Answer 2

Answer:

It was Alfred Wegener who proposed the idea of continental drift theory.

Explanation:

Biogeographical map of the world is that in which the six major biogeographic realms are present. Geologists believe that many million years ago, all the continents we demarcate today, were in the form of a single land mass called pangea. On account of geological changes, especially movements of crustal plates below the surface of the earth, huge land masses broke off and drifted apart from one another. As these land masses (continents) moved away, the seas separated them and acted as barriers to the free movement of organisms among the continents. Over centuries, plants and animals evolved independently in each biogeographical region.
