Concept Of Organic Evolution Evidence 2

Darwin's finches are a good example of:

1. industrial melanism

2. connecting link

3. adaptive radiation

4. convergent evolution

Evolution of different species in a given area starting from a point and spreading to other geographical areas is known as:

1.	Adaptive radiation	2.	Natural selection
3.	Migration	4.	Divergent evolution

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

	Convergent Evolution	Divergent Evolution
1.	Eyes of octopus and mammals	Bones of forelimbs of vertebrates
2.	Thorns of Bougainvillea and tendrils Cucurbita	Wings of butterflies and birds
3.	Bones of forelimbs of vertebrates	Wings of butterfly and birds
4.	Thorns of Bougainvillea and tendrils of Cucurbita	Eyes of Octopus and mammals

The process by which organisms with different evolutionary history evolve similar phenotypic adaptations in response to a common environmental challenge is called:
1. Convergent evolution
2. Non-random evolution
3. Adaptive radiation
4. Natural selection

The wings of a bird and the wings of an insect are:

1.	Homologous structures, represent divergent evolution
2.	Analogous structures, represent convergent evolution
3.	Phylogenetic structures, represent divergent evolution
4.	Homologous structures, represent convergent evolution

Among the following sets of examples for divergent evolution, select the incorrect option:

1. Forelimbs of man, bat and cheetah
2. Heart of bat, man and cheetah
3. Brain of bat, man and cheetah
4. Eye of octopus, bat and man

The phenomenon of the evolution of different species in a given geographical area starting from a point and spreading to other habitats is called:

1.	Saltation	2.	Co-evolution
3.	Natural selection	4.	Adaptive radiation
