New unit of evolution is called:

Options

A. Population
B. Genus
C. Order
D. Species

Answer

To solve the question "New unit of evolution is called:", we will analyze the options provided and determine which one represents the new unit of evolution.

### Step-by-Step Solution:

1. **Understanding Evolution**:
- Evolution is defined as the gradual change that occurs in living organisms over time. It involves changes in the genetic makeup of populations.

2. **Identifying the Options**:
- The options given are:
- A) Population
- B) Genus
- C) Order
- D) Species

3. **Analyzing Each Option**:
- **Population**:
- A population is a group of individuals of the same species that live in a specific area. It is the smallest unit where evolution can occur because evolutionary changes happen through changes in allele frequencies within a population over generations.
- **Genus**:
- A genus is a higher taxonomic rank that groups together species that are closely related. It is not considered a unit of evolution.
- **Order**:
- An order is a higher taxonomic category that encompasses multiple families. It is not relevant as a unit of evolution.
- **Species**:
- A species is a group of individuals that can interbreed and produce fertile offspring. While it is a significant unit in taxonomy, it is not the smallest unit where evolution occurs.

4. **Conclusion**:
- Based on the analysis, the correct answer is **A) Population**. This is because evolution occurs at the population level, where genetic variations and changes can be observed.

### Final Answer:
The new unit of evolution is called **Population**.
