BBC Natures Wonderlands Islands of Evolution 1of3 Hawaii A New Eden 720p x264 HEVCguy

Three-part series in which Professor Richard Fortey investigates why islands are natural laboratories of evolution and meets some of the unique and remarkable species that live on them. Examining some of the crucial influences on natural selection that are normally overlooked - like geology, geography, isolation and time - the series reveals that there is much more to evolution than 'survival of the fittest'. Charting the lifecycle of islands - from their birth and colonisation to the flowering of evolutionary creativity that often accompanies their maturity, and what happens when an island grows old and nears its end - Fortey encounters wild lemurs in the rainforest of Madagascar, acid-resistant shrimps in the rock pools of Hawaii, and giant wolf spiders in Madeira as he searches for the hidden rules of island evolution.

In the first episode, Fortey is on Hawaii to investigate how life colonises a newly-born island. The most remote island group in the world, by some estimates only one new species successfully colonised Hawaii every 35,000 years - yet the Hawaiian Islands teem with a great diversity of life. In search of the evolutionary secrets of how one species becomes many, Fortey encounters beautiful honeycreeper birds whose evolution rivals that of the Darwin's famous finches; carnivorous caterpillars who now can't eat leaves; and giant silversword plants that thrive in parched volcanic soil at 10,000 feet.
