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.

Bees and ants work selflessly toward a common goal. Bonobos maintain social harmony through sex, while meerkats organize themselves with military-level discipline. What do these creatures all have in common? The basic recognition that their survival hinges on an ability to work and live together.
Man has explored land, the oceans surface, and large parts of the solar system, and in the 21st century we are just beginning to explore the depths of the Pacific Ocean. We yearn to unravel the mysterious Pacific but she does not give up her secrets willingly.
The second episode of this unique scientific study reveals the wild side of pet cats. Using GPS trackers and cat cameras, they show how these felines transform from pampered pet to purring predator as soon as they leave the cat flap. Liz Bonnin and some of the world's top cat experts put Ozzy and Smudge under surveillance to find out who is king of the street and reveal why, no matter how hard we try, we can't keep our cats' hunting instincts under control.
The journey begins on the Galapagos' west side at the youngest and most volcanically active islands in the archipelago, Isabela and Fernandina, which are home to a richly diverse wildlife scene. Here, Liz and the team journey into the clouds above Wolf, the tallest volcano in the Galapagos, where they join a group of biologists hunting for the elusive pink iguana, which teeters on the edge of extinction. But how and why did it come to live on the top of a volcano? Back on the research vessel, Liz boards Alucia's Triton submersible to descend a kilometre into the ocean abyss in search of a new species hiding in the darkness. Liz also travels to one of the most remote locations in the Galapagos, Alcedo Volcano, in search of the largest population of giant tortoises. Plagued by drought in recent months, scientists are keen to find out how this prehistoric species has fared. Finally, Liz helps out with a groundbreaking science experiment to x-ray marine iguanas that have so far stunned the scientific community with a new mutation. As with all life on these remote islands, the key to survival is adaptation.
The Siamese fighting fish is so aggressive it will fight its own reflection until it is exhausted. Recent research shows that the fighting behaviour varies and depends on the personality of the fish! Male kangaroos were once pitted against humans in the boxing ring, with the most impressive male kangaroos being solid blocks of muscle with a kick that can kill. Why do they fight and what skills must a winner have?
