    Researchers have found that side effects from exposure to chemical toxins were passed down through several generations of lab rats. The results of the study are controversial, because of the unknown effects of being exposed to toxic chemicals on future generations of humans.

    Researchers have found that side effects from exposure to chemical toxins were passed down through several generations of lab rats.

    They found the chemical toxins changed the pattern of methyl molecules that attach to DNA and affected the fetus. The methyl groups would remain with and alter several successive generations resulting in the same health issues.

    The results of the study are controversial, because of the unknown side effects of being exposed to toxic chemicals on future generations of humans and the commonly accepted scientific belief that DNA only controls our genetic and physical traits.

    Michael Skinner, the lead researcher behind the study is quoted as saying: “There are two forces working against me. On one side, you have moneyed interests refusing to accept data that might force stronger regulations of their most profitable chemicals. On the other side, you have genetic determinists clinging to an old paradigm.”

    After the initial test using an agricultural fungicide called vinclozolin, Skinner and his team also tested the effects of DDT, BPA, and other chemicals on the lab rats.

    Skinner’s research has led to an entirely new field of study called transgenerational epigenetics, which looks at any inherited traits not covered by traditional genetic explanations.

    What do you think? Could exposure to toxic chemicals have a genetic effect that is passed down to offspring?
