The discovery of biological evolution is among the most significant scientific findings of the last 200 years. It has lead us to thousands of new discoveries and is greatly expanding our understanding of the natural world.
Issues of genetics and DNA are constantly cropping up in the news from food production and health, to legal cases and ethics. We hear about DNA in movies like Jurassic Park and X-men, we learn bits and pieces about it from TV shows like Dexter and and CSI, but what exactly is DNA, and how does it work?
Biologists teach that all living things on Earth are related. Is there any solid evidence to back this claim? Join us as we explore the facts! We start with a close look at the origin of whales from land mammals, and then touch on the origins of several other critters, including our own species.
The Miller-Urey experiment was the first attempt to scientifically explore ideas about the origin of life. Stanley Miller simulated conditions thought be common on the ancient Earth. The purpose was to test the idea that the complex molecules of life (in this case, amino acids) could have arisen on our young planet through simple, natural chemical reactions.

Armed with the latest global scientific research, Chris Packham and Liz Bonnin battle it out to find the definitive answer to the burning question - which are best, cats or dogs? Part 2: Chris Packham and Liz Bonnin present the second of two programmes in which pooches and pussies are put through a number of tests to see which family pet comes out on top. There are five more rounds, concentrating on which animal is easiest to train, communication, which is best at helping reduce people's stress, independence and the big question - do cats and dogs really love their owners? On the search for answers, dog-lover Chris meets a Border Collie which can recognise more than 150 words and Liz meets a cat capable of choosing its own TV channels.
Marine invertebrates are some of the most bizarre and beautiful animals on the planet, and thrive in the toughest parts of the oceans. Divers swim into a shoal of predatory Humboldt squid as they emerge from the ocean depths to hunt in packs. When cuttlefish gather to mate, their bodies flash in stroboscopic colours. Time-lapse photography reveals thousands of starfish gathering under the Arctic ice to devour a seal carcass. A giant octopus commits suicide for her young. A camera follows her into a cave which she walls up, then she protects her eggs until she starves. The greatest living structures on earth, coral reefs, are created by tiny animals in some of the world's most inhospitable waters.
New England is the stage for the most incredible colour change on earth, when the vivid greens of summer give way to the gold’s and reds of autumn. This film reveals how this vibrant fiesta is created by the battles between the trees and the forests' inhabitants. Moose, chipmunks, rattlesnakes and a bizarre mixture of caterpillars all play a crucial role, but surprisingly the forest itself was made so colourful thanks to a combination of hard work by beavers, ants and humans.
Footage of wildlife inhabiting underwater kelp forests, including thousands of giant cuttlefish spawning along a restricted area of rocky reef off the south coast of Australia. Males outnumber females 11 to one, which leads to fierce competition. Larger males use brute force to drive off competition, while their smaller rivals use deception by mimicking the appearance of females. The programme also features tiger sharks hunting for green turtles in fields of seagrass and spider crabs trying to avoid predators while they shed their shells.
