| (C) Lagomorpha | (III) Rhinoceroses |
| (D) Rodentia | (IV) Hares |
Choose the correct answer from the options given below:
1. (A) – (II), (B) – (III), (C) – (I), (D) – (IV)
2. (A) – (III), (B) – (IV), (C) – (II), (D) – (I)
3. (A) – (II), (B) – (I), (C) – (IV), (D) – (III)
4. (A) – (III), (B) – (II), (C) – (IV), (D) – (I)
Mammalian Orders Matching MCQ: Perissodactyla, Primates, Lagomorpha, Rodentia
Mammalian classification into orders helps identify evolutionary traits and examples. Questions matching orders like Perissodactyla to specific animals test taxonomy knowledge crucial for exams. This guide solves the exact MCQ with clear rationale.
Correct Answer: Option 4 – (A)–(III), (B)–(II), (C)–(IV), (D)–(I)
This option correctly pairs each order with its representative example based on standard mammalian taxonomy.
-
Perissodactyla (A) – Rhinoceroses (III): Odd-toed ungulates including rhinos, horses, tapirs; characterized by hooves with odd number of toes.
-
Primates (B) – Lemurs (II): Prosimians like lemurs belong to this order with forward-facing eyes and grasping hands.
-
Lagomorpha (C) – Hares (IV): Rabbits, hares, pikas; known for dual incisors and herbivory, distinct from rodents.
-
Rodentia (D) – Porcupines (I): Largest order; gnawing mammals like rats, squirrels, porcupines with chisel-like incisors.
Mammalian Orders Quick Reference Table
| Order | Key Traits | Examples |
|---|---|---|
| Perissodactyla | Odd-toed hooves, herbivores | Rhinoceroses, horses, zebras |
| Primates | Binocular vision, opposable thumbs | Lemurs, monkeys, apes |
| Lagomorpha | Two pairs of incisors, leaping | Hares, rabbits, pikas |
| Rodentia | Single pair upper incisors for gnawing | Porcupines, beavers, mice |
Why Other Options Are Incorrect
Option 1: (A)–(II), (B)–(III), (C)–(I), (D)–(IV)
Wrong. Perissodactyla aren’t lemurs (primates); primates aren’t rhinos; Lagomorpha exclude porcupines (rodents).
Option 2: (A)–(III), (B)–(IV), (C)–(II), (D)–(I)
Wrong. Primates exclude hares (Lagomorpha); Lagomorpha aren’t lemurs.
Option 3: (A)–(II), (B)–(I), (C)–(IV), (D)–(III)
Wrong. Perissodactyla not lemurs; primates not porcupines; Rodentia not rhinos.
These mix unrelated groups, testing precise recall of order definitions.
Exam Tips for Mammalian Orders Questions
-
Focus traits: Toe count (Perissodactyla), incisors (Lagomorpha vs Rodentia), brain complexity (Primates).
-
Mnemonics: “Peri-odd Rhinos; Prima-Lemurs; Laga-Hares; Rodent-Porcupines.”
-
Practice: Link to biodiversity, evolution chapters in NEET syllabus.
