What's the Difference?

We make split second decisions about others – someone is male or female, black or white, us or them. But sometimes the degrees of separation are incredibly few. A mere handful of genes determine skin color, for example.

Find out why race is almost non-existent from a biological perspective, and how the snippet of DNA that is the Y chromosome came to separate male from female.

Plus, why we’re wired to categorize. And, a groundbreaking court case proposes to erase the dividing line between species: lawyers argue to grant personhood status to our chimpanzee cousins.
