As the days shorten and the temperature drops, the inhabitants of Nunavik, Quebec prepare to face the approaching arctic winter. Watch as muskoxen fatten up, ptarmigans hunt for berries, and Inuit make use of the last warm days of the year.
Professor Alice Roberts explores the story of human evolution, revealing how a humble African ape became a successful global species. With daring parkour athletes and life-size primate animatronics, Alice explores the greatest leaps in our evolution by conjuring fire and re-enacting how we spread across the globe.
This episode continues the study of mammals, and particularly those whose young gestate inside their bodies. Attenborough asks why these have become so varied and tries to discover the common theme that links them. Examples of primitive mammals that are still alive today include the treeshrew, the desman and the star-nosed mole. Insect eaters vary enormously from the aardvark, giant anteater and pangolin to those to which much of this programme is devoted: the bats, of which there are nearly 1,000 different species. These took to flying at night, and its possible that they evolved from treeshrews that jumped from tree to tree, in much the same way as a flying squirrel.
African penguins were once the most numerous sea bird on the continent--until their population was decimated by human activity. Visit a rare colony at South Africa's Boulders Beach and see how these master divers and ocean hunters are staging a remarkable revival.
