Natural selection is the nonrandom survival and reproductive success of randomly varying organisms.
Evolution is the change in allele frequency over time in a population of organisms.
So, the individual naturally selected will leave more decedents in the population and his descendents will have the traits that made him survive and reproduce better and this will change the allele frequency of the population, the population's gene pool, and lead to evolution in this population.
In Darwin's theory of evolution by natural selection, the environment is a key driver of the process. Organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to the next generation. Environmental pressures, such as competition for resources or changes in climate, drive the process of natural selection by selecting for traits that increase an organism's fitness for survival.

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 environment plays a key role in natural selection by exerting pressures that favor certain traits over others. Organisms with advantageous traits for a specific environment are more likely to survive and reproduce, passing on those traits to future generations. Over time, this process leads to the selection of traits that are well-suited to the specific environmental conditions of a given area.
These plants and animals were subjected to artificial selection so that the traits humans wanted in the organisms were selected for and the organisms not having these traits were culled. This, with some modification, is a good analogue for natural selection and artificial selection shows how organisms can be shaped over time with the proper selective pressures. The selective pressure of humans in artificial selection and the selective pressure of the environment in natural selection.

Nature plays no direct role in artificial selection. That is the difference between artificial selection and natural selection. Nature does play some indirect roles in artificial selection. One indirect role is in providing the organisms with which one beings the artificial selection. Another is in influencing the choices of the organism performing the artificial selection.

Heritable variations play a crucial role in Darwin's theory of natural selection as they provide the raw material for evolution to act upon. These variations are inherited from parents to offspring and can affect an individual's ability to survive and reproduce in a given environment. Natural selection then acts on these variations, with individuals better adapted to their environment being more likely to survive and pass on their favorable traits to the next generation.

Natural selection does not respect the rights of the individual. If you care for the rights of the individual - your own, for instance - you should avoid being naturally selected against. Fortunately, humans have expanded their control over their environment to such a degree that natural selection no longer has the role in our development that it has for 'wild' life forms. This makes it somewhat easier for us to consider the phenomenon of natural selection from an objective stance.
The environment plays a significant role in evolution by exerting selective pressure on individuals with certain traits. These individuals are more likely to survive and reproduce, passing on their advantageous traits to the next generation. Over time, this process leads to the adaptation of species to their environment through natural selection.

Charles Darwin used data on artificial selection the least to support his theory of natural selection. While artificial selection played a role in shaping his understanding of how traits can change over generations, he focused primarily on observations of variation in nature and the role of competition and adaptation in driving the process of natural selection.
Meiosis plays a role in the process of natural selection by generating genetic diversity through the shuffling of genes during the formation of gametes. This genetic diversity contributes to variation within a population, which is crucial for natural selection to occur as individuals with advantageous traits are more likely to survive and pass on their genes to the next generation.
The harsher the environment the more natural selection plays a role because the smallest advantage might be enough, hence humans with a very easy environment where genes don't offer a significant advantage this doesn't really count for humans. And how much a species reproduce, the more they reproduce the more chance for a beneficial mutation.
