Why did almost all life go extinct 250 million years ago? Why on five other occasions in the geological history has the living world experienced sudden episodes of global mega-death with the majority of species being annihilated? And are humans causing the sixth great mass extinction event in Earth's history? These are among the questions Adam Rutherford explores in these three-part series on extinction. Producer: Andrew Luck-Baker.
