THE mystery of how human DNA evolves during someone’s lifetime looks a step closer to being solved.
Researchers in Japan have found evidence that environmental agents that cause chemical changes to our DNA throughout life may increase the amount of shuffling and mutation that occurs within our DNA during the formation of egg and sperm cells. So exposure of our DNA to reactive chemicals may actually drive evolution by promoting genetic diversity in our children.
