What are the parts of Darwin’s theory?

Darwin's theory of evolution, also called Darwinism, can be further divided into 5 parts: "evolution as such", common descent, gradualism, population speciation, and natural selection. ... The modern understanding of the process of natural selection is discussed in further detail in Synthesis of Darwin and Genetics. The four key points of Darwin's Theory of Evolution are: individuals of a species are not identical; traits are passed from generation to generation; more offspring are born than can survive; and only the survivors of the competition for resources will reproduce. four components.
Variation. Organisms (within populations) exhibit individual variation in appearance and behavior. ...
Inheritance. Some traits are consistently passed on from parent to offspring. ...
High rate of population growth. ...
Differential survival and reproduction. The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. More explanation: Natural selection is an inevitable outcome of three principles: most characteristics are inherited, more offspring are produced than are able to survive, and offspring with more favorable characteristics will survive and have more offspring than those individuals with less favorable traits. Natural selection is a simple mechanism that causes populations of living things to change over time. In fact, it is so simple that it can be broken down into five basic steps, abbreviated here as VISTA: Variation, Inheritance, Selection, Time and Adaptation. Terms in this set (6)
five points. competition, adaption, variation, overproduction, speciation.
competition. demand by organisms for limited environmental resources, such as nutrients, living space, or light.
adaption. inherited characteristics that increase chance of survival.
variation. ...
overproduction. ...
speciation.
