Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
पद 1: प्रश्न को समझना
हमें unrelated species में समानता के evolutionary concept को पहचानना है।
पद 2: मुख्य सूत्र या दृष्टिकोण
जब unrelated organisms समान adaptations विकसित करते हैं, उसे convergent evolution कहते हैं।
पद 3: विस्तृत व्याख्या
Placental mammals और Australian marsupials अलग ancestry रखते हुए भी similar ecological roles के कारण समान features दिखाते हैं।
पद 4: अंतिम उत्तर
अतः सही विकल्प (D) है।
