Simply put.
Mutation, variation and selection against the immediate environment.
No - natural selection does not create new alleles. Variation in alleles needs to exist in the population in order for natural selection to occur. Natural selection will involve the change in allele frequencies over time, but it does not create new alleles. New alleles are the result of mutations.
This process is called natural selection. It is the mechanism by which traits that provide a survival or reproductive advantage to an organism become more common in a population over time.
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
It hasn't. Natural selection is a key part of the ecosystem itself.
Natural selection is the mechanism primarily responsible for the development of today's biodiversity.

Adaptation does not allow for natural selection: natural selection causes adaptation.
The prefix of natural selection is "natural" and the suffix is "-tion".
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
Natural selection requires variation in traits within a population, differential survival and reproduction based on those traits, and inheritance of those traits from one generation to the next. These factors allow for the gradual accumulation of advantageous traits over time.
Natural Selection
Natural selection.
That selection was natural.
Natural selection is what causes adaptation.
No, natural selection is the mechanism that drivesevolution.
Natural selection
Yes, natural selection requires genetic variation to drive the process of evolution. Genetic variation provides the raw material for natural selection to act upon, leading to changes in the traits of a population over time.
