Solution


Q.

Sweet potato and potato represent a certain type of evolution. Select the correct combination of terms to explain the evolution.         [2025]
1 Analogy, convergent  
2 Homology, divergent  
3 Homology, convergent  
4 Analogy, divergent  

Ans.

(1)

Sweet potato is a root modification while potato is a stem modification but both of them have same function. Analogous structures are not anatomically similar structures though they perform similar functions.

Analogous structures are the result of convergent evolution.

• Homologous organs are anatomically similar but they do not perform similar function. Homologous organs are the result of divergent evolution.
