    When it comes to spurring Oklahoma to grapple with a century-old race massacre that schoolbooks had left behind, much of the credit is due to an unlikely historical resource: HBO.

  • Why Does My Lebanese Dad Have African DNA, When I Don’t?

    Dear Professor Gates: I have done an autosomal DNA test for most of my relatives and ancestors, including my father.

Both my brothers inherited 2 percent African DNA. However,…
