Question

what does the term stasis refer to in punctuated equilibrium? a period of very little change in a species. a phase of extinction in a species. a stable environment leading to gradual changes. a sudden mutation causing rapid evolution.

Explanation:

In punctuated equilibrium, 'stasis' refers to long periods where a species undergoes minimal evolutionary change. Option A matches this definition. Option B is incorrect as stasis is not about extinction. Option C describes gradualism (not punctuated equilibrium's stasis). Option D refers to the rapid change (punctuation) phase, not stasis.

Answer:

A. A period of very little change in a species.
