Nature

A visit to arguably the most famous archipelago on Earth, the Galapagos. It's home to a myriad of bizarre and unique creatures, endemic to these islands - but how did they get here and what is the key to these extraordinary islands that allows them to thrive? The programme reveals that this key holds not just the secret to life here, but also to how Darwin was able to leave with the ideas that would revolutionise biology.

It really is a big bad world out there. So what happens if you are the little guy? This film tells the epic survival stories of the world's smallest animals. To make a living, these tiny heroes have evolved extraordinary skills and achieved mind-boggling feats. From the animal kingdom's greatest artist to the tiny creatures that provide us with so much of the air we breathe, we discover what it takes to be a miniature miracle.

We love nature and all its glorious diversity. Some creatures we admire for their deadly beauty, others because they are cute, but for some it's hard to figure out exactly why we like them so much, perhaps it's a quirk. How do you decide nature's weirdest animal? Is it the sloth that hangs upside down and moves so slowly that moss grows in its fur? Is it a sea pen that sits rooted to the seabed in endless darkness and emitting its own glow? Could it be carnivorous snails that leave the ocean to digest dead creatures on the beach, finches that drink blood, or the tarantula that keeps a frog as it's pet. But with nature's endless variety, which is the weirdest? We can't decide. Can you?

Sam Neill explores humanity's long-term future - a future where we make new homes for ourselves on other worlds as we flee from the slow but inevitable death of our sun.

The open arenas of grassland and desert make up half of all land on our planet. In these exposed habitats, predators like cheetahs, bald eagles and lions can usually see their prey. But it works both ways: their prey can see them too. With nothing but open vistas, the element of surprise is hard-won, and predators must make their own opportunities.

Life goes to extraordinary lengths to survive this immense realm. A 30 tonne whale shark gorges on a school of fish and the unique overhead heli-gimbal camera reveals common dolphins rocketing at more than 30km an hour. Descending into the abyss, deep sea octopus fly with wings and vampire squid use bioluminescence to create an extraordinary colour display. The first ever time-lapse footage taken from 2,000m down captures eels, crabs and giant isopods eating a carcass, completely consuming it within three hours.
