1. Variation: Individuals within a species display variations in their physical or behavioral traits. These variations can be inherited from parents or caused by random mutations.
2. Selection: Environmental factors such as predation, competition, disease, and availability of resources may limit the survival and reproduction of individuals with certain traits. Those with more favorable traits are more likely to survive and reproduce, passing on their advantageous traits to the next generation.
3. Reproduction: Individuals with advantageous traits are more likely to pass on those traits to their offspring, who will inherit those traits and have a better chance of survival and reproduction.
4. Adaptation: Over time, the advantageous traits become more common in the population, leading to adaptation to the environment. The species becomes better suited to survive and reproduce in that environment.
5. Speciation: Over longer periods, accumulation of advantageous traits may cause populations to become so different that they can no longer interbreed, leading to the formation of new species.
