Every year new species have been dicovered. In the nature, the discovery of new species is possible from :-

Options

A. New areas
B. Already explored areas
C. Both new and already explored areas
D. In vitro (laboratory) conditions only

Answer

To solve the question regarding the discovery of new species in nature, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks about the sources from which new species can be discovered in nature.

2. **Examine the Options**: The options provided typically include different environments or conditions where species might be found. In this case, we need to determine if new species can be discovered from new areas, already explored areas, or specific laboratory conditions.

3. **Consider the Scientific Perspective**: According to scientists like Robert May, there are millions of species yet to be discovered. He noted that only about 20% of species have been identified, suggesting that there are many more species in both new and previously explored areas.

4. **Evaluate Each Option**:
- **Option A**: New areas - This is a valid source for discovering new species, as unexplored regions may harbor unknown organisms.
- **Option B**: Already explored areas - This is also valid because new species can emerge or be identified in areas that have been previously studied.
- **Option C**: Both new and already explored areas - This option combines the two valid points above and is therefore correct.
- **Option D**: In vitro laboratory conditions only - This option is incorrect because while laboratory conditions can help in studying species, they are not the only means of discovering new species.

5. **Select the Correct Answer**: Based on the evaluation, the correct answer is **Option C**, which states that the discovery of new species is possible from both new areas and already explored areas.

### Final Answer:
The discovery of new species in nature is possible from **new areas or already explored areas (Option C)**.
