Final answer:
Competition among individuals is actually essential for natural selection, not the lack of it. The correct requirements for natural selection include variation within a population, inheritance of traits, and differential survival and reproduction.
Step-by-step explanation:
The answer to your question about the requirements for natural selection is that option d, 'Lack of competition among individuals,' is NOT a requirement for natural selection. Instead, competition for limited resources is one of the essential conditions that must be met for natural selection to occur. The other requirements include:
- Variation within a population.
- Inheritance of traits.
- Differential survival and reproduction.
Thus, variation, inheritance, and differential survival and reproduction are all critical components that drive the process of evolution through natural selection.
