Natural Selection is made up of 5 parts which is:
Animals that survive and produce a lot of offspring so if some die they still have some offspring left.
Within a species, or group, of animals these are Variations Ex: some are tall short etc.
Variations are passed onto offspring.
Some Variations allow some animals to live and others to die.
Overtime those with the best Variations live & therefore makeup most of the population.
Natural selection is driven by differences in reproductive success between variants within the same population.
Gradualism isn't a prediction of natural selection, but of our understanding the mechanisms that produce reproductive variation. Natural selection makes predictions about allele frequencies in populations and reproductive fitness.
Natural selection and Mutation
If treat it properly
Darwin
Crossing-over increases the genetic variation within a population, which is required for natural selection to act upon.

natural selection
Adaptation does not allow for natural selection: natural selection causes adaptation.
The store that has the greatest selection of ipod covers is the Apple store. Since Apple makes the ipod, it is natural that the Apple store has the greatest selection out there.

Stabilizing selection occurs when the extreme forms of some trait are selected against by natural selection. It is a force of natural selection which causes evolution (definition: change of allele frequency in a population divided by time).
