While surfing around I noted a certain paragraph. quote:
CRISPR stands for “clustered regularly interspaced short palindromic repeats”—clusters of brief DNA sequences that read similarly forward and backward, which are found in many types of bacteria. Scientists first observed the puzzling DNA segments in the 1980s but didn’t understand for almost two decades that they are part of a bacterial defense system. When a virus attacks, bacteria can incorporate sequences of viral DNA into their own genetic material, sandwiching them between the repetitive segments. The next time the bacteria encounter that virus, they use the DNA in these clusters to make RNAs that recognize the matching viral sequences. A protein attached to one of these RNAs then cuts up the viral DNA. "Hang on." I said, "I should read that again." So I did. The article is here : http://www.technologyreview.com/review/524451/genome-surgery/ Might be worth your time and on topic, because, If Aliens from beyond the Bowling Alley invaded and monkeyed with the monkeys, they wouldn't have to know much more about genetics than we know now. Also, the bacteria under discussion seem pretty capable genetic engineers, though they seem to have no brains at all. The lateral transfer of genetic code by force seems to differ radically from Evolution as described in Darwin's Thesis. For one thing, reproduction is not the gene transfer mechanism. For another, the code is chosen based on the use it can be put to. Nothing random about it. That says a lot about the possibilities, in regard genetic surgery.
