Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Evolved from different ancestors, but due to living in similar environments have a similar function.
A
Homologous structures
B
Analogous structures
C
Vestigial structures
D
All of the above
Explanation: 

Detailed explanation-1: -This form of evolution is referred to as convergent evolution. Convergent evolution is a kind of evolution wherein organisms evolve structures that have similar (analogous) structures or functions in spite of their evolutionary ancestors being very dissimilar or unrelated.

Detailed explanation-2: -Analogous structures are features of different species that are similar in function but not necessarily in structure and which do not derive from a common ancestral feature (compare to homologous structures) and which evolved in response to a similar environmental challenge.

Detailed explanation-3: -Analogous structures are structures that are similar in unrelated organisms. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor. For example, the wings of bats and birds, shown in Figure below, look similar on the outside.

Detailed explanation-4: -Analogous structures are structures that are similar in unrelated organisms. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor.

Detailed explanation-5: -Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is homoplasy.
