(N/A) An example of more than one adaptive radiation occurring in an isolated geographic area is the evolution of Australian marsupials and placental mammals.
In this case,a number of Australian marsupials,each different from the other,evolved from an ancestral stock,but all within the Australian island continent. Placental mammals in other parts of the world also exhibit adaptive radiation.
When more than one adaptive radiation appears to have occurred in an isolated geographical area,and two or more groups of unrelated animals come to resemble each other due to a similar mode of life or habitat,it is called $Convergent$ $Evolution$.
It is named $Convergent$ $Evolution$ because different evolutionary lineages 'converge' or come together to develop similar adaptive features to survive in similar environmental conditions.
