Question

Which of the following factors influences the process of adaptive radiation resulting in rapid speciation the least?

• A. Genetic drift.
• B. Migration to a new area with appropriate resources and few competitors.
• C. Ecological niches vacated by extinction.
• D. The adaptive radiation in a group of organisms that another group of organisms use as a food source.

Answer 1

The correct option is A Genetic drift.

Genetic drift is a sudden alteration in the frequency of an allele due to a natural calamity. Where a certain variation may out number the other. Adaptive radiation is a gradual process to optimally utilize the resources in a habitat, to prevent extinction due to competition

So, the correct answer is 'genetic drift'
