Answer:

(A) speciation.

Explanation:

Shrinking of water bodies and development of deserts since the Pleistocene ice age produced new vacant niches that could be inhabited by organisms such as fishes. Production of new isolated streams, ponds, and springs allowed the fishes to occupy these new water bodies. Accumulation of genetic variations to become adapted to their new habitat resulted in the evolution of several new species of fishes with many different genetic traits. This represents speciation due to geographical isolation.
