We humans sure are skilled at creating division where none should exist. That's one of the central themes of National Geographic Channel's "The Human Family Tree" (9 p.m. EDT Sunday), which uses scientific advances to show how we're all connected.

Self-proclaimed "Dancing Outlaw" Jesco White is joining a family that is as outrageous as his own -- the hillbilly clan on Adult Swim's "Squidbillies."

It's easy to understand filmmaker Barry Blaustein's enthusiasm for high-school musicals, which he brings to the uneven documentary "Guys 'N Divas: Battle of the High School Musicals" (8:30 p.m. EDT Thursday, Aug. 27, Showtime).

Discovery Channel lucked into a sellable concept with "Out of Egypt," a new series hosted by Kara Cooney, a youthful UCLA assistant professor of Egyptian art and architecture.

"Mad Men" anti-hero Don Draper puts it best this way: "There will be fat years, and there will be lean years, but it is going to rain."

He's talking about the raincoat business in the third-season opener of "Mad Men" (10 p.m. EDT Sunday, AMC). But he could very well be addressing the state of prime-time television itself.

What a relief to have this TV show for grown-ups back on the tube. In a summer inundated by competition series and scripted castoffs on broadcast networks, "Mad Men" is a cable salve that heals all wounds.

Who doesn't want to be a millionaire?

Well, probably someone who has billions. Other than that, we all do. And with that, ABC is marking the 10th anniversary of its one-time mega-hit "Who Wants to be a Millionaire" with 11 prime-time episodes (starting 8 p.m. EDT Sunday).

Even if you decry the reality-TV genre, there's no question that some of these shows are better than others. And no producer is better at casting and editing than Mark Burnett, the mastermind behind "Survivor" and "The Apprentice."

As AMC's "Mad Men" readies a new season, questions raised at the end of last season swirl: Will 1960s-era ad man Don Draper (Jon Hamm) be faithful to wife Betty (January Jones) now that she's pregnant?

A studio executive described ABC's astronaut drama "Defying Gravity" as "Grey's Anatomy" in space. And it's true: The space scenarios in "Gravity" often defy common sense and are just as ludicrous as the medical-workplace hijinks on "Grey's."
