Actually, new genetic material is introduced all the time. Bacteria spontaneously mutate, but more relevant here is that our Drug ABC, is an antibiotic. Antibiotics prompt bacteria to mutate, changing the genetic material.
All that happens is that genes with a pre-existing resistance (or ability to borrow said resistance) survive to propagate.
LOL.
So what is the new gene (read: data) that appears?
Directed mutation is anathema to Darwinian's. Get with the program.
A bit of good news however, evidently Chavez lost the referundum and Venezuelans said NO to totalitarianism.
