GPT explains (level =C2; CEFR aligned): Definition of a ‘mass-extinction’ event Palaeobiologists reserve the term mass extinction for relatively brief geological intervals (typically < 3 Myr) during which the global rate of taxonomic loss spikes to many times the long-term ‘background’ rate of extinction. Five such pulses—the “Big Five” of the Phanerozoic—each eliminated ≥ 75 % of marine species. The operative criterion is therefore an extinction velocity orders of magnitude above the statistical baseline, not the body size of the victims, the causal mechanism, nor the absolute number of taxa lost. Framing the concept in rate terms allows direct comparison between episodes separated by hundreds of millions of years and underpins current debates on whether the present anthropogenic biodiversity crisis is already a sixth mass extinction.
