Natural selection is the non-random differential reproductive success of variant traits. The assumptions it rests upon are:
- That life reproduces with variation in inherited traits.
- That a population always produces slightly more offspring than can comfortably subsist in its niche.
- That offspring therefore, directly or indirectly, compete for resources and mating opportunities.
- That differences in inherited traits affect the average number of fertile offspring raised by individuals.
- That traits that allow their bearers to raise a higher average number of fertile offspring spread throughout the population faster than rival traits.
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.
No, natural selection works on that genetic variation presented to it.
One big Hardy-Weinberg assumption is that there is no mutation taking place in the population of interest. Mutation and selection lead to evolution, which the Hardy-Weinberg assumption also does not allow in a population. So, if there is the variation brought about by mutation then there is a chance of natural selection happening and this violates Hardy-Weinberg assumptions.
Natural selection is what is most closely associated with Darwin.
Charles Darwin is associated with the theory of evolution by natural selection, which explains how species evolve and adapt to their environments over time through the process of natural selection. He is best known for his work on the origin of species and the idea that all living organisms are descended from a common ancestor.

Darwin made bold assumptions about heritable variation, the age of Earth, and relationships among organisms. First, in order for beak size and shape to evolve, there must be enough heritable variation in those traits to provide raw material for natural selection. Second, differences in beak size and shape must produce differences in fitness that cause natural selection to occur.
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.
