"Magnetic reversals are part of the cycles scientists have determined existed over the 4.5 billion years of the Earth’s existence. They range from the most ancient, the Devonian, to the Holocene, from 10,000 years ago to the present. “At least twelve (magnetic) reversals can be linked to extinctions and climatic deterioration during the last three million years alone,” says Felix.

Significantly, the aftermath of magnetic reversals are linked to the emergence of new species in ways that Charles Darwin never knew or dreamed of. What we call “evolution” is far more likely the result of magnetic reversals."
