Question

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

• A. convergent evolution
• B. natural selection
• C. adaptive radiation
• D. non-random evolution

Answer 1

The correct option is A

convergent evolution

The correct option is A

The explanation for the correct option:

1. Convergent evolution is the process through which organisms that are not closely related gain comparable traits independently as a result of needing to adapt to similar environments or ecological niches. As a result, option A is right.
2. When distinct species independently develop similar features, this is known as convergence in evolution. Sharks and dolphins, for instance, resemble each other somewhat while being completely unrelated.

Explanation for incorrect options:

Option B

1. Non-random evolution occurs as a result of mating that did not happen by chance and, as a result, has been influenced by humans. As a result, option B is incorrect.

Option C

1. Adaptive radiation is a process in evolutionary biology in which organisms rapidly diversify into a variety of new forms, especially when a change in the environment makes new resources available, provides new obstacles, and opens new environmental niches. As a result, option C is incorrect.

Option D

1. The natural process by which creatures that are more adapted to their environment tend to survive, according to Darwin's theory of evolution. Thus, option D is wrong.

Final answer: The process by which organisms with different evolutionary histories evolve similar phenotypic adaptations in response to a common environmental challenge is called convergent evolution.
