Solution


Q.

The similarity of bone structure in the forelimbs of many vertebrates is an example of                  [2018]
1 homology  
2 analogy  
3 convergent evolution  
4 adaptive radiation  

Ans.

(1)

Homologous organs are those organs which have the same fundamental structure but are different in functions. Wings of birds and forelimbs of horse show homology because skeletal parts of their forelimbs are similar in structure and arrangement but have different functions.
