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.

Darwin's theory of biological evolution helps us understand how simple life forms can give rise to complex lifeforms, but how did the first reproducing creatures come about? The origin of life needs its own explanation.
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?
You've probably heard about GMOs or Genetically Modified Organisms but what exactly is a gene and what does it mean to modify the genes of a plant or animal?
Evolution is often considered a complex and controversial topic but it's actually a very simple concept to understand. Watch this short animation to see how evolution works.
Natural Selection is one of the main concepts found within the theory of evolution. It was discovered by Charles Darwin and Alfred Russel Wallace though Darwin championed the idea in his book "On the Origin of Species".
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.
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 documentary series gives a bird's-eye view of South America, as condors soar along the Andes, scarlet macaws explore the heart of the Amazon and hummingbirds and vultures see the continent's greatest sights. It is a journey that includes Machu Picchu, the Nasca Lines and the cities of Rio de Janeiro and Santiago. In Patagonia, giant petrels shadow killer whales as they hunt seals by stranding their huge bodies on the beach. At Iguassu Falls, dusky swifts dive through the cascades to huddle in communal roosts while hummingbirds bathe below. In a secret Andean location, condors soar in flocks over 40-strong and scavenge on casualties from herds of fighting guanacos. Elsewhere, a mother condor gently pushes her youngster to the edge of a 200-metre cliff, as flight school begins. Deep in the Amazon, macaws seek medicinal clay. They are joined by a host of secretive jungle animals, including spider monkeys and tapirs, all after the same remedy. In Peru, condors soar over fighting sealions waiting for casualities and on a mass exodus north, birds converge on the Panama Canal. In Costa Rica, black vultures descend on turtles as they lay their eggs in the sand and pick off the eggs that ping-pong through the air.

David Attenborough attempts to animate the life of the ichthyosaur whose 200-million-year-old fossil remains were found on Britain's Jurassic coast. Using state-of-the-art imaging technology and CGI, the team reconstruct the skeleton and create the most detailed animation of an ichthyosaur ever made. Along the way, they stumble into a 200-million-year-old murder mystery - and only painstaking forensic investigation can unravel the story of this extraordinary creature's fate.

In this episode we explore the remarkable adaptations of two creatures that have evolved to survive the most challenging of conditions and seem to defy the laws of nature.

David Attenborough takes a breathtaking journey through the vast and diverse continent of Africa as it has never been seen before. (Part 5: Sahara) Northern Africa is home to the greatest desert on Earth, the Sahara. On the fringes, huge zebras battle over dwindling resources and naked mole rats avoid the heat by living a bizarre underground existence. Within the desert, where the sand dunes 'sing', camels seek out water with the help of their herders and tiny swallows navigate across thousands of square miles to find a solitary oasis. This is a story of an apocalypse and how, when nature is overrun, some are forced to flee, some endure, but a few seize the opportunity to establish a new order.
By telling the story of our organs, this documentary makes us aware of an evolutionary timeline. Our nose is 40 million years old, our coccyx 25 million, our fingers 370 million, while our chin is only 200,000 years old!
