From the producers who brought us African American Lives and Oprah's Roots comes a new PBS series called Faces of America. Popular icons like Stephen Colbert, Malcolm Gladwell, and Yo Yo Ma have agreed to have their DNA deconstructed to discover what role their genes play in their personal identity.

Among those being dissected (figuratively) is Mario Batali. Sure, there's probably some biological basis for him wanting to become a chef. But could his affinity for those signature Crocs really be written into his DNA? We'll find out when the four-part series airs in 2010.
