The Namaqua rock fig is known as the rock splitter. It's not just a testament to its ability to withstand the dry conditions, but a literal tribute to its powerful root system, which extends 200 feet into the Earth in search of water. Besides the army of wildlife who rely on it for survival, the rock splitter has a unique relationship with its own species of miniature wasp that help pollinate its tiny flowers. As temperatures soar each passing year, this ultimate survivor reaches deeper to squeeze every drop of water from the parched land.

The second episode of the documentary series takes a look at bizarre and extraordinary feathered dinosaurs, many of which have only just been discovered. These feathered beasts are revolutionising our understanding of life on Earth as they blur the boundaries between what we know of dinosaurs and birds. China sits at the heart of the feathered dinosaur discoveries and is the home of one of the most unusual discoveries on Earth: the epidexipteryx. Only the size of a pigeon, this predator was the most bird-like of any dinosaur and is the first known case of ornamental feathers. But feathers were not just confined to the small. From caudipteryx to sinosauropteryx and the 8-metre-long gigantoraptor, feathers may have been used for flight, for insulation or even to intimate and attract. These dinosaurs not only hint at how animals might have developed flight, but also suggest that dinosaurs may still live among us today - as birds.
