Teacher note: a rapid change in the environment or a catastrophe has been involved in many extinctions as there is not enough generation time for populations to adapt. Language precision to reinforcing misconceptions. 63 8 Unit 8 Lesson 13 3 Species that have gone extinct often have good adaptations and are unlucky or in the wrong place at the wrong time. Species that have gone extinct have good adaptations for the current environmental conditions, but when the environment changes too rapidly the population is unable to adapt are in the wrong place at the wrong time.
