Which of the following is shown by wings of bat and mosquito?

Options

A. divergent evolution
B. convergent evolution
C. speciation
D. homology in organs

Answer

To solve the question regarding the wings of bats and mosquitoes, we need to analyze the characteristics of these structures and the evolutionary concepts associated with them.

### Step-by-Step Solution:

1. **Understanding the Structures**:
- The wings of bats and mosquitoes are both used for flying, but they are structurally different. Bats have wings that are made of skin stretched over elongated finger bones, while mosquito wings are thin and membranous.

**Hint**: Look at the structural differences and similarities in function to classify the wings.

2. **Defining Homologous and Analogous Structures**:
- **Homologous Structures**: These are organs that have a similar anatomical structure due to shared ancestry, even if their functions differ. For example, the forelimbs of mammals (like humans, whales, and bats) are homologous.
- **Analogous Structures**: These are organs that perform similar functions but do not share a common ancestry. They arise due to convergent evolution. For example, the wings of bats and insects (like mosquitoes) are analogous.

**Hint**: Remember that homologous structures come from a common ancestor, while analogous structures do not.

3. **Identifying the Evolutionary Process**:
- The wings of bats and mosquitoes are examples of **convergent evolution** because they have evolved independently to perform the same function (flight) despite their different structural origins.

**Hint**: Think about how similar functions can evolve in unrelated species due to similar environmental pressures.

4. **Eliminating Incorrect Options**:
- **Divergent Evolution**: This does not apply here as it refers to homologous structures.
- **Speciation**: This refers to the formation of new species, which is not relevant to the question.
- Therefore, the only correct choice is **Convergent Evolution**.

**Hint**: Cross out the options that do not fit the definitions of homologous or analogous structures.

5. **Final Answer**:
- The correct answer is **Convergent Evolution**.

### Summary:
The wings of bats and mosquitoes are analogous structures that arose due to convergent evolution, as they serve the same function (flight) but have different anatomical structures and origins.
