The ancient Greeks already had noticed that it's what goes on but Darwin was the first to write down his ideas into a surviving book, with a lot of detailed observations.
natural selection
Adaptation is the result of natural selection.
by natural selection.
Yes, natural selection is always occurring.
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.

natural selection
Adaptation does not allow for natural selection: natural selection causes adaptation.
Some have thought so because natural selection was seen to reduce variation by culling unsuccessful phenotypes so that alleles did not change over time in populations. This is no longer thought as much as the rates of mutation are better understood and known to outpace natural selection and that adaptive change can accommodate more than one successful phenotype so that many allels can be fixed in populations gene pools.
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
Natural selection is what causes adaptation.
No, natural selection is the mechanism that drivesevolution.
