Like mutation, but rinses out in four generations! A new study finds that exposure to high levels of environmental toxins produces epigenetic changes in rats' sperm. "Epigenetics does not involve DNA sequence changes but chemical modification of the DNA." Ultimately, this may help to explain why certain human diseases, such as breast and prostate cancer, are becoming more common. The increase in the incidence of these diseases cannot be accounted for by a normal rate of genetic mutation, but epigenetic damage could be the culprit.
