This episode reveals how mammals developed from tiny nocturnal forest dwellers to the dominant form of life on the planet following the death of the dinosaurs. David explains how the meteoric rise of mammals led to an astounding diversity of life and laid the foundations for the ascent of man.

In this episode, Iolo investigates the courtship and nesting behaviour of birds, including the amazing courtship display of great crested grebes at a reservoir near Pontypool, the impressive sky dance of hen harriers in the dramatic Cambrian Mountains, how nuthatch use mud like cement to prepare their nest in a woodland near Harlech, and why long-tailed tits near Newtown are exceptional nest builders. On the Lleyn Peninsula near Trefor, he looks at why one colony of shags nest earlier than any others in Wales, and in Pembrokeshire he finds out where house martins nested before they used our buildings. Iolo also looks at the variety of places birds like to nest, from little ringed plovers on shingle banks along the River Tywi to puffins underground on Skomer.

The second episode of Andrew Marr's exploration of Darwin explores the impact of Darwin’s ideas on society and politics. Darwin’s first port of call on the Beagle was Salvador in Brazil – then a major port for the international slave trade. His experience there confirmed his enlightenment views of liberty and progress and his hatred of slavery. But his theory of evolution that began to take root on that epic voyage would describe a world of conflict, ruthless competition and struggle. It would be taken up and abused by some of the most reactionary movements of the late-19th and 20th centuries. The phrase “survival of the fittest” would help propel Darwin’s theory as a scientific justification for eugenics, enforced sterilisation and genocide. But after the Second World War, Darwin’s theory finds redemption in the United Nations statement on race which confirms Darwin’s long-held view that all humans are members of the same race and deserving of equal treatment. This is further reinforced in the extraordinary work of a small Jewish community in New York who used DNA testing and a voluntary and anonymous form of selective breeding to eliminate a debilitating disease from the Jewish community. DNA testing is the final frontier of Darwin’s Dangerous idea. But the lessons from history suggest that the new choices we face about what to do with the knowledge Darwin has given us when combined with genetics and DNA testing remains a major social and political challenge.

Hummingbirds represent one of nature's most interesting paradoxes - they are the tiniest of birds, yet they qualify as some of the toughest and most energetic creatures on the planet. New knowledge gained from scientists currently making great breakthroughs in hummingbird biology makes this a perfect time to focus on these shimmering, flashing jewels of the natural world. Stunningly beautiful high-definition, high-speed footage of hummingbirds in the wild combined with high-tech presentations of their remarkable abilities help us to understand the world of hummingbirds as we never have before.
