Forget what you think you know about pigs. These remarkable animals have talents we're only beginning to understand. See how pigs have conquered nearly every habitat on Earth, thanks to their remarkable senses, intelligence, and adaptability. From the islands of Indonesia to the beaches of the Bahamas to the frozen tundra of Siberia, meet eight-inch pygmy hogs, cheetah-avoiding warthogs, domesticated pigs with super senses, and more.
The most extreme and wild parts of New Zealand are in the South Island, which lie towards Antarctica, in the path of the tempestuous 'roaring forties'. This is home to some of the most rapidly rising mountains in the world, the Southern Alps. From hyper-intelligent parrots to sinister snails with teeth and magical constellations of glow-worms, this is the story of New Zealand's wildest places and its most resilient pioneers, all of whom must embrace radical solutions to survive.
David Attenborough visits archaeological sites where fossils were found illustrating the origins of life on earth, in the ocean. For long, evolution worked very slow and species remained primitive, mostly single-cell, alter fractal. Only the invention of sexual reproduction kick-started genetic diversification.
Chris and Martha discover which of our tagged bees have survived over the midsummer week - a frenetic nectar and pollen gathering period - and if they have collected enough food at this critical time to see them through the winter. With the help of Prof Adam Hart they will also explore the queen's remarkably deadly mating ritual and look at how bees can help us medically and how we can help them.
Hybrids can be bizarre and they can be deadly. We look at two hybrid animals that owe their existence to human interference - the pizzly bear (a cross between a polar bear and grizzly), which has come into being because of global warming, and the killer bee, brought into existence because of the transfer of African bees to South America.
