10. The evolution of Darwin's finches is an example of a. equilibrium. c. stabilizing selection. b. speciation. d. artificial selection.

B) speciation.

Explanation:

The Galapagos island is known for the different varieties of finches (species of birds) which could be distinguished on the basis of different beak shapes and size.

This is the result of the selection pressure which led to the divergence of the species on the island through a mechanism called adaptive radiation.

Since the adaptive radiation leads to the formation of different species on the same island, the process of formation species is known as the speciation.

Thus, speciation is the correct answer.
