It is clear that natural selection is no longer as powerful as it has been centuries ago but it still exists. Additionally to that, even if humans have evolved due to random micro changes in the DNA now we are able to enhance our power,memory, vision etc through artificial intervention (including chemicals). Furthermore, culture “imposes" us beauty and performance criteria such as beauty for example reducing on the long term the pole of genes (it is a little farfetched,I admit). Natural selection” is now human made. Having in mind all this I do like your analysis on the matter.
