  Article:   REVIEW=== ECOLOGICAL AND GENETICAL IMPLICATIONS OF CLINE EVOLUTION.

Authors:  MANUELA DORDEA, NICOLAE COMAN. 		 
       
         
  Abstract:  As the environment changes permanently, and migrations occur recurrently, natural selection acts powerfully on population gene pools. More often, the gene flow hinders the action of natural selection. However, natural selection and migration are more often in a steady-state, that assure the specificity of local population gene pools, the clines being a result of such equilibrium, thus proving finally the evolution.
