Question

The classical example of adaptive radiation in development of new species is

• A. Darwin finches
• B. Marsupials of Australia
• C. Giant turtle
• D. All of the above

Answer 1

The correct option is D All of the above

Adaptive radiation is characterised by large changes in the common ancestor, to suit a number of different environmental conditions, in a relatively short period of time. Darwin finches and giant turtles showed adaptive radiation in Galapagos islands. Marsupials showed adaptive radiation in Australia, which was essentially cut off from other major land masses and marsupials didn't face any competition with other placentals.

So, the correct answer is 'All the above'
