(2013) Explore the history of life from its humble beginnings as single-celled organisms, to its great blossoming and proliferation, which took place over the course of eons. With the help of state of the art computer graphics, the world's foremost paleontologists and biologists help unravel the greatest mysteries of life. The Landing Life, which first inhabited the seas and then land, is an amazing story. Through investigation of ancient trailblazers such as Tiktaalik, we learn the gradual process by which lungs and legs evolved, and how the creatures of the seas eventually conquered the land.
