With more than thirty thousand genes in your body, you can't expect them all to have cool names.
Now we are at the third order: splicing genes within a species.
Some of it is known, but the function of each of the thirty thousand genes has to be figured out one at a time.
Finally, we get to the fourth order of GMO: being able to splice genes from one species into another species, a process known as transgenesis.
Then, people could start reporting all their medical issues—headaches, halitosis, heart disease—and we will begin to see commonalities between genes and conditions we do not generally regard as genetic.
