Convergent Evolution

Q.

The process by which organisms with different evolutionary histories evolve similar phenotypic adaptations in response to a common environmental challenge is called?

1. convergent evolution

2. natural selection

3. adaptive radiation

4. non-random evolution

Q.

Evolutionary convergence is development of

1. Common set of characters in a group of different ancestry

2. Dissimilar characters in closely related groups

3. Common set of characters in closely related groups

4. Random mating

Q.

Give one example of analogy in plants.

Q.

Resemblance between widely different groups due to a common adaptation is known as

1. Parallel evolution

2. Divergent evolution

3. Convergent evolution

4. Retrogressive evolution
