Making North America | Life

Tonight at 9p.m. on WSKG TV-  NOVA Making North America | Life, tells the intertwined story of life and the landscape in North America. Host Kirk Johnson travels to the North Dakota Badlands and the southern Utah desert to answer the riddle of why so many dinosaurs flourished there, and to see traces of the asteroid that wiped them out. With the dinosaurs gone, mammals flourished and the ancient forests became home to some of the earliest primates. Kirk unravels the mystery of why they too disappeared, leaving North America mostly primate-free until the arrival of humans millions of years later. How did life emerge on our primeval continent? Why was North America home to so many iconic dinosaurs like T. rex? And how did a huge sea filled with giant marine reptiles end up covering Kansas?
