Flipper of whale, paw of a cat, foreleg of a horse, and hand of a human being are example for

Options

A. Vestigial organs
B. Homologous organs
C. Analogous organs
D. Over specialised organs

Answer

To determine the correct classification for the flipper of a whale, the paw of a cat, the foreleg of a horse, and the hand of a human being, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structures**:
- We have four structures: flipper of a whale, paw of a cat, foreleg of a horse, and hand of a human being.

2. **Analyze Their Functions**:
- The flipper of a whale is used for swimming.
- The paw of a cat is used for walking and hunting.
- The foreleg of a horse is used for running.
- The hand of a human is used for manipulation and grasping.

3. **Compare Their Morphology**:
- Despite their different functions, these structures have a similar underlying skeletal structure. For example, they all contain similar bone arrangements (humerus, radius, and ulna).

4. **Determine the Evolutionary Relationship**:
- These structures are derived from a common ancestor, which indicates that they have evolved from a similar origin but adapted to different environments and functions. This is known as divergent evolution.

5. **Classify the Structures**:
- Based on the analysis, these structures are classified as **homologous organs**. Homologous organs are those that share a common ancestry but may have different functions.

### Conclusion:
The correct answer is that the flipper of a whale, paw of a cat, foreleg of a horse, and hand of a human being are examples of **homologous organs**.
