Mass extinctions cause the loss of many species,no matter how well adapted those species were before the extinction.Why might previous adaptations NOT help a species survive a mass extinction?

Question

Quizplus · Accepted Answer

Mass extinctions are caused by rapid environmental changes that occur too quickly for species to adapt to them. Therefore, previous adaptations may not be effective in helping a species survive a mass extinction.

Answer: B and C are incorrect. 
 Ongoing continental drift and interbreeding among species do not necessarily affect their ability to adapt to environmental changes. Additionally, adaptive radiations are a product of adaptations, not a competing force.

Answer: D is incorrect. 
 Mass extinctions affect all types of organisms, regardless of their previous adaptations. The survival of certain groups is often due to chance or luck, and not necessarily their level of adaptation.
