The correct Answer is:
To solve the question regarding how different varieties of pigeons, cattle, and crops have been developed, we will analyze each option provided. ### Step-by-Step Solution: 1. **Understanding the Question**: The question asks about the method through which different varieties of pigeons, cattle, and crops have been developed. 2. **Analyzing Option A - Artificial Selection**: - Artificial selection, also known as selective breeding, involves humans selecting specific organisms with desirable traits to breed. This process leads to the development of new varieties. - Example: Breeding pigeons for specific colors or patterns, or cattle for increased milk production. 3. **Analyzing Option B - Introductions**: - This term generally refers to the introduction of new genes or species into a population. While it can lead to variation, it does not specifically result in the development of new varieties in the same way as selective breeding does. - Therefore, this option is not the correct answer. 4. **Analyzing Option C - Evolution**: - Evolution is a natural process that occurs over long periods and involves changes in species due to environmental pressures and natural selection. It does not directly lead to the rapid development of new varieties of domesticated animals or crops. - Hence, this option is also incorrect. 5. **Analyzing Option D - Random Breeding**: - Random breeding refers to natural mating without human intervention. This method does not specifically target desirable traits and is less effective in producing distinct varieties compared to artificial selection. - Thus, this option is not correct either. 6. **Conclusion**: After analyzing all the options, it is clear that the correct answer is (a) Artificial selection, as it is the method through which different varieties of pigeons, cattle, and crops have been developed. ### Final Answer: (a) Artificial selection
