Multiple Choice

• homologous structures.

• vestigial structures.

• homeotic structures.

• heterologous structures.

Answer 1

The wings of bat and a bird are example of Analogous structure.

Now,

Analogous structure:-- Those structure having similar function but they are different on structural basis.

Now ,

What causes Analogies ?

You know Convergent evolution is such evolution where evolution of similar features in species of different lineages.

Now ,

Note:-- Here, bat's wing are analogy to bird's wings but come to the Forelimbs which are homologous structure.
