Human selection, also known as artificial selection, is the process in which humans intentionally breed plants or animals with desirable traits to produce offspring that exhibit those traits. This selective breeding helps to enhance specific characteristics such as size, color, or behavior over successive generations. Human selection is widely used in agriculture and animal husbandry to create domesticated species that better suit human needs.
Artificial selection.
Human choice or preference substitutes for naturally occurring selection pressures in artificial selection. Instead of environmental factors determining which traits are advantageous, human breeders actively select for specific traits, leading to changes in the gene pool of the population.

Aside from both being natural selection, not much. Let us use height in humans as our example.Stabilizing selection, the regression to the mean, keeps the height of humans pretty much with a normal distribution as the human environment is the whole earth. So humans are not too tall, or too short, generally ( pygmies excluded ), over all the human range and various environments.Now, with directional selection there would be a tendency for the human population to grow taller, or shorter over generations. We have seen this effect on humans in ancient times, Homo florensis, but in modern time stabilizing selection of human height, averaging out, is the norm.
Natural selection is the process by which organisms better adapted to their environment tend to survive and reproduce, leading to evolutionary changes over time. In contrast, artificial selection is the intentional breeding of organisms by humans to promote desired traits, such as in agriculture or pet breeding. While natural selection occurs without human intervention, artificial selection is guided by human preferences and goals. Both processes can lead to changes in species, but their mechanisms and driving forces are fundamentally different.
Artificial selection.
Sociobiology is the application of natural selection to human society Humans are the product of natural selection at the individual level and the product of evolution at the population level, so the human generated society is influenced by the natural selection of individual humans.
accelerated rates of natural selection due to human involvement.. natural selection caused by human intervention.

Yes. Constantly.
Human choice or preference substitutes for naturally occurring selection pressures in artificial selection. Instead of environmental factors determining which traits are advantageous, human breeders actively select for specific traits, leading to changes in the gene pool of the population.
The process by which humans breed organisms to obtain certain traits is known as artificial selection.

No, directional selection can also occur in response to human activities such as selective breeding and environmental changes caused by human intervention. It can also occur in response to human-imposed selection pressures in agriculture and other industries.
Artificial selection in biology is the process by which humans intentionally breed organisms with specific traits to produce offspring with desired characteristics. This differs from natural selection, which is the process by which environmental factors determine which traits are advantageous for survival and reproduction in a given population. While natural selection occurs in nature without human intervention, artificial selection is driven by human choices and preferences.
