Is Human Evolution dead as we know it? I have been posing this question to myself. No one else talks to me so I might as well. Has Human evolution stopped? If you are a creationist or other similar believer please stop reading now.
The general scientific viewpoint is that the evolutionary process as described by Darwin and others is how all lifeforms on planet Earth (and anywhere else) evolved via genetic mutation based on survival of the fittest. To be blunt this means that only the strongest survive. In relatively modern times (given billions of year of Earth’s history) the study of this has had bad implications from Eugenics to the Nazi’s but have we as a species also caused our own problems.
Many of you will be aware of the Darwin Awards which describes anecdotal or sometimes real incidents where Darwin fights back against stupidity of human beings but I would like to widen the discussion into two areas. Health and Safety and Dentistry. The medical arguments would only cause anger and allegations of discrimination whilst missing the point.
Health and Safety
An example from the Olympics at the weekend. The leading rider crashed in the women’s race the day after 2 of the leading men’s race riders had done a similar thing. This prompted all and sundry to complain about the safety of the course. No one mentioned that the riders should have ridden slower to ensure they got around the bend(s). Likewise at work we have become accustomed to the H&S rules dictating everything from ladder positioning to what height out seat should be. All of this is taken care of now and policed by a range of rules and legislation. Thus preventing a range of actions that would have killed off sections of the public who seem to have lost the ability to think for themselves. i.e. crossing roads by looking both ways not whilst reading your phone with headphones in/on. Instead build more barriers and post warnings not to do this. So the stupid idiots who lack common sense are maintained in the gene pool to reproduce and create more idiots who will then have to be protected from their own stupidity. Of course if our ancient ancestors had not played with fire we would not have developed the means to use it. Playing with a busy road may not be the best way of progressing the brainpower of our species, although car brake engineering has come on leaps and bounds.
Sexual attraction (and consequent mating) is based on physical attractiveness our use of dentistry to improve looks is now hiding genetic failure. If you genetically have bad teeth a trip to the dentist will help, but your future mate would not know what’s hiding in the genes or jeans. This Dentistry is denying Darwin. Of course dentistry also improves health due to lack of cleaning teeth but thus bad teeth genetically continue. Darwin reversed or blocked. The same is true of course of other medical advances.
Countering My Own Argument
Of course the keeping of genetic mutations which might otherwise die out also means that the genetic spectrum is wider thus potentially more scope for greater and more diverse development. Then there is the impact of gene splicing or other genetic manipulation either before birth or via stem cells/medical implant to remove certain diseases or hereditary illnesses.
Who knows perhaps in 10,000 years we will all have perfect teeth at birth and live as long as we want.
