Epigenetics, the study of changes in gene function that do not involve alterations to the DNA sequence, plays a pivotal role in understanding the complex interplay between genetics and the environment ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in ...

Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated. The ...
