[Correlation of ontogenetic and evolutionary processes in view of achievements of modern genetics: role of gene duplication].
I.I. Schmalhausen's concept about the interrelation of individual and historical development is analyzed from the positions of modern developmental biology and molecular genetics. The role of gene duplication in evolutionary, ontogenetic, and adaptable processes is discussed. The data on mechanisms of functional diversification of duplicated genes (exon-intron structural changes and point mutations) in these processes are submitted. The modern synthesis outlook in developmental biology is regarded.
