question

On Andros Islands in the Bahamas, populations of mosquito fish, Gambusia hubbsi, colonized a series of ponds. These ponds are no longer connected. However, the environments are very similar except that some ponds contain predatory fish, while others do not. In high predation ponds, selection has favored the evolution of a body shape that enables rapid bursts of speed. In low predation ponds, another body type is favored—one that is well-suited to swim for long periods of time.

choices

  1. Reproductive isolation caused geographic isolation.
  2. Reproductive isolation was not complete.
  3. Allopatric isolation brought about reproductive isolation.
  4. Sympatric isolation brought about reproductive isolation.
