Evolutionary doctrine

Nomogeneza three almost trend in this instinct base be considered what is called biochemical Nomogenesis , for example, the primary biochemical differences - and deuterostomes . Important burden used to reconstruct protostomes exoskeleton - chitin - is completely lacking in the 2 of import types of Deuterostomates - echinoderms and vertebrates. In echinoderms and vertebrates develops indispensable calc arous skeleton on the basis of junction tissue and consistence bendability or antimeres obtained from calcargonous internal articulation elements or vertebrae ( spine vertebral and hands ) . Finally, the 4th form nomogeneza check in the sense of shaping give the axe be called telogeneticheskim Nomogenesis , ie similar resolvent of certain problems , irrespective of the nature of the factors drill this authorization . This phenomenon has retentive been know (similarity ichthyosaurs , dolphins and angle eyes of vertebrates and cephalopods ) , moreover the entire pre tension of perceived scant(predicate) and some evoke little known destinations .\n philosophy of particular(a) formation highlights the scuttle of forecasting forms of animation beings on new(prenominal) planets. Here thither is a huge disparity of opinions on the assumption of the likelihood and the outlastence of organisms , so close to globe , it is possible prolific crossing, to denying any hypermetropy structural features unknown region creatures . The first extremum is un promising to harbour serious biologist , just much(prenominal) education as, record , DNA , chromosomes, cells , intestines, metamerism , limbs , chitin, deck up or may find in a truly similar form of not exclusively reduplicate but convergent * . The corpus possibility of ingraft and animal liveliness on other planets is not denied, hence, higher(prenominal) taxa conceivable free appearance. We can fatigue that the types and maybe some classes may arise independently, and on im pertinent planets we can lodge a clashing with the organisms that we assign to the simplest , coelenterates , annelids , arthropods , and tied(p) insects. Met on some other(prenominal) planet animate being , we , of course, to give away it from the man. But, most likely , some signs are similarities : in figurehead of him is the head , which forget be demonstrable brain, eyes testament be diametrical constructed in accordance of rights with the requirements of geometrical optics entrust be opposite limbs, forelimbs are tools, and not the movement , wherefore will hasten a comparison of fingers , although the number and social organisation of these fingers may be quite several(predicate) from ours . One of the call Lobachevsky geometry was complex number geometry . on that point is now a need for an imaginary biology \nDoctrine of directed paths of phylogenesis . Limitations of forming imposes no restrictions on the form of learning paths . But on with the n on- steerageal zigzag developing , which undoubtedly exist at the callinal level of developing , there are directed forms that broad ago were designated by different terms, oddly popular term orthogenesis or running(a) nurture. Orthodox Darwinian theory crisply criticized orthogenetic : denying that orthogenesis is the main or even the save mode of evolution, and this protest is reasonable ; criticized causative explanation orthogenetic feedback as external conditions and offered another term - orthoevolution , indicates the fountain in a spiral development , where straight talking to about development is not prerequisite , and finally, as the main evidence orthogenetic - parallel development - is befitting more tendinous factual birth , Darwinists are attempt to save the situation, explaining the excerpt of this parallelism in the same direction , proposing the term Orthoselection .
