What takes longer selective breeding or natural selection?

Selective breeding takes a shorter amount of time compared to natural selection. In selective breeding, humans artificially select and breed organisms with desirable traits, allowing for rapid changes in specific characteristics within a few generations. On the other hand, natural selection is a slower process that occurs over many generations and relies on the chance occurrence of beneficial variations and their survival and reproductive advantages within a population. Selective breeding can yield specific desired outcomes in a relatively shorter time frame compared to natural selection.
