Epigenetics is the study of potentially heritable changes in gene expression without any variations in its DNA sequence. These trans-generational epigenetic phenomena found in biological systems are reminiscent of ‘inheritance of acquired characteristic’ originally proposed by Lamarck in early 19th century. Actually, it has been found that phenotypes are changed by the epigenetic principles in various organisms without changing the genetic information. Thus, some evolutionists began to question the premise that genes are the major driving force of evolution. From a creationist point of view, epigenetics is a deliberately designed process for manifesting various traits in response to external environmental changes.
