Find the odd one out related to evolution

Options

A. Vertebrate hearts
B. Vertebrate brains
C. Wings of butterfly and of birds
D. Forelimbs of mammals

Answer

To solve the question "Find the odd one out related to evolution," we will analyze each of the provided options in terms of their evolutionary relationships.

### Step-by-Step Solution:

1. **Identify the Options**:
- Option A: Vertebrate hearts
- Option B: Vertebrate brains
- Option C: Wings of butterfly
- Option D: Wings of birds
- Option E: Forelimbs of mammals

2. **Analyze Options A and B**:
- Both vertebrate hearts and vertebrate brains are found in vertebrates, which include a variety of animals (fishes, amphibians, reptiles, birds, and mammals).
- They exhibit homology, meaning they share a common evolutionary origin despite potentially differing in structure and function.

3. **Analyze Option E**:
- The forelimbs of mammals (like humans and bats) also show homology. They have a similar structural origin but serve different functions (e.g., flying in bats vs. manipulation in humans).

4. **Analyze Options C and D**:
- The wings of butterflies (insects) and birds (vertebrates) are an example of analogous structures. They serve the same function (flight) but have different evolutionary origins and anatomical structures.
- This means they do not share a common ancestry, which distinguishes them from the other options.

5. **Conclusion**:
- The odd one out is the **wings of butterfly** (Option C) because they are analogous to the wings of birds (Option D), while the other options (vertebrate hearts, vertebrate brains, and forelimbs of mammals) are homologous structures.

### Final Answer:
The odd one out is **wings of butterfly**.
