The homologous organs are those that show similarity in

1. size

2. origin

3. function

4. appearance 

Forelimbs of cat, lizard used in walking; forelimbs of whale used in swimming and forelimbs of bats used in flying are an example of:

1. Analogous organs

2. Adaptive radiation

3. Homologous organs

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

Which of the following is an example of homologous organs?

1. Wings of butterfly and of birds

2. Eye of the Octopus and of mammals

3. Sweet potato and potato

4. Thorns of Bougainvillea and tendrils of Cucurbita

Structures given in the figure below represent the example of

1. Adaptive convergence

2. Convergent evolution

3. Analogy

4. Divergent evolution

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?

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

Distantly related organisms with similar traits have experienced:

1. Coevolution
2. Convergent evolution
3. Divergent evolution
4. Parallel evolution

Which of the following is not a result of convergent evolution?

1.  Potato and sweet potato

2.  Flippers of penguins and dolphins

3.  Eye of octopus and a mammal

4.  Thorn and tendril of Bougainvillea
