title: [Evolutionary theories of asymmetrization of organisms, brain and body].
abstract: Growth of a dispersion of elements of unitary systems (US) inevitably transfrorms them into the binary connected differentiations (BCD). So, at a level of genes, from bisexuals have arisen females and males, and at a level of hormones (mentality, behavior), from symmetric--asymmetric: functions, organs, right-handers and left-handers. All BCD are isomorphic. They consist of subsystems preservation (conservative) and change (operative) (SP, SC). SP is more important, than SC, therefore the dispersion of their elements is less, than elements SC. This base difference. It transforms a monomodal population in bimodal, direct "ecology, (environment, E US), in consequetn (E SC SP), and synchronous evolution in asynchronous (at first SC, later SP). Then for evolution "pay" only SC. Means, asynchronous evolution is more economical, than synchronous. In it adaptive sense of any BCD. All theories of biology are theories of US. They treat subsystems not as phased but as forms, therefore may not explain BCD. The general idea of asynchronous evolution--control centre of any function arises in the left hemisphere and in the right hemisphere gets only after approbation. Hence, creates asymmetry different phases of the same function in the left and right hemisphere, but not different functions. It has allowed to reject a lot of erroneous representations and to create adaptive, internally consistent, evolutionary theories of three-demensional asymmetry of organisms, a brain, a cis-trans asymmetry of pair organs and dextrality-sinistrality, having unique explanatory and predictive potential.
