Choose the wrong pair

Options

A. Divergent evolution - Forelimbs of whales bats, cheetah and human
B. Convergent evolution - Flippers of penguins and dolphins
C. Homologous structures - Vertebrate hearts
D. Analogous structures-Tendrils of Bougainvillea and Cucurbita

Answer

To solve the question of identifying the wrong pair, we need to analyze each option based on the principles of evolution, specifically focusing on homologous and analogous structures.

### Step-by-Step Solution:

1. **Understanding Homologous Structures**:
- Homologous structures are those that have a similar origin (common ancestry) but may serve different functions. An example is the forelimbs of mammals like whales, cheetahs, and humans. Although they have different functions (swimming, running, and manipulating objects), their underlying structure is similar.

2. **Analyzing Option 1**:
- The first pair mentions "Diverse and Devolution" related to the forelimbs of whales, cheetahs, and humans. This is correct as it illustrates homologous structures, showing common ancestry.

3. **Understanding Convergent Evolution**:
- Convergent evolution occurs when organisms from different evolutionary backgrounds develop similar traits. An example is the flippers of penguins and dolphins, which serve the same function (swimming) but have different evolutionary origins.

4. **Analyzing Option 2**:
- The second pair refers to "Convergent evolution" with the flippers of penguins and dolphins. This is also correct as it illustrates analogous structures, which serve the same function but have different origins.

5. **Analyzing Option 3**:
- The third pair discusses "Homologous structures" in vertebrate hearts. This is correct because all vertebrate hearts share a common structure due to common ancestry.

6. **Analyzing Option 4**:
- The fourth pair mentions "analogous structure" with tendrils of bog and wheelia and cuckoo. This is incorrect. Tendrils of bog and wheelia and cuckoo are examples of homologous structures because they have a common ancestry, despite serving different functions.

7. **Conclusion**:
- The wrong pair is Option 4: "analogous structure, tendrils of bog and wheelia and cuckoo" because these structures are not analogous; they are homologous.

### Final Answer:
The wrong pair is **Option 4: Analogous structure, tendrils of bog and wheelia and cuckoo**.
