Natural selection helps to increase biodiversity and the number of new species.

Non-random mating is otherwise known as sexual selection. Some see this as distinct from natural selection, but I think that sexual selection is merely a form of, or perhaps more a complication of natural selection. Selection, natural or sexual, is the effect that "guides" evolution, that allows evolution to produce populations suited to their environment.
Variation in the organisms under selection. In both artificial selection and natural selection there must be heritable variations that have the possibility of being in the case of artificial selection what the selector wants in the organism and in thje case of natural selection survivability and reproductive advantages.
Technically, one should say that natural selection is a theory that explains a set of observations. However, the theory has been substantiated to such a degree that one might as well call it fact.
No. Natural selection works in all populations. However, new alleles spread more slowly in large populations; the large size has a stabilizing effect. So one should expect large populations to change more slowly than smaller populations.

Natural selection is one force that can lead to evolution.natural selection is one cause of evolution
Theo is the solution
How does natural selection affect undesirable traits?
it would die
Natural selection is one of the 'guiding' principles of evolution.
They are the selective agent in natural selection ;)
Natural selection is one of the mechanisms that shapes adaptation and enables evolution.
The individual organism is selected, or the genes that reside in this individual organism.
