(D) Adaptive radiation is the process of evolution of different species in a given geographical area starting from a point and literally radiating to other areas of geography (habitats).$1.$ Darwin's finches of the Galapagos Islands are a classic example where a single ancestral species evolved into various forms with different beak shapes to suit different diets.$2.$ Australian marsupials represent another classic example of adaptive radiation,where a number of marsupials,each different from the other,evolved from an ancestral stock within the Australian island continent.$3.$ While the limbs of mammals show homologous structures,the term 'adaptive radiation' is most classically associated with the diversification of Darwin's finches and Australian marsupials. Given the options provided,all listed examples are recognized in evolutionary biology as instances of adaptive radiation.

List-$I$	List-$II$
$(a)$ Anteater	$(i)$ Marsupial mouse
$(b)$ Mouse	$(ii)$ Spotted cuscus
$(c)$ Mole	$(iii)$ Marsupial mole
$(d)$ Lemur	$(iv)$ Numbat

The classical example of adaptive radiation in the development of new species is:

$A$: Placental wolf and Tasmanian wolf (a marsupial) show convergent evolution.
$R$: Like marsupials,placental mammals in other parts of the world also exhibit adaptive radiation in evolving into varieties of such placental mammals,each of which appears to be similar to a corresponding marsupial.
