yes natural selection takes place without human control. In natural selection it is the environment selecting the traits/alleles. However there is something called artificial selection which is evident in dog breeding. In that case humans select for the traits. Artificial selection can have detrimental effects on a population though. Some dogs have been selected for being very small and having a flat nose. These dogs are so small now that they cannot give birth naturally and have no use of their nasal passages
Your brain is one of the most important human features evolved by natural selection. ( perhaps sexual selection also had something to do with it )
.
In many ways. For one thing, evolution and natural selection are mindless processes; they act without regard for the rights to happiness or life of the individual. On the other hand, human civilization has throughout history tried as much as possible to move away from blind forces of nature like natural selection, and as a result, human populations now may harbour many genes that would, under less civilized circumstances, have detrimental effects on human survival chances.
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.
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.
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.

natural selection occurs due to natural phenomena (e.g. changes in diet or predators).artificial selection occurs due to human generated phenomena (e.g. breeding or domestication).
To a very low extent, yes.
In many ways. For one thing, evolution and natural selection are mindless processes; they act without regard for the rights to happiness or life of the individual. On the other hand, human civilization has throughout history tried as much as possible to move away from blind forces of nature like natural selection, and as a result, human populations now may harbour many genes that would, under less civilized circumstances, have detrimental effects on human survival chances.
Natural selection is when contemporary species rose from ancestors that survived due to their physical characteristics in their habitats. A well-known example is the Galapagos Islands and how the animals on the islands adapted to their environments. Darwin convinced the biology world that diversity in organisms came from evolution (descent without modification). Artificial selection is when humans intentionally breed animals for certain traits. Unlike natural selection, where only the fittest survive, artificial selection is for human's likings. Many crops that are grown are part of artificial selection.
Notincluding human intervention. Natural selection.
According to Darwin's theory of evolution by natural selection, human beings evolved through a process of genetic mutation and adaptation over millions of years. Through this process, early hominids gradually evolved and developed traits that resulted in the modern human species.
