Which of the following evidences does not favour the lamarckian concept of inheritance of acquired characters?

Options

A. Lack of pigment in cave dwellers
B. Absence of limbs in snakes
C. Presence of webbed toes in aquatic birds
D. Melanization of pepperd moth in industrial areas

Explanation

To determine which evidence does not support the Lamarckian concept of inheritance of acquired characters, we need to understand the key principles of Lamarckism and evaluate the options provided.

### Step-by-Step Solution:

1. **Understanding Lamarckism**:
- Lamarck proposed that organisms can acquire traits during their lifetime based on their needs and that these acquired traits can be passed on to their offspring. This is often summarized as "use and disuse" of organs.

2. **Evaluating the Options**:
- **Option 1: Lack of pigment in cave dwellers**: This supports Lamarckism because cave dwellers do not need pigmentation in the dark, suggesting that the lack of pigment is an acquired trait that could be inherited.
- **Option 2: Absence of limbs in snakes**: This also supports Lamarckism as snakes that live in burrows may not need limbs, leading to their disuse and eventual inheritance of this trait.
- **Option 3: Presence of webbed toes in aquatic birds**: This supports Lamarckism as well, as the need for swimming may lead to the development of webbed toes, which could be passed on.
- **Option 4: Melanization of the peppered moth in industrial areas**: This does not support Lamarckism. The change in coloration of the peppered moth is an example of natural selection, where the environment (industrial soot) favored darker moths, leading to their increased survival and reproduction. This is not an acquired trait but rather a genetic variation that was naturally selected.

3. **Conclusion**:
- The evidence that does not favor the Lamarckian concept of inheritance of acquired characters is **Option 4: Melanization of the peppered moth in industrial areas**.

### Final Answer:
**Option 4: Melanization of the peppered moth in industrial areas does not favor the Lamarckian concept of inheritance of acquired characters.**
