Mass extinctions may not threaten distant futures, but they are decidedly unpleasant for species caught up in the throes of their power.
Stephen Jay GouldThe history of life is more adequately represented by a picture of 'punctuated equilibria' than by the notion of phyletic gradualism. The history of evolution is not one of stately unfolding, but a story of homeostatic equilibria, disturbed only 'rarely' (i.e. rather often in the fullness of time) by rapid and episodic events of speciation.
