Anatomically and structually different, but function similar structures are called

Options

A. Analogous
B. Divergent
C. Homologous
D. Convergent

Answer

To solve the question "Anatomically and structurally different, but function similar structures are called," we can follow these steps:

### Step 1: Understand the Terminology
We need to clarify the terms used in the question. The key phrases are "anatomically and structurally different" and "function similar." This indicates that we are looking for structures that serve the same purpose but have different anatomical features.

### Step 2: Analyze the Options
We have four options to consider:
1. **Analogous**
2. **Divergent**
3. **Homologous**
4. **Convergent**

### Step 3: Define Each Option
- **Analogous**: These are structures that perform similar functions but have different anatomical structures and origins. They arise in different species due to similar environmental pressures, leading to similar adaptations.

- **Divergent**: This refers to evolution from a common ancestor, resulting in homologous structures that may have different functions but share a similar anatomical structure.

- **Homologous**: These structures have a similar anatomical structure and origin but may serve different functions.

- **Convergent**: This is a process where different species evolve similar traits independently, often due to similar environmental challenges.

### Step 4: Identify the Correct Answer
Given the definitions, the term that best fits "anatomically and structurally different, but function similar structures" is **analogous**. This is because analogous structures are those that have evolved to perform similar functions despite having different anatomical structures.

### Conclusion
Thus, the correct answer to the question is **analogous**.
