What are the primary evolutionary mechanisms that result in the great diversity and adaptation in prokaryotes?
What will be an ideal response?
ANSWER: Genetic variability primarily arises due to mutation. Prokaryotes have approximately 1,000
times more mutations per gene, per unit time, per individual, than do eukaryotes. Natural
selection then works on the large populations that result from rapid reproduction, leading
to rapid adaptation.
