Study of only one or a few organisms for obtaining knowledge about species/higher group is

Options

A. Nominalistic concept
B. Classical systematics
C. Typological concept
D. New systematics

Answer

To solve the question "Study of only one or a few organisms for obtaining knowledge about species/higher group is", we need to analyze the provided options and determine which one accurately describes this concept.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the term that describes the study of one or a few organisms to gain knowledge about a species or a higher taxonomic group.

2. **Analyze the Options**:
- **Option 1: Nominalistic Concept**: This concept suggests that species are merely a human creation and do not have real existence. This option does not fit the definition provided in the question.

- **Option 2: Classical Systematics**: This approach focuses on the morphological characteristics of organisms and does not account for changes in species over time. It does not emphasize studying only a few organisms for broader understanding.

- **Option 3: Typological Concept**: This concept posits that a few characters are sufficient to gain knowledge about a species or a higher group. It aligns well with the question since it emphasizes studying one or a few organisms.

- **Option 4: New Systematics**: This approach is more comprehensive and considers various characters, including genetic information, for classification. It does not focus on just one or a few organisms.

3. **Identify the Correct Option**: Based on the analysis, the Typological Concept (Option 3) is the correct answer because it specifically states that studying a few characters from one or a few organisms can provide sufficient knowledge about a species or a higher group.

### Conclusion:
The correct answer is **Option 3: Typological Concept**.
