Natural selection is not [[mutation]]. It does not make anything new, alter anything, etc... Natural selection can cause extinction based on survival of the fittest, but the processes of creation and mutation lie outside the scope of natural selection. Natural selection simply "selects" from what variation available at that specific moment, this variation having been caused by mutation. [[Evolution]] is the process of mutation followed by natural selection.
