David Attenborough asks three key questions. How and why did Charles 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? David concludes that we now understand why there are so many species, and why they are distributed the way they are. But above all, Darwin has shown that we are not set apart from the natural world and do not have dominion over it. We are subject to its laws and processes, as are all other animals on earth to which, indeed, we are related. Presented by David Attenborough. Produced by Sacha Mirzoeff.
