A population of rabbits inhabits an ecosystem. A river that flows through the ecosystem changes course, isolating a small population of rabbits from the larger population. Which of the following will most likely happen to these two populations of rabbits over time?
A. The two populations will develop identical changes in their genome, which will cause both populations to develop identical favorable traits.
B. The two populations will develop different gene mutations, which will eventually lead to the two populations becoming separate species.
C. The two populations will regularly reproduce with each other, which will increase the gene flow between the populations.
D. The two populations will only pass on favorable traits to their offspring, which will cause the populations to become genetically identical.
