The ancestor of these organisms lived on a landmass long ago that included Madagascar, India, and Australia.

Explanation:

The three, Madagascar, India and Australia were found together on a piece of land called Gondwana, which were part of the continent called Pangea, approximately 300 million years ago. Gondwana began its separation at the beginning of the Jurassic. Meanwhile, South America began to separate to the west. On the other hand, East Gondwana, which was made up of Antarctica, Madagascar, India and Australia, began its separation from Africa.
