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 genealogy come to resemble each other as a result of adaptation, the phenomenon is termed:
1. divergent evolution
2. microevolution
3. co-evolution
4. convergent evolution

An important evidence in favour of organic evolution is the occurrence of:

1. homologous and vestigial organs

2. analogous and vestigial organs

3. homologous organ only

4. analogous organ only

Variations caused by mutation, as proposed by Hugo de Vries, are:
