David Attenborough asks three key questions: how and why did Darwin come up with his theory of evolution? Why do we think he was right? And why is it more important now than ever before?

The cuckoo is a cheat, a thief and killer. Just how does this traditional indicator of Spring trick other birds into accepting its eggs and why do the duped foster parents work so relentlessly to feed a chick that isn't their own? In CUCKOO, unique archive footage is combined with astonishing new photography and the latest scientific findings to solve a puzzle which - as narrator David Attenborough explains- has perplexed nature-watchers for thousands of years.

Earth: The Climate Wars is a thorough and definitive guide to the history of climate change. Three one hour programmes tell the gripping and at times surprising tale of how scientists discovered global warming – the defining challenge of the 21st century. The series asks how scientists went from thinking a new ice age was on the way just 35 years ago, to believing that global warming is the real threat. If scientists were so wrong then, how can we be so sure they’re right today?

In this powerful three-part polemical series, Dawkins explains who Charles Darwin was, how he developed his theory, what it is, and why it matters. He reveals how Darwin changed forever the way we see ourselves, the world and our place in it, and hopes to convince us that "evolution is a fact, backed by undeniable evidence".

Neanderthals once dominated ice age Europe, but then they disappeared shortly after modern humans arrived on the Continent. What happened to them? For 150 years scientists have been puzzled by the state of our closest relatives. They’ve looked at the archaeological evidence from every angle. Now they’ve turned to DNA in the most ambitious genetic research projects ever attempted,and a new idea is taking route. Is it possible that Neanderthalls live on in us all?

In 1859, Darwin gave us a bold and brilliant idea - evolution by natural selection. But there was so much he did not - could not - know about the workings of evolution. Ever since, other scientists have held his ideas up to scrutiny, and tried to fill in the gaps in evolution theory. Biologist Armand Leroi charts 150 years of scientific endeavour and explores the fall, renaissance and ultimate triumph of Darwin’s ideas.

Welcome to Astrophysics Indiana Jones style! BLAST! is a spectacular and suspenseful story of space exploration. Five-time Emmy winner Paul Devlin, follows his brother, Mark Devlin, Ph.D. to 5 continents, from the Arctic to the Antarctic to launch a revolutionary new telescope on a NASA high altitude balloon to unlock the evolution of the Universe. From catastrophic failure to transcendent triumph, their adventure reveals the surprising real life of scientists.

Since the earth was created 4.5 billion years ago the planet has been struck by a series of catastrophes. Each one pushed life to the edge of extinction - but from disaster comes new life. While the dominant species on the planet were wiped out hardier creatures survived and moved into the vacuum left by the extinction. These creatures then took over the planet until they themselves fell to another mass extinction.
