NOVA goes beyond the wagging tails and floppy ears to reveal surprising insights into the origin and evolutionary strategy of our canine companions. From a wolf research facility in rural Indiana to New York’s Westminster Dog Show, you’ll discover some amazing dog facts. Did you know the Saluki can beat any other mammal on earth in a three-mile race? That dogs developed spots for a specific reason? And that their evolution is helping us learn about our own?

NOVA explores the search for extraterrestrial life. The program describes the Search for Extraterrestrial Intelligence (SETI), a program that scans star systems for radio transmissions from advanced extraterrestrial civilizations and introduces the Drake equation, created by SETI founder Frank Drake, which attempts to quantify the probability of intelligent life in the Milky Way galaxy.

NOVA reports on the different ways scientists explain how life emerged on Earth. The program relates the discovery of extremophiles—bacteria that thrive in harsh subterranean and deep ocean environments similar to those believed to have existed on primitive Earth and describes an attempt to determine when life began on Earth by searching rock formations in Greenland for higher-than-expected ratios of carbon 12 to carbon 13 (in ratios currently only known to be created by life processes).
