Artificial selection.
Your brain is one of the most important human features evolved by natural selection. ( perhaps sexual selection also had something to do with it )
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.

No. They function through the exact same mechanisms. The only difference is what controls the environment: whether it is in human hands or left to nature.
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.

The process by which humans breed organisms to obtain certain traits is known as artificial selection.
Breeding.

The four forces of human evolution are mutation, genetic drift, gene flow, and natural selection. Mutation introduces new genetic variations, genetic drift refers to random changes in gene frequencies within a population, gene flow involves the transfer of genetic material between populations, and natural selection is the process by which certain traits become more common in a population due to their advantage for survival and reproduction.

To a very low extent, yes.
