We cannot visually observe natural selection happening in real time because it occurs over generations and may take thousands of years to become noticeable. However, we can study its effects by observing changes in populations over time and see how traits become more common or rare.
Natural selection will see to it that genes from the strongest and more fertile bucks and does are passed down susequent generations.
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.
Natural selection will see to it that genes from the strongest and more fertile bucks and does are passed down susequent generations.

Adaptation does not allow for natural selection: natural selection causes adaptation.
Nice? The theory of evolution by natural selection is the best and best supported explanation for the fact of evolution we have, but it just is and a word such as " nice " would not always fit theory. Google Ichneumon wasp to see that natural selection is not always " nice. "
Everything from available food to climate will cause the changes we see in natural selection. Random mutations occur constantly and when those mutations are beneficial for life, the genetic code is more likely to be passed on to future generations.
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
Natural selection.
That selection was natural.
Natural selection is what causes adaptation.
