The individual, or the genes of the individual.
All organisms are variants in phenotype and behavior. So, natural selection is the immediate environment these organisms are in and those that survive and reproduce better in this environment leave more descendants which carry the genes that promoted that survival and reproduction advantage. Then those genes are more represented in the populations gene pool and this is evolution.
Natural selection selects genes.
This type of natural selection is called stabilizing selection because the mean traits of the population are being selected for against the immediate environment.
Populations evolve, but individuals are selected. Natural selection affects individual organisms.
Natural variation in artificial selection is used because humans choose from among the naturally occurring variation s in species. Natural selection is related to species fitness because Darwin called natural selection survival of the fittest because those that could survive would carry their species on there for being the naturally selected.
natural selection is a passive prosess . the mechanism of some individuals to be selected more than others is because they fit their environment more. and phenotype shows the fitness .
The moths which were less camouflaged were naturally selected for dinner by birds.
This type of natural selection is called stabilizing selection because the mean traits of the population are being selected for against the immediate environment.
Think GMO crops. Not natural selection, we selected them artificially

Because diseases are being naturally selected to resist attack and be better infectors of humans.
Disruptive selection, also known as diversifying selection.
Natural selection is the nonrandom survival and reproductive success of randomly varying organisms selected against the immediate environment. Like that. Remember this little explanation and you have natural selection down pat
What would be selected if organisms did not have differences that lead to better survival and reproduction, or the opposite. That is all natural selection is.
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.
Natural selection explains the process of evolution: evolution by natural selection. It basically means that species with the highest fitness (survival rate) will live, and be selected by nature for the characteristics they possess that make them more apt to survive. Because of natural selection, evolution occurs.
