Species occuring in different geographical area are called as

Options

A. Sympatric
B. Allopatric
C. Sibling
D. Neopatric

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the term used to describe species that are found in different geographical areas.

2. **Identifying Key Terms**: The key term here is "different geographical area." This indicates that we are looking for a type of speciation or classification of species based on geographical separation.

3. **Defining Allopatric Speciation**: Allopatric speciation occurs when populations of a species become geographically isolated from each other. This isolation prevents them from interbreeding, leading to genetic divergence over time.

4. **Explaining Genetic Interaction**: In allopatric conditions, there is no genetic interaction between the isolated populations. This means that they evolve independently due to different environmental pressures and mutations.

5. **Eliminating Incorrect Options**:
- **Sympatric**: Refers to species that are reproductively isolated but live in the same geographical area. This does not fit the question.
- **Sibling**: Typically refers to closely related species that may not be geographically isolated.
- **Neopatric**: This term is not commonly used in this context and does not apply here.

6. **Conclusion**: The correct term for species occurring in different geographical areas is **Allopatric**.

### Final Answer:
Species occurring in different geographical areas are called **Allopatric**.
