Natural selection is, simply put, the nonrandom survival and reproductive success of randomly varying organisms.
Variation
more born than can survive
better adapted selected
traits passed on to progeny
alleles change in populations over time
Random processes are not part of the theory of evolution by natural selection. Excepting random genetic mutation that provides the variation natural selection works on.
Extinction is part of the Theory of Evolution. This goes along with natural selection and survival of the fittest. Organisms that go extinct do so because they are no longer able to survive in the habitat.
Animals that survive cannot pass along their adaptation
Darwin developed The theory of evolution by natural selection.So, to answer you question, all of it!You need to make a distinction between evolution, the change in allele frequency over time in a population of organisms, and natural selection, the nonrandom survival and reproductive success of randomly varying organisms. Natural selection is the main driver of evolution.
Evolution states that a species will change to become more suited to its environment. Natural selection is survival of the fittest. The newly evolved version of the species is more fit to survive, therefore thriving.

New generations are better suited to survive than previous generations.
It didn't, actually. While natural selection isn't the complete story of evolution, it is the single most important part of it, and all discussions of evolution must inevitably involve natural selection in some form.
Abiogenesis, or more commonly known as the origin of life itself, is not part of Darwin's theory of evolution.
which is not part of darwins theory of natural selction

If you're referring to "sexual reproduction" and the theory of evolution, then yes. It plays a major part in the evolution of organisms which use it, as it offers major advantages.
That's part of the theory of evolution by natural selection (Darwinism) but not the main principle, and some other (obsolete) theories also included this belief. I don't know if there is a more specific answer, but if you can't find one, just go with natural selection.
