Evolution led to certain fishes, such as lung fishes to adapt to terrestrial mode of life. these fishes were the ancestors of modern amphibians. which evolutionary mechanism is represented by this example?

a. convergent evolution
b. adaptive radiation
c. sympatric evolution

The correct answer is-

A. Convergent evolution.

Convergent evolution can be described as evolutionary process by which organisms independently evolve similar characteristics due to adaptation in the similar environmental conditions.

As per the information given in this question, lung fishes adapted to terrestrial mode of life and considered as the ancestors of modern amphibians.

Amphibians also came into existence by adapting to terrestrial mode of habitat and they also developed lungs for respiration on land.

Thus, it represents the example of Convergent evolution.

Therefore, option A) is the right answer.

equal distribution i think.

the answer is c.) there is a warm front in region a and a stationary front in region b.
