After observing nature for some time, Darwin came to believe in natural selection causing a change in the evolution of species.
Natural selection - is allowing the species to breed at their own convenience - with whichever member of the opposite sex they choose. Artificial selection is human intervention in that natural process - allowing breeders to choose the best genes for the species.
1. That all species shared a common ancestry. 2. These species did not survive by chance, but by natural selection.
Artificial selection is anthropogenic -- humans interfere with nature to determine what traits get passed on, whereas natural selection is when through sexual reproduction the traits passed on are determined by survival of the fittest.
In a sense, one might say that this is the case. But in a more direct sense, natural selection determines which organisms do not get to procreate (as much). Natural selection is therefore more a limiting phenomenon than an enabling one.

natural selection for example is a peppered moth.
Yes, artificial selection or selective breeding can be a good analogy for the selection that occurs in nature through natural selection. Both processes involve the intentional or environmental selection of traits that are beneficial for survival and reproduction, leading to changes in populations over time.
Natural selection usually causes a species to change gradually

This is called biomimicry.
Natural selection explains the process of evolution: evolution by natural selection. It basically means that species with the highest fitness (survival rate) will live, and be selected by nature for the characteristics they possess that make them more apt to survive. Because of natural selection, evolution occurs.
Nature plays no direct role in artificial selection. That is the difference between artificial selection and natural selection. Nature does play some indirect roles in artificial selection. One indirect role is in providing the organisms with which one beings the artificial selection. Another is in influencing the choices of the organism performing the artificial selection.
Natural selection. Which ultimately leads to evolution.Or God. Depending on your beliefs.
natural process means which is occuring by nature. for example- evaporation
