On the Alaska Peninsula, where exceptional landscapes are commonplace, a small river attracts attention far beyond its scale. Each year, from summer to early fall, brown bears and salmon gather at Brooks River to create one of North America's greatest wildlife spectacles. As the salmon leap from the cascade, dozens of bears are there to catch them, and thousands of people come to watch in person or on the National Park Service's popular Brooks Falls Bearcam. The Bears of Brooks Falls tells the story of this region and the bears that made it famous.

Charles Darwin arrived at the Galapagos Islands some three centuries after their discovery. Thousands of seafarers had been there before him, but in these islands Darwin found something more enduring than fresh water and tortoise meat. He found nourishment for an idea - an idea so powerful that its implications revised the place of humans in the universe and enriched every facet of science. Darwin tested and refined his idea for decades before he was persuaded to go public in 1859 by publishing The Origin of Species.
