Junk DNA is an unfortunate choice of name, since it immediately devalues this portion of DNA because of its as yet un-ascertained purpose.
It is prejudice to assume that, just because we do not know what purpose it serves, it is of no value and can be tampered with and manipulated to serve short sighted aims of a few individuals.
Investigation of its purpose and any coding within it is however a useful scientific endeavour, as we may be wiser as a result.
Very often human technology which should benefit mankind has been found to have unforeseen detrimental effects.
The distinction between life and machine, biology and technology, must always be preserved because when life is devalued its very survival is threatened. This is of primary importance.
Unfortunately it is the distinction between science and fantasy that is becoming blurred.
Economics and technology (and a certain percentage of human beings) are devoid of morality.
Question? Shouldn't common sense, foresight and moral values hold tight to the reins of technological development?
