Evolution of different species in a given area starting from a point and spreadig to other geographical areas is known as

Options

A. adaptive radiation
B. natural selection
C. migration
D. divergent evolution

Answer

To solve the question "Evolution of different species in a given area starting from a point and spreading to other geographical areas is known as," we will analyze the options provided and determine the correct answer step by step.

### Step-by-Step Solution:

1. **Understanding the Question**: The question is asking for a term that describes the evolution of different species originating from a specific point and then spreading to various geographical areas.

2. **Analyzing the Options**:
- **Option A: Adaptive Radiation**: This term refers to the process where organisms diversify rapidly from an ancestral species into a wide variety of forms to adapt to different environments. This fits the description of species evolving from a point and spreading into new areas with different traits.
- **Option B: Natural Selection**: This is a mechanism of evolution where organisms better adapted to their environment tend to survive and produce more offspring. While related to evolution, it does not specifically describe the spreading of species from a point.
- **Option C: Migration**: This term refers to the movement of organisms from one place to another. While it involves movement, it does not specifically address the evolutionary aspect of species adapting and evolving in new environments.
- **Option D: Divergent Evolution**: This refers to the process where two or more related species become more dissimilar over time, often due to different environmental pressures. It does not specifically describe the spreading of species from a point.

3. **Identifying the Correct Answer**: Based on the analysis, **Adaptive Radiation** (Option A) is the correct term that describes the evolution of different species starting from a point and spreading to other geographical areas.

### Final Answer:
The evolution of different species in a given area starting from a point and spreading to other geographical areas is known as **Adaptive Radiation**.
