Across the world we are seeing the emergence of bacteria that have gone rogue. These are the superbugs, dangerous bacteria that are becoming resistant to our only defence: antibiotics. Horizon meets the scientists who are tracking the spread of these potential killers around the globe, and discovers the new techniques researchers are developing to help defeat these superbugs.
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.
David Attenborough chooses his ten favourite animals that he would most like to save from extinction. From the weird to the wonderful, he picks fabulous and unusual creatures that he would like to put in his 'ark', including unexpected and little-known animals such as the olm, the solenodon and the quoll. He shows why they are so important and shares the ingenious work of biologists across the world who are helping to keep them alive.
Life and Death explores the impact of Darwin’s ideas on our understanding of the meaning of extinction and the interconnections between all life on earth and the environment. Darwin learned many lessons from the giant fossils of extinct animals he found in Argentina and Chile. He eventually revealed to us the unpalatable truth that the logical conclusion to evolution is not perfection but extinction. The extinction of one species creates an environmental niche for new species to fill. Darwin’s theory also gives us vital knowledge we can use to help prolong the existence of our species by respecting the interconnections between all elements of the natural world and the environment. It’s a story in which Darwin’s ideas are taken up with great enthusiasm by his followers throughout the 20th century. But humanity misses one opportunity after another to acknowledge and reduce its destructive impact on the planet. As a result we have set in motion the sixth mass extinction of life on earth. And we are running out of time to do something about it by preserving ecological "hotspots" like certain rainforests which are some of the most productive cradles of evolution. This programme is a warning, but also a celebration, of the knowledge Charles Darwin gave us in his theory of evolution. It confirms that Darwin’s theory continues to inform our understanding of ourselves, our planet and the intricate interconnections between all life on earth.
The migration of the painted lady has long fascinated scientists, artists and nature lovers alike. The longest butterfly migration on earth, it sees millions of these delicate creatures travel from the desert fringes of north Africa, across thousands of miles of land and sea, before settling in the UK. However, the migration has never truly been understood, the mysteries of the painted lady never unravelled - until now.
