Question

Which evolutionary phenomenon is depicted by the sketch given in figure?

• A. Artificial selection
• B. Genetic drift
• C. Convergent evolution
• D. Adaptive radiation

Answer 1

The Correct Option is D

The image illustrates the diverse beak morphology among Darwin’s finches, a prime instance of adaptive radiation.
Adaptive radiation describes the process whereby an ancestor species evolves into numerous distinct species, each specialized for a unique ecological role.
For Darwin’s finches, the ancestral finch species that arrived on the Galapagos Islands diverged into multiple species, developing distinct beak shapes suited to varied diets, including insects, seeds, and fruits.
