Artificial selection tends to occur more quickly than natural selection because it involves intentional breeding by humans to promote desired traits in organisms. This focused approach can lead to rapid changes in specific characteristics over a few generations. In contrast, natural selection operates through environmental pressures and can take much longer for significant changes to occur, as it relies on random genetic variations and survival advantages over time.
no there is no genetic variation for natural selection to act upon
Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.
The antonym of "artificial" is "natural." While "artificial" refers to something made or produced by human beings, often imitating something natural, "natural" describes things that occur in nature without human intervention. Examples include natural foods, materials, and processes.
Natural selection requires variation in traits within a population, heritability of those traits, and differential reproductive success based on those traits. Without these components, natural selection cannot act on a population.

Artificial selection demonstrated that desirable traits could be purposefully selected and passed down in domesticated plants and animals. This helped Darwin understand that similar processes could occur in nature through natural selection, where organisms with advantageous traits are more likely to survive and reproduce. This supported his theory of evolution by natural selection.
Artificial selection interested Darwin because it demonstrated that traits could be modified over generations through selective breeding. This process allowed humans to intentionally choose which traits were passed on to offspring, leading Darwin to realize that a similar natural process could occur in nature, driving evolution through natural selection.
There are really no steps in natural selection - just conditions required for it to occur.
What population? Perhaps you mean if there were no variation for natural selection to select from.

A lot of natural selection occurs very slowly. It took the evolution of the dog from the wolf to take at least 14,000 years. It took singled celled life 3+billion years to evolve into multicellular life.
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
