Select the correct group/set of Australian Marsupials exhibiting adaptive radiation.
Explanation:
Option 3 is correct. In Australia, marsupials radiated into many forms to fill different ecological niches. Numbat (insectivore), Spotted cuscus (arboreal herbivore), and Flying phalanger (gliding omnivore) show diverse lifestyles, illustrating adaptive radiation within a single lineage in a shared environment.
🧠 Did You Know?
Australian marsupials evolved after Australia separated from other landmasses, leading to unique adaptations not seen in placental mammals of other continents.
💡 NCERT Memory Line:
