1. Variation: Individuals within a population have different traits. These variations can be in physical characteristics, behaviors, or even things like resistance to diseases.
2. Inheritance: Some of these variations are heritable, meaning they can be passed down from parents to offspring.
3. Competition: Individuals compete for resources like food, shelter, mates, and territory. This competition can be with members of their own species or with other species.
4. Differential Survival and Reproduction: Individuals with traits that make them better suited to their environment are more likely to survive and reproduce, passing those traits on to their offspring.
5. Adaptation: Over time, the frequency of beneficial traits increases in the population, leading to adaptation—a process where a species becomes better suited to its environment.
Reproduction is a crucial part of the process because it allows for the transmission of beneficial traits from one generation to the next. It's not a separate step, but rather a necessary component for the entire process to occur.
