Zion's dwindling cougar population traces its roots to the late 1920s, when the park's management made efforts to increase visitation.

Bonobos have a playful, gentle manner that is often reminiscent of human beings at their best. Our common primate ancestor lived six million years ago.

The Smart and Swinging Bonobo

Civil war has threatened the existence of wild bonobos, while new research on the hypersexual primates challenges their peace-loving reputation

Sue Savage-Rumbaugh (with Kanzi in 2003) says her bonobos can communicate with her and each other using more than 348 symbols.

Speaking Bonobo

Bonobos have an impressive vocabulary, especially when it comes to snacks

What do dancing and scientific research have in common? "Creativity," says Jarvis (performing in high school in the early 1980s), and "hard work."

Song and Dance Man

Erich Jarvis dreamed of becoming a ballet star. Now the scientist's studies of how birds learn to sing are forging a new understanding of the human brain

Claudine Andre, founder of Lola Ya Bonobo (Bonobo Paradise) sanctuary, rescues about ten of the endangered animals per year.

Wild Things: Life as We Know It

Killer whales, trap-jaw ants and dinosaurs

Anthropologists recently found fossils of Paranthropus robustus, also called robust australopithecines, in an excavation site in South Africa. Paranthropus coexisted with human ancestors Homo habilis and Homo erectus as recently as 1.5 million years ago. Some anthropologists had believed that Paranthropus' limited diet caused its extinction, but new evidence from the fossils suggests that Paranthropus had a varied diet that included both hard and soft plants as well as herbivores.

Frozen in Time

Glaciers in the Pacific Northwest have recorded hundreds of years of climate history, helping researchers plot how quickly the planet is warming

Once extracted, labeled and bundled, the cores are carefully airlifted to the safety of the lab. Only there will the ice's true secrets be revealed.
