The era of epigenetics (original) (raw)

The exploration of epigenetics has evolved from early philosophical debates on development to a sophisticated understanding of how gene expression can be affected by environmental factors without altering the DNA sequence. This paper traces the historical trajectory of epigenetics, emphasizing its importance in understanding cellular differentiation and complex traits in organisms. It highlights recent findings showing the role of epigenetic modifications in mediating environmental influences, particularly in mammals and honeybees, suggesting significant implications for phenotypic variation and biological identity.
