Answer #1

no extinction, but evolution.

Answer #2

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.

Answer #3

soo I wonder…how is there evolution during the reversals, seeing as during a reversal almost all of the suns deadly radiation is let into the atmosphere..?

Answer #4

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