Step 1
Which evolutionary concept demonstrated in the diagram?
Answer
The diagram illustrates a clear progression of phenotypic changes in a population over multiple generations, showcasing variations among individuals that arise in response to environmental pressures. This is characteristic of divergent evolution, where different species evolve from a common ancestor, adapting to various niches and exhibiting increased differences over generations. Hence, the correct answer is (B) Divergent evolution.
