Q. Which of the following set shows convergent evolution?
Solution:
The evolution of various types of placental mammals from an ancestral stock within the Australian island continent is an example of adaptive radiation. If more than one adaptive radiation occurs in the same region (adaptive radiation in marsupials and placental mammals in the same Australian continent) representing different habitats, similarities develop among the organisms of the same habitat. This can be termed as convergent evolution.
