DESCRIPTION

Many humans have developed a tolerance to lactose, and thus an ability to drink cow’s milk. Did you know that this was the result of a genetic mutation, and that those with the mutation are likely the descendants of cattle herders? Steve and Ben take a look at genetic mutations in humans over time and how they have changed us. The guys also discuss: McGowan's Indi campaign inspires film, Brain Stethoscope Turns Seizures Into Music and US law lets teens delete web posts.
