Which of the following statements is not true?
Which of the following statements is not true?
Updated On: Apr 14, 2025
- Analogous structures are a result of convergent evolution
- Sweet potato and potato is an example of analogy
- Homology indicates common ancestry
- Flippers of penguins and dolphins are a pair of homologous organs
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Flippers of penguins and dolphins have a similar function as both help in swimming. Their origin is different hence they are called analogous organs. Analogous structures are a result of convergent evolution in which different structures evolve for the same function and hence have similarity.

Evolution
Evolution is a process that occurs in changes in the genetic content of a population over time. Evolutionary change is generally classified into two: microevolution and macroevolution. The process of changes in allele frequencies in a population over time is a microevolutionary process. Three main mechanisms that cause allele frequency change are natural selection, genetic drift, and gene flow. On the other hand, macroevolution refers to change at or above the level of the species.
