Asked by mustafahaleem about 1 year ago, 4 answers.

It is known that the earth's magnetic field reverses every few millenia. was there any mass extinctions or anything that happened like that at the time.

You mean every few hundred millennia. And no, there is no connection. If any reversals coincided with a mass extinction, the connection is a correlation, not a causation.

As for evolution, perhaps role reversals occurred with cavemen as their women became effected by such pole reversals.
