Which one is palaeontological evidence of evolution?

Options

A. Biston betularia
B. Archaeopteryx
C. Darwin's finches
D. Duck billed platypus

Answer

To determine which option represents paleontological evidence of evolution, we can analyze each of the provided choices:

1. **Bison Betuliria**: This is a species of bison, which is a modern organism and does not serve as a direct evidence of evolutionary transitions.

2. **RQT Bricks**: This option represents a transitional fossil. Transitional fossils are crucial in paleontology as they provide evidence of the evolutionary links between different groups of organisms. RQT Bricks shows characteristics that connect non-avian feathered dinosaurs to modern birds, making it a significant piece of evidence in understanding the evolution of birds.

3. **Darwin's Finches**: While these finches are an important example of adaptive radiation and natural selection, they are not paleontological evidence. They are contemporary species that illustrate evolution in action but do not represent fossil evidence.

4. **Dolly the Platypus**: Dolly was a cloned sheep and does not pertain to paleontological evidence. The platypus itself is a modern organism and does not provide fossil evidence of evolution.

Based on this analysis, the correct answer is **RQT Bricks**, as it serves as a transitional fossil that provides paleontological evidence of evolution.

### Step-by-Step Solution:
1. **Identify the options**: Review the given options to understand what they represent.
2. **Analyze each option**: Determine if each option is a modern organism or a fossil that provides evidence of evolutionary transitions.
3. **Determine transitional fossils**: Identify which option shows characteristics that link different groups of organisms in the evolutionary timeline.
4. **Select the correct answer**: Conclude that RQT Bricks is the only option that serves as paleontological evidence of evolution.
