As scientists are busy manipulating the genes of edibles including corn, soybeans, canola, papaya, zucchini, and now rice and salmon, an interesting fact comes into light about what exactly scientists know and don’t know about human genes. According to geneticist Steven Salzberg of the University of Maryland, “Not only do we not know what all the genes are – we don’t even know how many there are.”
Genetically manipulated foods have been found to change the genetic structure of our healthy bacteria – and this makes one wonder if GMO foods might be altering our own genetic make-up as well. But if they are, how would we know? By a geneticist’s own words, scientists can’t even find all of our genes – let alone know what they all do or how they’ll act if they are changed. In addition, one gene often controls several different things – and with scientists not even knowing all of the genes we have, it makes it pretty difficult to know where to look when things start going wrong – and next to impossible to fix.
