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 )
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.

genetics correlate with drug dependence
the difference between the 2 r that natural is the best looking or tasting and artificial is fake
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.
mutation brings about variation which is the basis of evolution and the two types of variation are heritable and non-heritable
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 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).
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 is a future generation, and a natural selection is when the Natural Resources select the generation continued. Natural selection is the evolutionary driver of adaptive change. All organisms born are variations and the variation that survives and reproduces better than its conspecifics will have more progeny with the selfsame adaptation that helped the organism to survive and reproduce. Thus, through mutation leading to variation and mutations leading to improvements on that variation natural selection chooses and shapes the organism to be well adapted to its immediate environment.
Natural selection is the process by which certain heritable traits in a population are favored, leading to their increased frequency in future generations. Phylogeny, on the other hand, is the evolutionary history and relationships among organisms. Natural selection plays a key role in shaping the characteristics of species over time, influencing their phylogenetic relationships as some traits become more prevalent in descendant species.
