Natural selection is the preferential survival of individuals with useful traits. On the other hand, when some individuals survive, others don't, either because they are out competed for resources or because they are simply killed. This is extinction!
A hypothesis is an educated quess while a theory is a widly supported idea. The relationship between them is that they both aren't necessarily correct. An example of a theory is the theory of evolution and natural selection. They have a lot of facts to back them up, but there is no inconclusive evidence to prove they are laws of science.
Natural selection is survival of the fittest, while sexual selection is a preference for a given trait made by the limiting sex. It is strangely, but usually in opposition to natural selection (E.G., male peacock's tail feathers that garner attention from predators and prevent the peacock from fleeing well).
Adaptation does not allow for natural selection: natural selection causes adaptation.
The selection of the organism that survives best in a habitat with limited resources and that organisms superior reproductive success is called natural selection.
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
Here is a quote: "The relationship between adaptation and natural selection does not go both ways. Whereas greater relative adaptation leads to natural selection, natural selection does not necessarily lead to greater adaptation." I do not recall who said it, but this is what the relationship between both is. Here is a quote: "The relationship between adaptation and natural selection does not go both ways.

Natural selection.
Natural selection ' selects ' from among variations. Some organisms are better suited to their immediate environment and survive and out reproduce other organisms. All these organisms are genetically variant. That is the simple connection between natural selection and genetic variation. ( that variation coming about by mutation and recombination )

Natural selection is more efficient ad more precise.
Purifying selection removes harmful genetic variations, while positive selection promotes beneficial genetic variations in natural selection.
Evolution is the process of change in species over time, while natural selection is a mechanism by which evolution occurs. Natural selection acts on genetic variation within a population, favoring traits that increase an individual's chances of survival and reproduction in a given environment. Over time, these advantageous traits become more common in the population, leading to evolutionary change.
Natural selection drives the adaptation of organisms to their environments by favoring traits that enhance survival and reproductive success. This process can lead to increased diversity as populations adapt to different niches and conditions, resulting in varied behaviors and physical characteristics. Conversely, organisms that cannot adapt to changing environments or compete effectively may face extinction. Thus, natural selection is a key mechanism influencing both the diversity of life and the survival of species.

A hypothesis is an educated quess while a theory is a widly supported idea. The relationship between them is that they both aren't necessarily correct.

natural selection occurs due to natural phenomena (e.g. changes in diet or predators).artificial selection occurs due to human generated phenomena (e.g. breeding or domestication).
Three processes that have affected the history of life on Earth include natural selection, mass extinction events, and evolutionary diversification. Natural selection drives the adaptation of species to their environment, mass extinction events change the course of evolution by wiping out many species at once, and evolutionary diversification leads to the emergence of new species over time.
