MHT CET · BIOLOGY · STD 12 - 5. Origin and Evolution of Life
Given below are two statements regarding evolution.
Statement-I: Isolation is the separation of population of a particular species into smaller units which prevents interbreeding between them.
Statement-II: Due to isolating mechanisms, divergence and speciation do not occur.
In the light of above statements, choose the most appropriate answer from the options give below
- A Both Statement-I and Statement-II are correct.
- B Statement-I is correct but Statement-II is incorrect
- C Both Statement-1 and Statement-II are incorrect.
- D Statement-I is incorrect but Statement-II is correct
Answer & Solution
Correct Answer
(B) Statement-I is correct but Statement-II is incorrect
Step-by-step Solution
Detailed explanation
Isolating mechanisms, which contribute to isolation between populations, are actually key factors that lead to divergence and speciation. Isolation allows for genetic differentiation and the accumulation of genetic changes over time, ultimately leading to the formation of new species.
