Evolution is meant to have its limits, it is not meant to be everything, and it is meant to be understood within those limits; otherwise it will set limits to our understanding, otherwise we will tend to see it as the it that is meant to make possibility possible.
We see nature revolving around evolution and its possibilities, instead of looking at evolution revolving around nature and its possibilities. We see things change and call it evolution, and then we say the evolution explains the change. Yet evolution is not everything. It does not determine the possibility of what can happen, though it certainly appears to – that is, if certainty can be attributed to appearances. But did Copernicus not teach us a lesson in that regard?
“It’s true to say that evolution is not an ascent. There is no march towards complexity in evolution.” Professor Brian Cox. (20.10.14). http://www.bbc.co.uk/news/science-environment-29686627
