The team set off beneath the waves to explore this spectacular archipelago. It is an exciting opportunity for the team to delve into a world that still largely remains a mystery to science. Venturing down in the Nadir, a specially equipped deep sea submersible, Liz goes in search of an elusive ocean giant, the mola, or sunfish, to understand more about its little-known behaviour in the deep. On the way back to the Alucia, Liz checks in on a playful sea lion population to see how they have been affected by a recent extreme weather event, El Nino. Back on board the Alucia, the team sets sail north for the most remote and inhospitable islands in the Galapagos - Wolf and Darwin. Here, Liz joins the team tagging and tracking hammerhead sharks that school at this location in huge numbers as they try to unlock the secrets of this stunning behaviour. But nothing can prepare the Alucia crew for the power of the ocean in this isolated marine wonderland.
Armed with the latest global scientific research, Chris Packham and Liz Bonnin battle it out to find the definitive answer to the burning question - which are best, cats or dogs? Part 2: Chris Packham and Liz Bonnin present the second of two programmes in which pooches and pussies are put through a number of tests to see which family pet comes out on top. There are five more rounds, concentrating on which animal is easiest to train, communication, which is best at helping reduce people's stress, independence and the big question - do cats and dogs really love their owners? On the search for answers, dog-lover Chris meets a Border Collie which can recognise more than 150 words and Liz meets a cat capable of choosing its own TV channels.
The Miller-Urey experiment was the first attempt to scientifically explore ideas about the origin of life. Stanley Miller simulated conditions thought be common on the ancient Earth. The purpose was to test the idea that the complex molecules of life (in this case, amino acids) could have arisen on our young planet through simple, natural chemical reactions.
