For generations, a bedrock concept of biology was that genetic mutations are necessary to pass traits from one generation to the next, but new developments in genetics are challenging this fundamental assumption. A growing body of scientific evidence demonstrates that chemical alteration of the way a gene functions, whether through exposure to chemicals, foods or even traumatic experiences, may not only affect the exposed individual, but also the individual’s offspring for two generations or more. This interaction between genes and the environment, known as epigenetics, has revolutionized the understanding of how genes are expressed within an individual and how they …
