Question

Match List-I with List-II:

List-I Placental mammals	List-II Counterpart Marsupials
(A) Anteater	(II) Numbat
(B) Bobcat	(IV) Tasmanian tiger cat
(C) Lemur	(I) Spotted cuscus
(D) Flying squirrel	(III) Flying Phalanger

Choose the correct answer from the options given below:

• (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
• (A) - (II), (B) - (I), (C) - (IV), (D) - (III)
• (A) - (IV), (B) - (I), (C) - (II), (D) - (III)
• (A) - (IV), (B) - (I), (C) - (III), (D) - (II)

Answer 1

The Correct Option is A

To solve the problem of matching List-I (Placental mammals) with List-II (Counterpart Marsupials), we need to identify the respective pairs. Here's how the matching works:

List-I Placental mammals	List-II Counterpart Marsupials
(A) Anteater	(II) Numbat
(B) Bobcat	(IV) Tasmanian tiger cat
(C) Lemur	(I) Spotted cuscus
(D) Flying squirrel	(III) Flying Phalanger

We will verify the correct answer by checking each pair one by one: 

1. Anteater is matched with the Numbat, a marsupial that also has a long tongue and eats termites, thus (A) - (II).
2. Bobcat is similar to the Tasmanian tiger cat in behavior and ecological niche, hence (B) - (IV).
3. Lemur is matched with the Spotted cuscus, both being arboreal and nocturnal, meaning (C) - (I).
4. Flying squirrel matches with the Flying Phalanger as both can glide, resulting in (D) - (III).

Therefore, the correct matching is: (A) - (II), (B) - (IV), (C) - (I), (D) - (III).

Answer 2

Correct Matches: Analogous Mammals 

This table represents the correct matches between animals exhibiting similar ecological roles and/or physical characteristics, despite being found in different geographic regions and often belonging to distinct evolutionary lineages. This phenomenon is an example of convergent evolution.

Mammal Analogies:

1. (A) Anteater - (II) Numbat

Explanation: Both anteaters and numbats feed primarily on ants and termites and have adaptations for this diet, such as long snouts and sticky tongues.

1. (B) Bobcat - (IV) Tasmanian Tiger Cat (Quoll)

Explanation: Bobcats (North America) and Quolls (Australia) are both medium-sized carnivorous marsupials that occupy similar predatory niches in their respective ecosystems.

1. (C) Lemur - (I) Spotted Cuscus

Explanation: Both lemurs and spotted cuscus are arboreal primates (lemurs are placental primates, while cuscus are marsupial). They both occupy similar niches as arboreal omnivores/frugivores.

1. (D) Flying Squirrel - (III) Flying Phalanger

Explanation: Both flying squirrels (placental mammals) and flying phalangers (marsupials) possess gliding membranes (patagia) that allow them to glide between trees. This is a classic example of convergent evolution.
