Natural selection can lead to individuals with certain combinations of polygenic traits having higher fitness, increasing their likelihood of passing on their genes to the next generation. It can drive the frequency of alleles that contribute to favorable trait combinations up or down in a population over time. Natural selection can influence the distribution of phenotypic variations for polygenic traits, favoring those that provide a survival or reproductive advantage in a specific environment.
In many ways. For one thing, evolution and natural selection are mindless processes; they act without regard for the rights to happiness or life of the individual. On the other hand, human civilization has throughout history tried as much as possible to move away from blind forces of nature like natural selection, and as a result, human populations now may harbour many genes that would, under less civilized circumstances, have detrimental effects on human survival chances.

Natural selection is more of an evolutionary factor than a stabilizing factor, but one could argue that the end result of evolution is an organism that is perfectly adapted to its ecological niche, in which case stability will result.
Three ways with which humans interact with the environment include dependency for livelihood, to modify it and adapt to conditions.

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.

he discovered natural selection and the theory of evolution
stabilizing selection: when individuals near the center of the curve have a higher fitness than individuals at either end of the cure, keeping the center at its current location but narrows the overall graph directional selection: when individuals at one end of the curve have a higher fitness than individuals at the other end, or middle, causing the entire curve to move as the character trait changes disruptive selection: when individuals at the upper and lower ends of the curve have higher fitness than individuals near the middle, causing the single curve to be cut into two These three types of selection are brought about by natural selection, so whichever one is favored, then the genes evolve in that specific direction. natural selection acts on the genotype, but the results are seen in the phenotype

Natural selection changes the genetic makeup of a population by favoring some genotypes over others. It does so through the differential reproduction of those genotypes. Put simply, if I possess a variant of a trait (and the genotype underlying it) which allows me to leave behind more adult offspring than those with different variants of that trait, then my variant will become more common in the population than the others. The result is a change in the frequency of the gene variants: mine increases in frequency at the expense of the others. This change in the frequency of gene variants (known as alleles) over time in a population is the basic definition of evolution itself.
