Select the pair which does not match.

Options

A. `{:("Coacervates",-,"Aggregates of organic compounds separated by an organic membrane"):}`
B. `{:("Lamrarck",-,"Species are not immutable"):}`
C. `{:("Allopatric speciation",-,"Separated by space"):}`
D. `{:("Darwin's finches",-,"Unique to Galapagos"):}`

Explanation

To solve the question of selecting the pair that does not match, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Coacervates**:
- Coacervates are structures that are believed to have existed on primitive Earth during the origin of life. They are aggregates of organic compounds, but they do not have a well-defined cellular structure.
- They are formed from colloidal solutions of organic molecules, such as proteins and lipids.

2. **Analyzing the Description of Coacervates**:
- The description states that coacervates are "aggregates of organic compounds separated by an organic membrane."
- This statement is incorrect because coacervates are not separated by an organic membrane; instead, they are separated from their surroundings by water molecules that form a barrier.

3. **Evaluating Other Options**:
- **Lamarck's View**: The statement that Lamarck said species are not immutable is correct. He believed in the evolution of species and that they could change over time.
- **Allopatric Speciation**: The definition stating that allopatric speciation involves groups separated by space (geographical barriers) is also correct. This leads to reproductive isolation and the formation of new species.
- **Darwin's Finches**: The statement about Darwin's finches being unique to the Galapagos Islands is accurate. These birds played a significant role in Darwin's development of the theory of evolution.

4. **Identifying the Incorrect Pair**:
- Based on the analysis, the incorrect combination is the one related to coacervates. They are not separated by an organic membrane, making this option the one that does not match.

### Final Answer:
The pair that does not match is the one describing coacervates as "aggregates of organic compounds separated by an organic membrane."
