Natural selection is a key mechanism of evolution, first proposed by Charles Darwin in the 19th century. It describes the process by which certain heritable traits become more or less common in a population over successive generations, based on the reproductive success of individuals with those traits. Essentially, individuals with advantageous traits are more likely to survive and reproduce, passing those traits to their offspring. Core Principles of Natural Selection The process of natural selection operates on several core principles: - Variation: Individuals within a species exhibit differences in traits such as size, speed, coloration, or behavior. - Inheritance: Many traits are heritable and can be passed from parents to offspring. - Differential Survival and Reproduction: Some traits confer advantages that increase an individual's chances of survival and reproductive success. - Adaptive Advantage: Over time, advantageous traits become more common within the population, leading to adaptation.
