Evolution is the sequence of gradual changes which takes place in the primitive organisms, over millions of years, in which new species are produced. Variations that resulted in formation of new species occurred basically due to errors in DNA copying as well as due to sexual reproduction.
Which of these organisms have compound eyes?

Options

A. Flatworm
B. Insect
C. Human
D. none of these

Answer

To determine which organism has compound eyes among the given options, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Compound Eyes**:
- Compound eyes are a type of eye structure found in certain animals, primarily insects. They consist of multiple small visual units called ommatidia.

2. **Analyze the Options**:
- The options provided are:
- A) Flatworm
- B) Insect
- C) Human
- D) None of these

3. **Identify Characteristics of Each Option**:
- **Flatworm**: Flatworms have simple eyespots that can detect light but do not have compound eyes.
- **Insect**: Most insects possess compound eyes, which are made up of numerous ommatidia, allowing them to have a wide field of vision and detect motion effectively.
- **Human**: Humans have camera-type eyes, which consist of a single lens and do not have compound eyes.
- **None of these**: This option would imply that none of the organisms listed have compound eyes.

4. **Determine the Correct Answer**:
- Based on the analysis, the organism that has compound eyes is **B) Insect**.

### Final Answer:
The organism that has compound eyes is **B) Insect**.
