The End of the Mammoth. Just 11,000 years ago, at the end of the last Ice Age, some veryweird and wonderful giant beasts roamed the planet. Woolly mammoths, sabre-toothed tigers, giant wombats and armadillos were commonplace on nearly all continents, but within 400 years they were gone.
Peter Evans investigates the end of the mega fauna and talks to one researcher whose theory that a single, deadly virus wiped them out, is causing waves amongst the mammoth hunters.
