Would we exist if Earth’s magnetic field hadn’t collapsed 500m years ago?

The Earth’s magnetic field is vital for life – without it, the Sun’s radiation would sterilize the planet. But a new study suggests we wouldn’t be here at all if that magnetic field hadn’t almost completely collapsed half a billion years ago.
