Isn't our kind, homo sapiens, subject to the same forces of darwinian natural selection as all other species the most obvious reason for thinking our natural evolution has ceased is that we're just a single species. This is the process known as natural selection that's the essence of natural selection and so adaptation and human evolution go on all the time as a species sapiens about sapiens.
