b. species remain stable for long periods but evolve quickly during short events
c. species never change once they appear in the fossil record
d. species evolve only when humans interfere with the environment

Explanation:

El equilibrio acelerado es una teoría de la evolución que sugiere que las especies permanecen estables durante períodos largos de tiempo (equilibrio) y luego experimentan cambios rápidos (acelerados) durante eventos cortos, como cambios ambientales drásticos.
