Using innovative storytelling techniques, 3D graphics and CGI to bring ancient beasts to life, “When Whales Walked” offers surprising insights into the evolution of these magnificent animals, exploding myths about the path these species took over millions of years.

Caudipteryx was a small feathered dinosaur that couldn't fly, and its fossils have been found in the Liaoning Province of Northeastern China by local farmers tilling the land, resulting in a scientific goldmine for those studying the evolution of birds.

One early croc relative was built like a greyhound, ancient whales really did walk on four legs and the earliest ancestor of the elephant was the size of a rabbit.

Empire of Elephants

Birds arose from feathered dinosaurs — in fact, they are dinosaurs — and went on to colonize the natural world as well as the urban spaces created by humans.

Ornithology researcher, Dr. Jingmai O'Connor's work includes the study of Mesozoic birds, specifically the evolution from non-avian dinosaur to the orinithothoraces, ancestors of today’s birds, as seen in "When Whales Walked: Journeys In Deep Time."

“‘When Whales Walked: Journeys In Deep Time’ dives deep into the fascinating origins of some of the world’s most incredible creatures,” said Bill Gardner, Vice President, PBS Programming and Development. “By exploring the latest scientific discoveries, we bring millions of years of natural history alive in some very unexpected ways. As America’s home for documentary film and the market leaders in science and natural history content, we’re thrilled to partner with an institution like the Smithsonian to showcase these spectacular new breakthroughs in evolutionary history.”

“When we marvel at the wonders of the natural world, like an elephant’s trunk or the size of a blue whale, we rarely ask, ‘Where did that come from?’ It turns out, scientists are finding some truly extraordinary answers,” said Charles Poe, SVP of Production, Smithsonian Channel. “This film will introduce viewers to the surprising ancestors of animals we know and love. We’re very excited to be launching our first partnership with PBS to take viewers on an utterly unique journey to the deep past.”

“‘When Whales Walked: Journeys In Deep Time’ takes us to the frontiers of science,” said Michael Rosenfeld, Vice President of National Production for Twin Cities PBS, who originated the project. “It shows how researchers are using not just paleontology, but genetics, climate science and ecology to fill in the gaps in the story of life. And it’s not just a story of the past—these discoveries carry important lessons for today and even the future.”
