This explains both the origination rates and the extinction rates, as Mendelian genetics and Darwinian evolution explained to us that stressors allow for more mutations and more chance for opportunities to exploit. The takeaway for us should be that ecosystems may be more unstable in a hi-T regime. Ecosystems are the bases for our economy and relatively stable ecosystems are what our modern societies evolved in (else we moved to more stable ecosystems: away from Eastern Med and sub-Sahara).
