Sir David Attenborough chooses his favorite recordings from the natural world --from the song of the largest lemur to the song of the humpback whale to the song of the lyrebird-- that have revolutionized our understanding of song. The science of song had been transformed by Charles Darwin’s theory of sexual selection: singing is dangerous as it reveals the singer’s location to predators, but it also offers the male a huge reward, the chance to attract a female and pass on genes to the next generation. Today, new science in the field of birdsong is transforming those long-held ideas.
Scientists are discovering that, in fact, in the majority of all songbird species, females sing - and it is only now they are being properly heard. Through this revelation and others, we can understand that animal songs are marvellous examples of the spectacular survival strategies that species have developed.

Hitler’s rise to power was a unique moment in history. Germany suffered a humiliating defeat in WWI; now it's crippled by massive war reparations. Hitler offers a scapegoat: the Jews.

There they are either worked to death, starved or executed. But just how much did the rest of the world know of what was going on?

The film explores the revolutionary gene-editing tech now giving humankind the freedom to redraw the blueprint of biological life itself. We investigate not only the tremendous potential the technology holds, whether in the fight to eliminate diseases or in transforming agriculture to adapt to unprecedented climate extremes, but also probe the inherent risks involved and the potential for widespread abuse, dangers that could take our future down a very dark, dystopian path.
