Take an epic voyage over the remote island nation of New Zealand, the last habitable landmass to be discovered on the planet. No bigger than the state of Colorado, this small country offers an incredibly diverse landscape view that changes dramatically with each mile. From snow-capped mountains to sandy beaches, and from the glacier-carved Fiordland National Park to the crater lake of Mount Ruapehu, New Zealand is a land of extremes. It's a place where fire clashes with ice and people are always pushing the limits.

The next instalment describes the move from water to land. The fish that did so may have been forced to because of drought, or chose to in search of food. Either way, they eventually evolved into amphibians. Such creatures needed two things: limbs for mobility and lungs to breathe. The coelacanth is shown as a fish with bony fins that could have developed into legs, and the lungfish is able to absorb gaseous oxygen. However, evidence of an animal that possessed both is presented in the 450 million-year-old fossilised remains of a fish called a eusthenopteron. Three groups of amphibians are explored.
While the immense ecosystem of the Kalahari is characterized by its harsh conditions, it also offers a wealth of resources to the native wildlife. From the burrows of nocturnal bat-eared foxes to the massive colonies of harvester ants, the region provides habitats for a vast array of life.
The human eye is an amazing mechanism, able to detect anywhere from a few photons to a few quadrillion, or switch focus from the screen in front of you to the distant horizon in a third of a second. How did these complex structures evolve? Joshua Harvey details the 500 million year story of the human eye.
Investigates the greatest vanishing act in the history of our planet - the sudden disappearance of the dinosaurs 66 million years ago. Experts suspect that the dinosaurs were wiped out after a city-sized asteroid smashed into the Gulf of Mexico causing a huge crater. But until now, they haven't had any proof. In a world first, evolutionary biologist Ben Garrod joins a multi-million pound drilling expedition into the exact spot the asteroid hit to get hard evidence of the link. The team overcomes huge obstacles as it attempts to drill 1,500 metres beneath sea level to pull up rock from the Chicxulub crater.
