The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Context**: The question discusses the rapid emergence of resistant organisms or cells in response to the use of antibiotics or drugs. This phenomenon occurs over a short time scale (months or years) rather than the long time scale typically associated with evolution. 2. **Defining Key Terms**: - **Antibiotics/Drugs**: Substances used to kill or inhibit the growth of microorganisms or cells. - **Eukaryotic Organisms/Cells**: Organisms whose cells have a nucleus enclosed within membranes, including fungi, plants, and animals. - **Resistance**: The ability of an organism to withstand the effects of a drug that once could successfully treat it. 3. **Identifying the Mechanism**: The rapid development of resistance in organisms is primarily due to mutations. When exposed to antibiotics, some organisms may have genetic variations that allow them to survive. These survivors reproduce, leading to a population that is increasingly resistant to the drugs. 4. **Human Influence**: The term "anthropogenic action" refers to changes in the environment caused by human activities. The overuse and misuse of antibiotics and pesticides create selective pressure on organisms, leading to the rapid evolution of resistant strains. 5. **Examples of Anthropogenic Action**: - **Pests and Herbicides**: Pests that were once susceptible to herbicides develop resistance due to the selective pressure from repeated applications of these chemicals. - **Viruses**: The emergence of new variants of viruses (like coronavirus variants) in response to antiviral drugs exemplifies how human actions (such as medication use) can lead to rapid evolutionary changes. 6. **Conclusion**: The evolution of resistant organisms in response to antibiotics and drugs is an example of evolution driven by anthropogenic actions. This highlights how human activities can significantly accelerate the process of evolution in various organisms. **Final Answer**: These are examples of evolution due to anthropogenic action. ---
