Vedclass · Answer

(A) Adaptive radiation refers to the process of evolution of different species in a given geographical area starting from a point and radiating to other areas of geography (habitats).When more than one adaptive radiation appears to have occurred in an isolated geographical area (representing different habitats),one can call this convergent evolution.Placental mammals in Australia also exhibit adaptive radiation in evolving into varieties of such placental mammals,each of which appears to be similar to a corresponding marsupial (e.g.,Placental wolf and Tasmanian wolf).Thus,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the Assertion.

$A$: 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.
