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.
By science
The numbers of birds with different beak shapes are changed by natural selection in response to the available food suply.
It really doesn't. It's just what we choose to do with our electrons.
In all natural processes, there is an element of chance. In natural selection, most of that chance is introduced by the randomness of the genetic variations it works with. But other elements of chance exist as well. Natural selection is a stochastic phenomenon: not every less able variant will produce less offspring than the more able variant; much depends on chance environmental circumstances.

A mutation is any change in the DNA. Mutations provide the genetic variation that evolution by natural selection needs to select from.
Yes it does. For example, "She pioneered the student graduate scheme" or "Charles Darwin pioneered the natural selection theory of evolution"
natural selection
Adaptation does not allow for natural selection: natural selection causes adaptation.
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
Its a chicken and egg situation. Adaptation is the response to Natural Selection, and Natural Selection is the response to Adaptation. They both operate by the principle: the members of any species that are best adapted to their environment are the ones most likely to survive and reproduce the next generation, where the process repeats. That does not mean the strongest or most aggressive, they often get themselves killed off.
Natural selection is what causes adaptation.
