Last night Eddie Izzard travelled the world in search of his mother's heritage and tonight he's on a mission to find out more about his dad's DNA.He's back in Africa again, but this time he's smack bang in the middle of the continent, starting off in Cameroon. There he discovers some DNA cousins among the Bakola pygmies, before trekking off through the Middle East, and travelling across Europe. Finally, the comedian returns home to jolly old England to put the final pieces of the genetic puzzle together, once and for all.
