I am always amazed at the so-called mainstream media. They know very little about their topic, depend on biased experts and tend to poorly inform their readers about factual relationships of similar topics, such as "exo-genes".
There are many varieties of genetic codes within our bodies, and this is only one of those codes. Some of these codes, the exo genes can affect the other genetic codes.
It seems that the New York Times does have some reporters highlighting what is being discovered through genetic analysis. One article is called, The DNA Age by Amy Harmon.
