Concept explainers
Introduction:
Sometimes unrelated species evolve similar traits even though they live in different parts of the world. This occurs in environments which are geographically far apart but that have similar ecology and climate.
Answer to Problem 27A
Correct answer :
The correct answer is option (C) convergent evolution.
Explanation of Solution
Explanation/justification for the correct answer :
Option (C) convergent evolution. The evolution of similar traits in unrelated species though they live in different parts of the world is called convergent evolution. As two unrelated plants shown in the illustration. Thus, this is the correct answer.
The explanation for the incorrect answer :
Option (A) adaptive radiation. When one species gives rise to many species in response to the creation of new habitat or another ecological opportunity is the adaptive radiation. Thus, this is an incorrect option.
Option (B) disruptive selection. It is a type of natural selection process in which a population is splits into two groups. Thus, this is an incorrect answer.
Option (D) Punctuated equilibrium. The punctuated equilibrium and gradualism are two models that explain the tempo of evolution. Thus, this is an incorrect answer.
