For natural selection to occur, the following conditions are necessary:
1. **Variation**: Individuals within a population must have differences in traits (like size, color, or speed).
2. **Heritability**: Some of these traits must be passed down from parents to offspring.
3. **Overproduction**: More offspring are produced than can survive, leading to competition for resources.
4. **Differential Survival and Reproduction**: Individuals with traits that give them an advantage are more likely to survive and reproduce, passing those advantageous traits to the next generation.
These conditions lead to the gradual evolution of populations over time.
