Adaptive radiation refers to

1. adaptations due to geographical isolation 

2. evolution of different species from a common ancestor

3. migration of members of a species to different geographical areas

4. power of adaptation in an individual to a variety of environments

When two species of different geneology come to resemble each other as a result of adaptation, the phenomenon is termed

1. divergent evolution

2. micro-evolution

3. co-evolution

4. convergent evolution

Which one of the following options gives one correct example each of convergent evolution and divergent evolution?

Parallelism is 

1. adaptive divergence

2. adaptive divergence of widely separated species

3. adaptive convergence of widely different species

4. adaptive convergence of closely related groups

Evolutionary convergence is the development of 

1. common set of characters in the group of different ancestry

2. dissimilar characters in closely related groups

3. common set of characters in closely related groups

4. random mating

The finches of Galapagos islands provide an evidence in favour of

1. special creation

2. evolution due to mutation

3. retrogressive evolution 

4. biogeographical evolution 

Convergent evolution is illustrated by

1. dogfish and whale

2. rat and dog

3. bacterium and protozoan

4. starfish and cuttle fish

The presence of the monotremes and marsupials in the Australian continent can be explained by:
