Matthew has discovered a new species of fish. During the summer months, the male fish separate themselves from the female fish and swim to cooler waters. During one summer, a volcano erupts and the molten rock forms a barrier preventing the male and female fish from reuniting. Matthew has discovered a new species of fish. During the summer months, the male fish separate themselves from the female fish and swim to cooler waters. During one summer, a volcano erupts and the molten rock forms a barrier preventing the male and female fish from reuniting.

• The fish would become extinct as they would not be able to reproduce.
• The species would not be affected by the barrier.
• The male fish would begin to produce eggs and sperm.
• The fish would develop legs and walk across the barrier.

A mountain seperates a population of mice into two distinct eastern and western populations. The eastern area is inhabited by owls, which hunt at night. No owls live in the western area. Over time, the eastern population of mice will MOST LIKELY

• change over time and become less active at night
• become more active at night
• remain identical with the western population
• grow stronger claws and teeth to better fight the owls
