The Tyrannosaurus Rex is known as the king of the dinosaurs, but how did its reign begin? Meet Moros Intrepidus, a 180 lb., deer-sized ancestor to the T-Rex. Learn how the latest in paleontology can now link this small dinosaur to the 19,000-pound Scotty, the largest T-Rex ever discovered.

Hybrids can be bizarre and they can be deadly. We look at two hybrid animals that owe their existence to human interference - the pizzly bear (a cross between a polar bear and grizzly), which has come into being because of global warming, and the killer bee, brought into existence because of the transfer of African bees to South America.

In Snowball, Chris Packham tells the story of the astonishing moment in Earth’s distant past, when almost the entire planet froze – a glistening ‘Snowball Earth’ in the dark void of space. With ice wrapped around the planet to the equator, the chances of life surviving hang in the balance. Earth’s terrifying journey into the deep freeze started with fire, not ice. 800 million years ago, long before the age of the dinosaurs, before there was even animal life, the giant supercontinent Rodinia broke up. Earth’s vast powerful tectonic forces ripped the land apart, kicking off a series of events that resulted in huge amounts of carbon dioxide being sucked from the atmosphere and sending global temperatures plummeting. This plunge into the deep freeze couldn’t have come at a worse time. The very first forms of complex life - the ancestors to the amazing life we see around us today - were evolving but, as the planet froze to the equator, it looked like their days were numbered. Happily, Chris discovers that after 50 million years locked in ice, volcanic eruptions drove a great thaw. Life broke free from the ice and soon made a giant leap, from the microscopic, to the first animals big enough to see and touch.
