Within the last century, researchers' understanding of genetics has undergone a profound transformation. Genes, regions of DNA that are largely responsible for our physical characteristics, were considered unchanging under the original model of genetics pioneered by biologist Gregor Mendel in 1865. That is, genes were thought to be largely unaffected by a person's environment. The emergence of the field of epigenetics in 1942 shattered this notion. Epigenetics refers to shifts in gene expression that occur without changes to the DNA sequence. Some epigenetic changes are an aspect of cell function, such as those associated with aging. However, environmental factors also...
