Overproduction, genetic variation, selection, and adaption
The process of natural selection has three main parts: variation, heredity, and differential reproductive success. These parts work together to drive evolutionary change in populations over time.
Natural selection is the changing of organisms gradually over time. Natural selection and evolution are parts of environmental science due to them being the studies of organisms.

Darwin's theory of natural selection proposes that individuals with advantageous traits are more likely to survive and reproduce, passing their traits on to the next generation. The key components of natural selection include variation in traits within a population, inheritance of traits from parents to offspring, and competition for limited resources leading to differential survival and reproduction based on those traits. Over time, this process can result in the evolution of a population as advantageous traits become more common.
The question is semantically equivalent to asking 'What are the four parts of the existence of a banana?' I cannot answer it.
Because he thought is was a nice explanation to the way plants and animals had gotten slightly different shapes to fit better into different parts of the environment.
Darwin's and Wallace's theory of evolution by natural selection includes five main parts: Variation: Individuals within a species exhibit variations in traits. Inheritance: Traits are passed down from parents to offspring. Overproduction: Organisms tend to produce more offspring than can survive. Struggle for Existence: Competition for limited resources leads to survival challenges. Natural Selection: Individuals with advantageous traits are more likely to survive and reproduce, leading to the gradual evolution of species over time.
The two papers of Charles Robert Darwin and Alfred Russel Wallace dealing with this subject were read to the Linnean Society on July 1, 1858. This was the first and most complete theory of evolution by natural selection that the world heard of, though there were minor differences between Darwin's and Wallace's theory. ( there were others who had parts of the theory correctly elucidated, but they were not complete in their presentations, or they only had passing acquaintance with this subject ) On November 22, 1859 Darwin published ' On The Origin Of Species By Means Of Natural Selection, Or The Preservation Of Favored Races In The Struggle For Life '
Charles Darwin developed the theory of evolution after observing the diversity of species during his travels on the HMS Beagle. He realized that species were not fixed and unchanging, but instead evolved over time through natural selection. Darwin's theory revolutionized biology and our understanding of the natural world.
Darwin's Theory of Evolution consists of three main parts: variation, inheritance, and selection. Variation refers to differences in traits among individuals, inheritance involves passing on these traits to offspring, and selection entails the process by which certain traits become more common in a population due to their advantage in survival and reproduction.
Charles Darwin may have popularized the term "natural selection" but the idea has been around for centuries. Even Aristotle had thoughts about whether different parts of the body occurred accidentally but only the useful parts survived. Darwin even mentions in his On the Origin of Species his high regards of zoologist Edward Blyth's ideas of variations in nature.
The theory of use and disuse, proposed by Jean-Baptiste Lamarck, suggests that organisms can develop new characteristics or lose existing ones based on how they use or fail to use certain parts of their bodies. According to this theory, traits that are used frequently become more pronounced, while those that are not used can diminish over time. This theory has been largely discredited in modern biology, with natural selection and genetic inheritance playing larger roles in shaping traits.
