If you're preparing for a unit test on natural selection, here are some key concepts, terms, and potential questions that may help you review the material.
### Key Concepts:
1. **Natural Selection**: A process where organisms better adapted to their environment tend to survive and produce more offspring. It is one of the key mechanisms of evolution.
2. **Variation**: Individuals in a population have different traits. Variation can be due to genetic differences.
3. **Inheritance**: Traits that are advantageous can be passed down to offspring.
4. **Differential Survival and Reproduction**: Not all individuals get to reproduce; those with traits better suited to the environment tend to leave more offspring.
5. **Adaptation**: Over time, natural selection can lead to populations adapting to their environments.
6. **Fitness**: The ability of an organism to survive and reproduce in its environment.
7. **Selection Pressure**: Environmental factors that favor certain traits over others.
### Potential Questions:
1. **What is natural selection, and how does it contribute to evolution?**
2. **Explain the concept of "survival of the fittest." What does "fitness" mean in this context?**
3. **Describe how variation within a population can affect natural selection. Provide an example.**
4. **What role does genetic inheritance play in natural selection?**
5. **How can environmental changes lead to different selection pressures? Give a specific example in your answer.**
6. **Differentiate between natural selection and artificial selection.**
7. **What is meant by the term "adaptive radiation"? Provide an example of this phenomenon.**
8. **What evidence supports the theory of natural selection? List at least three pieces of evidence.**
9. **How can natural selection lead to speciation?**
10. **Can natural selection act on non-heritable traits? Why or why not?**
### Studying Tips:
- **Review Key Terms**: Make sure you understand and can explain key terms associated with natural selection.
- **Use Examples**: Familiarize yourself with real-world examples of natural selection, such as the peppered moth, Darwin's finches, or antibiotic resistance in bacteria.
- **Discuss with Peers**: Engaging in discussions can help clarify concepts and make connections to real-life applications of natural selection.
- **Practice Diagrams**: Understand how to illustrate the process of natural selection through diagrams or flowcharts.
