Question:
The evolution of eyes in octopus and in human is an example of ..............
The evolution of eyes in octopus and in human is an example of ..............
Show Hint
Convergent evolution occurs when species from different evolutionary lines develop similar traits due to similar environmental pressures or needs.
Updated On: Dec 11, 2025
- divergent evolution
- convergent evolution
- adaptive radiation
- genetic drift
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding evolution.
Convergent evolution occurs when different species independently evolve similar traits or features, often due to similar environmental pressures or needs. In this case, octopus and humans have evolved eyes that function in similar ways despite having very different evolutionary paths.
Step 2: Analyzing the options.
(A) divergent evolution: Incorrect — Divergent evolution refers to the process where two related species evolve different traits.
(B) convergent evolution: Correct — Both octopuses and humans have evolved eyes with similar functions, but from different evolutionary paths, making this an example of convergent evolution.
(C) adaptive radiation: Incorrect — Adaptive radiation refers to the rapid evolution of many species from a common ancestor, not the independent evolution of similar features.
(D) genetic drift: Incorrect — Genetic drift refers to random changes in gene frequencies in small populations, not the development of similar features.
Step 3: Conclusion.
The correct answer is (B) convergent evolution, as the eyes in octopuses and humans are an example of independent evolution of similar features.

The vector, shown in the figure, has promoter and RBS sequences in the 300 bp region between the restriction sites for enzymes X and Y. There are no other sites for X and Y in the vector. The promoter is directed towards the Y site. The insert containing only an ORF provides 3 fragments after digestion with both enzymes X and Y. The ORF is cloned in the correct orientation in the vector using the single restriction enzyme Y. The size of the largest fragment of the recombinant plasmid expressing the ORF upon digestion with enzyme X is ........... bp. (answer in integer)
