When two similar species live in the same area, they may evolve to become more different in order to

Options

A. drive the other species to extinction
B. reduce competition
C. use up the other species resources
D. reduce genetic variation

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks why two similar species living in the same area may evolve to become more different from one another.

2. **Concept of Evolution**: Evolution refers to the gradual changes that occur in species over time. These changes can be driven by various factors, including competition for resources.

3. **Identifying Similar Species**: When two species are similar, they often require similar resources (food, habitat, etc.) to survive. This similarity can lead to competition between the two species.

4. **Competition and Its Effects**: When two species compete for the same resources, it can lead to a struggle where both species may be harmed. This is because their efficiency in utilizing those resources may decrease due to the competition.

5. **Competitive Exclusion Principle**: According to this principle, if two similar species are present in the same habitat and require similar resources, one species will eventually outcompete the other. This means that one species will survive while the other may be eliminated.

6. **Evolutionary Response**: To avoid being eliminated due to intense competition, the competitively inferior species may undergo evolutionary changes. These changes can help them utilize different resources or adapt to different niches, thereby reducing direct competition with the other species.

7. **Conclusion**: The reason why two similar species evolve to become more different is to reduce competition for resources, allowing both species to coexist rather than one being eliminated. Therefore, the correct answer is that such changes occur to lessen competition.

**Final Answer**: They may evolve to become more different in order to reduce competition for resources.
