Piers hears from Dr.Tony Heyes, retired physicist and inventor, about what he calls the Adams Event, a time 42,000 years ago when the Earth's magnetic field flipped.

He suggests the extinctions of Australia's megafauna and neanderthals may have been caused by this apocalyptic environmental crisis, as revealed in the rings of an ancient Kauri tree, preserved in a swamp in New Zealand.
