that more down to earth factors could have accounted for past mass
extinctions

Earth history has been punctuated by several mass extinctions rapidly

wiping out nearly all life forms on our planet. What causes these
catastrophic events? Are they really due to meteorite impacts? Current
research suggests that the cause may come from within our own planet --

Flood basalt eruptions are -- he says -- an alternative kill mechanism.
These do correspond with all main mass extinctions, within error of the
techniques used to determine the age of the volcanism.

So maybe they were caused by the impacts?
