Evolution due to genetic changes within a species is

Options

A. Microevolution
B. Macroevolution
C. Megaevolution
D. Coevolution

Answer

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

1. **Understanding the Question:**
The question asks about the type of evolution that occurs due to genetic changes within a species.

2. **Identifying the Options:**
The options provided are:
- Microevolution
- Macroevolution
- Mega evolution
- Coevolution

3. **Defining Microevolution:**
Microevolution refers to small-scale evolutionary changes that occur within a species. This includes genetic changes at the molecular level, such as mutations in DNA sequences.

4. **Defining Macroevolution:**
Macroevolution involves larger-scale evolutionary changes that can lead to the formation of new species or groups of species. It encompasses significant evolutionary changes over long periods.

5. **Evaluating Mega Evolution:**
The term "mega evolution" is not a recognized concept in evolutionary biology, so this option can be disregarded.

6. **Defining Coevolution:**
Coevolution refers to the mutual evolutionary influence between two or more species. An example is the relationship between bees and flowers, where changes in one species can lead to changes in the other.

7. **Conclusion:**
Since the question specifically asks about evolution due to genetic changes within a single species, the correct answer is **microevolution**.

**Final Answer: Microevolution**
