Natural Selection is a fundamental mechanism of evolution, where organisms with traits beneficial for their environment are more likely to survive and reproduce, thereby passing on these traits to subsequent generations. It is driven by factors such as variation in genetic inheritance, overproduction of offspring, and environmental pressures like predation or competition for resources. This process results in populations becoming better adapted to their surroundings over time, ultimately shaping the diversity of life on Earth. Natural Selection, therefore, encapsulates the interplay between Genetics and Evolution within the broader context of Science, providing a unifying framework for understanding how life has changed through time.
