Which of the Following is Least Likely to Be a Cause

Question

Which of the following is least likely to be a cause of extinction?  
A) Asteroid impact
B) Human activity
C) Adaptive radiation
D) Continental drift
E) Climate change

Accepted Answer

Adaptive radiation is a process by which new species evolve from a common ancestor due to changes in the environment, which leads to diversification. It is not likely to cause extinction as it increases the number of species rather than causing their decline or elimination. The other options, such as asteroid impact, human activity, continental drift, and climate change, can all play a significant role in causing extinction.
