An Australian mole is actually a marsupial rather than a placental animal like the North American or European mole. The two animals are similar in appearance because
1 The selection pressures on both were similar
2 They have undergone a long period of coevolution
3 There are practically no placental mammals in Australia
4 Marsupials and placental mammals are closely related
Explanation:
Australian mole resemble to that of the mole of Europe or North America. This is the result of convergent evolution, in which similar features develop separately in different species due to same selection pressures.

2 They all are example of adaptive radiation
3 They have evolved from a common ancestor

The development of various functional structures from a common ancestral form is called
1 Chemical evolution
2 Adaptive radiation
3 Non-adaptive radiation
4 Mutational evolution
Explanation:
Development of different functional structures from a common ancestral form is called adaptive radiation.

When more than one adaptive radiation appeared to have occurred in an isolated geographical area, it is
1 Convergent evolution
2 Divergent evolution
3 Natural selection
4 Genetic drift
Explanation:
Convergent evolution. Adaptive radiation refers to an evolutionary process in which different species evolve successfully to adapt to their environment on inhabiting new areas. While convergent evolution is an evolutionary process in which different structures of different species are evolved for the same function. Hence during adaptive radiation, the changes are determined by the environment. The organism evolves to survive in a particular environment. Therefore, if two different adaptive radiation occurs in an area, Then it is most likely that both the evolved species will have similar adaptations to survive in the particular area. Hence, they will develop similar structures to perform similar functions which show convergent evolution.
