Natural selection is the process by which individuals with advantageous traits are more likely to survive and reproduce in their environment. This process leads to the gradual evolution of populations over time, as favorable traits become more common. The variations in traits within a population are due to genetic and environmental factors. Individuals with traits that increase their fitness are more likely to pass on their genes to the next generation, resulting in the accumulation of favorable traits within the population. This process ultimately leads to the adaptation of populations to their specific environments, as organisms with traits that are well-suited to their surroundings have a higher chance of survival and passing on their genes.
