Question

Match List I with List II :

List - I		List – II
A.	Living Fossil	i.	Elongated canine teeth
B.	Connecting Link	ii.	Vermiform appendix
C.	Vestigial Organ	iii.	Echidna
D.	Atavism	iv.	Latimeria

Choose the correct answer from the options given below :

• A. A-IV, B-Ill, C-II, D-I
• B. A-IV, B-II, C-III, D-I
• C. A-IV, B-III, C-I, D-II
• D. A-III, B-IV, C-I, D-II

Answer 1

The Correct Option is A

To solve this question, we need to match terms from biology in List I with their corresponding definitions or examples in List II. Let's examine each term:

1. Living Fossil: This term refers to a living species that closely resembles species known only from fossils, with no close living relatives. The example of a living fossil is Latimeria, a genus of coelacanth fish that has shown little evolutionary change over millions of years. Hence, A matches iv.
2. Connecting Link: This refers to an organism that exhibits characteristics common to two different groups, marking an evolutionary connection between them. An example of a connecting link is the Echidna, which has features of both mammals and reptiles (egg-laying). Thus, B matches iii.
3. Vestigial Organ: These are body parts that have lost their original function through evolution. The Vermiform appendix in humans is an example of a vestigial organ, as it no longer aids in digestion. Therefore, C matches ii.
4. Atavism: This phenomenon involves the reappearance of traits of distant ancestors that had disappeared generations earlier. An example could be the appearance of elongated canine teeth in humans. Thus, D matches i.

Based on this analysis, the correct matching of List I with List II is A-IV, B-III, C-II, D-I.
