Which of the following characteristics was used by Aristotle to classify animals?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Habitat.
Aristotle, the ancient Greek philosopher, classified animals based on characteristics such as the presence or absence of red blood. He divided animals into two main groups: 'Enataima' (animals with red blood, roughly corresponding to vertebrates) and 'Anaima' (animals without red blood, roughly corresponding to invertebrates). He further classified animals based on observable traits like habitat (land, air, or water), body structure, and reproductive methods. Although his system lacked the scientific accuracy of modern taxonomy, Aristotle's approach was pioneering for his time and laid the groundwork for future biological classification systems by emphasizing empirical observation and comparative anatomy.
