Some recent scientific research suggests that acquired traits may be passed down to the next generations. Scientists at the Columbia University Medical Center found that roundworms that developed resistance to a particular virus passed on that immunity to their offspring, and for several generations.
Other research has found that human mothers may pass on acquired traits as well. During World War II, the Dutch suffered a devastating famine. Women who gave birth during this period had babies who were more susceptible to metabolic disorders such as obesity. Those children's children were likely to suffer from these conditions as well, research showed.
