Human Evolution - no more?

Human evolution has been the subject of debate for just about the entirety of its existence. It has been discussed, argued, and criticized for centuries. But where to now? Has the human race reached the point in its development at which it no longer reacts to its environment, changing according to Darwin’s theory of natural selection, but changes its environment to suit itself? Think about it. At one stage, if something stopped humans from achieving something, then it would direct human development according to how successful we were at achieving it. Now, we simply create something that will achieve it for us. The reason we are considered the most intelligent race on earth we must remember, is our ability to create machines.

The theory of natural selection still applies to everything else, but not humans (well not anymore anyway). If we don’t like something, then we change it so that we do. Similarly, we have reached a point in medicinal progression at which we can now cure just about every disease that would otherwise affect the course of human development. This obviously has a similar effect. However, this has a less noticeable effect on developing countries, for obvious reasons.

But, is this necessarily a good thing? It is through our ability to alter our environment in order to stop it from affecting us that we are potentially growing into a weaker race. Diseases that at one stage would have run the course of natural selection (sorting the men from the boys so to speak), are now simply killed off, because we can. Obviously this is a good thing in terms of our general development, and it allows us to continually increase things such as life expectancy and the like.

However, this lack of effective natural selection (particularly in developed countries), is likely to be countered in a number of ways, including the continual immigration of developing peoples into industrial communities, and future use of genetic manipulation and intentional breeding. So there’s not a lot to be worried about. Apparently.

As always, it’s been a pleasure to empty the contents of my mind onto the floor, sort them out and provide you with the interesting bits. If you have any thoughts on the matter, or any discussions that you would like to be raised in the future, please leave a comment. Thanks
