“Almost Human with Jane Goodall” (8 p.m., Animal Planet): Jane Goodall and videographer Bill Wallauer have followed the chimps of Gombe National Park in Tanzania for almost 25 years, chronicling their habits and habitat. In this special, which includes previously unaired footage from the Jane Goodall Institute, the pair brings viewers a close-up of the famous “G Family” of chimps. In the program, the apes showcase sibling rivalries and maternal instincts, and even display a temper tantrum or two.

“Desperate Housewives” (9 p.m., ABC): Gaby (Eva Longoria) is torn between her ex-husband and her ex-lover, the hunky gardener.

“The Amazing Mrs. Pritchard” (9 p.m., PBS): She’s a caring, efficient supermarket manager. How does she rise to the position of her country’s prime minister? That’s the saga of “The Amazing Mrs. Pritchard,” a five-part “Masterpiece Theatre” miniseries about a frustrated British subject who runs for Parliament to make a point: The people in power are a lousy lot. A political neophyte, Ros Pritchard finds herself at the forefront of a feminist revolution — the new Purple Democratic Alliance — which wins in a landslide. But once in office, she must learn fast while holding on to the qualities that got her there. By turns funny, touching and inspiring, this series will speak to any viewer who ever scoffed at government and thought: I wouldn’t do a bit worse if I were in charge. Starring Jane Horrocks, it premieres Sunday at 9 p.m.

“Shark” (10 p.m., CBS): On a new episode of “Shark,” Sebastian takes an offbeat approach to a case, choosing to prosecute the coach of an ultimate fighting team for the deaths of three fighters who took their own lives after the coach prodded them to take steroids.
