Lifepulse - a Natural Thriller · BBC Four · Friday, December 28

A spectacular musical celebration of life, capturing evolution in all its glorious diversity, and the rhythms of nature in all its beauty, delight, and horror. From the raging furnace of volcanoes to frozen glaciers, deserts and humid rainforests, Lifepulse is a dramatic visual journey, starting in primeval chaos and ending with the rise of the primates and of man, who now threatens the environment that nurtured him. A specially composed soundtrack by the Startled Insects is enhanced by the use of natural sounds.
