Marsupials are found in:

Why did Australian marsupials survive after continental drift?

Describe various biogeographical evidences.

$A$: 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.

Marsupials and Australian placental mammals exhibit convergent evolution. Explain how?

In which biome can new plant species adapt most rapidly?
