What statements best describes natural selection?

Natural selection is a process in which individuals with favorable traits are more likely to survive and reproduce, passing those traits to future generations. It leads to adaptations within a species over time, enhancing their ability to thrive in specific environments. This mechanism is a key driver of evolution, as it results in the gradual change of species in response to environmental pressures. Ultimately, natural selection shapes the diversity of life by favoring traits that improve fitness.
