he island of Madagascar is located just off the SE coast of Africa, in the Indian Ocean. Scientists find species on this island that have close biological relatives in both Australia and India. They also find that at each location there are fossils of similar organisms. What is the most likely explanation for this similarity between organisms in Madagascar, India, and Australia?

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.
