In her debut as co-host of The Nature of Things, Sarika Cullis Suzuki travels back in time to solve the evolutionary mystery of the walking whale

Whales have always fascinated us. We are dazzled by their size, power and intelligence. The largest creature that has ever lived is the stuff of our legends, myths and stories. But how and why did mammals that breathe air end up as ocean going giants?  

Sarika joins top paleontologists and whale researchers on a search for answers that takes her from tropical waters of the Caribbean Ocean to the desolate Egyptian desert. Their journey turns up a 50-million-year old evolutionary smoking gun in a box of prehistoric bones and the astonishing remnant of their prehistoric past that modern whales still carry in their bodies. 

In the Sahara, the otherworldly Valley of the Whales is the largest graveyard of ancient whales on the planet. There Sarika comes face to face with animals known as the God of Death and King Lizard and discovers the role they play in the evolution of the whale. 

Whales have been called the poster child for evolution. Their story is one of the strangest evolutionary puzzles on the planet. With stunning CGI and enough twists and turns for Sherlock Holmes, The Mystery of the Walking Whale is a detective story full of passionate scientific sleuths, strange turns, mind blowing discoveries and some big surprises.
