Age of fishes is

Options

A. Ordovician period
B. Permian period
C. Devonian period
D. None of these

Answer

To determine the age of fishes, we need to analyze the geological periods in which significant developments in fish evolution occurred. Here’s a step-by-step breakdown:

### Step 1: Understand the Geological Time Scale
The geological time scale is divided into various eras and periods. The Paleozoic era, known as the era of ancient life, is particularly important for the evolution of fishes.

### Step 2: Identify the Relevant Periods
Within the Paleozoic era, there are six key periods:
1. Cambrian
2. Ordovician
3. Silurian
4. Devonian
5. Carboniferous
6. Permian

### Step 3: Examine Each Period for Fish Evolution
- **Ordovician Period**: This period marks the first appearance of vertebrates, which include early fish.
- **Silurian Period**: This period is notable for the origin of jawed fishes.
- **Devonian Period**: Often referred to as the "Age of Fishes," this period is characterized by the dominance and diversification of fishes, including the emergence of amphibians.

### Step 4: Determine the Correct Answer
Given that the Devonian period is specifically known for the dominance of fishes, it is clear that this is the period that best represents the age of fishes.

### Conclusion
The age of fishes is primarily associated with the **Devonian period**.
