Select the correct group/set of Australian Marsupials exhibiting adaptive radiation.

  1. Numbat, Spotted cuscus, Flying phalanger
  2. Mole, Flying squirrel, Tasmanian tiger cat
  3. Lemur, Anteater, Wolf
  4. Tasmanian wolf, Bobcat, Marsupial mole

Answer

(1) Numbat, Spotted cuscus, Flying phalanger

Solution

Australian marsupials such as the numbat (anteater), spotted cuscus, flying phalanger, Tasmanian wolf, Tasmanian tiger cat, marsupial mole, koala and kangaroo evolved from a common ancestral stock — an example of adaptive radiation.

Mole, flying squirrel, lemur, anteater, wolf and bobcat are placental mammals.

So only option (1) has all three Australian marsupials.
