Natural selection is one of the mechanisms that shapes adaptation and enables evolution.
Natural selection is most closely related to Darwin's theory of evolution.
No, natural selection is believed to result in evolution.
Perhaps not, but evolution can exist without natural selection.
Evolution by natural selection.
Evolution by natural selection.
Natural selection is the process of certain animals being more successful than others and thus reproducing more. It is the driving force behind evolution as we currently understand it.
Natural selection directs evolution; it cannot stop or prevent it.
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.
In evolution, natural selection is often called survival of the fittest.
All natural selection results in evolution. But natural selection is not necessarily the only mechanism leading to evolution. There are processes at work on a molecular level, such as intragenomic conflict-type processes, that also result in differential reproductive success, but aren't exactly related to the kind of processes Darwin first described.
A mutation is any change in the DNA. Mutations provide the genetic variation that evolution by natural selection needs to select from.
Random processes are not part of the theory of evolution by natural selection.
