Organs which differ in their origin and development but perform similar function are

Options

A. Vestigial organs
B. Homologous organs
C. Analogous organs
D. Atavistic organs

Answer

To solve the question "Organs which differ in their origin and development but perform similar function are:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Terms**:
- First, we need to understand the different types of organs mentioned in the options:
- **Vestigial organs**: These are organs that have lost most or all of their original function through the course of evolution.
- **Homologous organs**: These are organs that have a similar origin and structure but may serve different functions.
- **Analogous organs**: These are organs that have different origins and structures but perform similar functions.
- **Atavistic organs**: These are traits that reappear after being absent for generations.

2. **Identifying the Correct Type**:
- The question specifically asks for organs that differ in their origin and development but perform similar functions.
- Based on the definitions, we can eliminate vestigial and homologous organs since they do not fit the criteria of differing origins.

3. **Choosing the Right Answer**:
- The only type of organ that fits the description of differing in origin and development while performing similar functions is **analogous organs**.
- For example, the wings of birds and insects serve the same function (flight) but have different evolutionary origins.

4. **Final Answer**:
- Therefore, the correct answer to the question is **analogous organs**.
