Can Science Explain the Origin of Life?

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.

What is the Evidence for Evolution?

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.

What Was The Miller-Urey Experiment?

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.

Builders

David Attenborough returns in this landmark series to his most magical place on earth exploring the Great Barrier Reef aboard the research vessel Alucia. Part 1: Builders David descends beneath the waves at night in the state-of-the-art Triton submersible, the first of its kind to visit the reef. He meets some of the tiny coral animals that built the reef and helped to turn it into an underwater wonderland. He then takes to the skies to witness the vast scale of their endeavour, a living structure that provides a home for thousands of species. Using cutting-edge technology to generate computer scans of the sea floor, David learns that the Great Barrier Reef we know today is much younger than scientists ever imagined. He meets some of the people that have lived alongside it and who have told stories of its origins for thousands of years.

The Ancient Highway

First transmitted in 1965. David Attenborough continues his journey along the Zambezi River. This episode begins at Victoria Falls, the largest waterfall in the world. At the foot of the falls, with its moist climate, a wealth of plants and animals can be found, such as hyraxes. To coax the hyraxes out of hiding, David Attenborough illustrates why taking a dog whistle with you while on an African adventure is a very good idea indeed. Other highlights encountered on the way include an estivating lungfish and a herd of elephants washing and dust bathing at a water hole.Further along his journey David Attenborough explores a Portuguese fortress at Tete, believed to have been built over 400 years ago, and assesses the impact of the then newly constructed Kariba Dam, one of the largest dams in the world, on the displaced Tonga people and surrounding countryside.

There Was No First Human

If you traced your family tree back 185 million generations, you wouldn't be looking at a human, a primate, or even a mammal. You'd be looking at a fish. So where along that line does the first human show up? The answer may surprise you.

Mother's Darlings

For many animals, from lemurs to hummingbirds, the maternal bond is one of the strongest forces in nature. Not only do mothers carry their young everywhere, feed them, and help teach them essential life skills, they're also their primary source of comfort and security.
