متن کاملGenetics and ecological speciation.
Species originate frequently by natural selection. A general mechanism by which this occurs is ecological speciation, defined as the evolution of reproductive isolation between populations as a result of ecologically-based divergent natural selection. The alternative mechanism is mutation-order speciation in which populations fix different mutations as they adapt to similar selection pressures....
متن کاملPhysiological aspects of genetics.
A considerable amount of evidence indicates that desoxyribonucleie acid is capable of duplicating itself, a property also possessed by genes. (By a selfduplicating material, we mean one which plays some essential role in its own production.) Watson & Crick (1) have proposed a new structure for desoxyribonucleic acid which not only takes into account the existing analytical and x-ray diffraction...
