A new study shows that increased UV radiation can have an effect on human fertility over generations. On average, the lifespan of children born in years that had a great deal of solar activity was 5.2 years shorter than other children. Children who were born in years with lots of sunshine and who survived were also more likely to have fewer children, who in turn gave birth to fewer children than others. This finding shows that increased UV radiation during years of high solar activity had an effect across generations.
