The three parts of Darwin's theory of evolution by natural selection are struggle for existence (competition), survival of the fittest (those with the best adaptations for the time/environment live and reproduce), and descent with modification (over time the population is more representative of organisms with the best adaptations).
The three patterns of natural selection are directional selection, stabilizing selection, and disruptive selection. Directional selection favors individuals at one extreme of a trait distribution, stabilizing selection favors the intermediate phenotype, and disruptive selection favors individuals at both extremes of a trait distribution.
Natural selection requires variation in traits within a population, heritability of those traits, and differential reproductive success based on those traits. Without these components, natural selection cannot act on a population.
Biodiversity emerges from genetic diversity within species, species diversity, and ecosystem diversity. These three components work together to create the variety of life forms and ecosystems on Earth.
genetic diversity more efficient natural selection
Evolution occurs via natural selection when certain traits become more favorable in a population over time. This is typically due to the environment or natural selection pressures in the population. Natural selection works by favoring individuals with traits that are better suited to the environment while those with less favorable traits may die off or be less likely to reproduce. Over time these favored traits become more common while unfavorable traits become less common. This process eventually leads to evolution as the population changes to adapt to its environment. The three main components of natural selection are: Variation: Individuals within a population have different traits Inheritance: Traits are passed from generation to generation Differential Reproduction: Traits that are more favorable are more likely to be passed onNatural selection is an ongoing process as the environment is constantly changing and influencing the traits of the population. It is important to note that natural selection is not a directed process and does not necessarily lead to a specific outcome. The result of natural selection is determined by the environment and the traits that are favored in the population.
Three basic components of today's theory of evolution are genetic variation within a population, natural selection acting on this variation, and the inheritance of traits that confer a survival or reproductive advantage.

Genetic drift, as it is a random process that does not necessarily contribute to the differential survival and reproduction of individuals. Variation, heritability, and differential reproductive success are essential components of natural selection.
