Question

a scientist proposes that certain species of bacteria have an unusually high rate of evolutionary change, allowing them to develop new adaptations relatively quickly. which observation about the species most strongly supports the scientists proposal?

a.the bacteria have a high rate of mutation

b.the bacteria have a low rate of mutation

c.the bacteria reproduce asexually

d.the bacteria have circular dna

Explanation:

Mutation is the source of genetic variation for evolution. A high - mutation rate provides more genetic changes, which can lead to new adaptations more quickly. A low mutation rate would limit genetic variation. Asexual reproduction and circular DNA do not directly relate to the rate of evolutionary change as strongly as the mutation rate.

Answer:

A. The bacteria have a high rate of mutation
