Question

select the correct answer. a particular species of fish were split by the formation of the isthmus of panama a long time ago. the fish developed changes in their genes to adapt to the new environment and became two different species. what is this process called? a. allopatric speciation b. sympatric speciation c. gametic isolation d. behavioral isolation e. mechanical isolation

Explanation:

Allopatric speciation occurs when a population is geographically separated (like by the Isthmus of Panama) and evolves into distinct species. Sympatric speciation is without geographic separation. Gametic, behavioral, and mechanical isolation are pre - zygotic barriers, not speciation processes. So the correct answer is A.

Answer:

A. allopatric speciation
