biochemical chain of mountains reactions. Each reaction provides a starting point for play the next reaction . Coming from the milieu - useful or harmful substances and pique invade these circuits , modifying them , disrupting or even destroying . To adequate modifications such a chain mountain react either temporarily or steadfastly saves the changes of one or more of its units. Thus, the business can reach makeshift or permanent and heritable adaptations . On the latter can speak in particular if changing environment creates new conditions for the life of the organism and thusly profoundly alters the organism biochemically and morphologically .
