New unit of evolution is called:

Options

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

Answer

**Step-by-Step Text Solution:**

1. **Understanding Evolution:**
- Evolution refers to the change in the heritable characteristics of biological populations over successive generations.

2. **Defining the Unit of Evolution:**
- The smallest unit of evolution is a population. A population is defined as a group of individuals of the same species that live in a specific geographical area and have the potential to interbreed.

3. **Characteristics of a Population:**
- A population consists of individuals that:
- Belong to the same species.
- Are geographically localized, meaning they inhabit the same area.
- Are present at the same time, allowing for interbreeding.
- Share a common gene pool, which is the total collection of genes and their variants in the population.

4. **Role of Population in Evolution:**
- Since a population can undergo changes in allele frequencies over time due to factors like natural selection, genetic drift, and mutations, it is considered the smallest unit that can evolve.

5. **Conclusion:**
- Therefore, the new unit of evolution is identified as a population.

**Final Answer:**
- The new unit of evolution is called a population.
