Much of "On the Origin of Species" comes from Darwin's studies of farm animals and domestic livestock. While human selection is NOT natural selection, selective breeding can be seen as an accelerated, exaggerated and unnatural version of the same process. Farmers know it works, and were, after all, the ones who started the practice thousands of years ago.
Abiogenesis, or more commonly known as the origin of life itself, is not part of Darwin's theory of evolution.
Evolution by natural selection can be described as a robust scientific theory. In scientific terms, a theory is not merely a guess; it is a well-substantiated explanation based on a body of evidence and observations. While specific mechanisms and details may continue to be refined, the overarching framework of evolution by natural selection remains supported by extensive empirical data, making it a foundational concept in biology.
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.
Evolution by natural selection can be described as a scientific theory. In scientific terminology, a theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence and has withstood rigorous testing and scrutiny. While it has not been proven false, it remains open to refinement and further testing as new evidence emerges.

Inheritance of acquired characteristics is not one of Darwin's four main ideas of natural selection. His four main ideas are variation, competition, heritability, and differential reproductive success.

Alfred Russel Wallace independently developed ideas of natural selection around the same time as Charles Darwin. In 1858, both Wallace and Darwin jointly presented their findings on evolution and natural selection, leading to the publication of Darwin's "On the Origin of Species" in 1859.
