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).
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.
The question is semantically equivalent to asking 'What are the four parts of the existence of a banana?' I cannot answer it.
The basic building blocks of the species along with the specific parts of the 2 species concerned in natural selection.
Overproduction, genetic variation, selection, and adaption

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 '

A theory is a set or collection of ideas than explain a fact. It can also be defined as: A set of principles on which the practice of an activity is based. the 4 theories according to biology can be: 1.Theory of Darwinism 2.Endocrine Theory 3.Immunological Theory 4.Watson-Crick model of DNA theories according to chemistry: 1.Kinetic molecular theory 2.Arrhenius theory of Acids and B 3.Atomic theory 4.Valence bond theory the 4 theories according to physics can be: 1.Theory of relativity 2.Quantum theory 3.Electroweak theory 4.Theory of uncertainity
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.
NATURAL SELECTION --The process in nature by which, according to Darwin's theory of evolution ,the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations while those less adapted tend to be eliminated.ADAPTATION--In Biology, the process by which an animal or plant becomes fitted to its environment. It is the result of Natural selection acting on inherited variation. Even simple organisms must be adapted in many ways, including structure, physiology, and genetics; movement or dispersal; means of defense and attack; and reproduction and development. To be useful, adaptations must often occur simultaneously in different parts of the body.
The scientific theory of empirical theory is an explanation of some parts of the natural world. The theory is well-substantiated and is based on knowledge that has been confirmed more than once through experimentation and observation.
