The folks in white lab coats and low
shoes with letters after their names are up to their old tricks again in
attempting to build the super cow of the future. And please note I said
“build,” not “breed.” It seems the gestation length of the bovine is
much too long and scientists are much too impatient to wait on better
breeding to get us where they think we need to be, so they’ve come up
with a couple ways to speed up the process.
The
researchers attempting to create cows for the 21st century include
genetic engineers and genetic editors. Now I know as much about
engineering as a cow does about Christmas, but I was the editor of our
own livestock newspaper so the concept of editors messing around with
the cows genome frightens me. The job of an editor is to correct
mistakes and cut, cut, cut. The space in any periodical is some of the
most valuable real estate in the world and any space an editor can save
goes right to the bottom line, like shortening a 16 page newspaper to a
12 pager. Some editors I’ve had didn’t even read the stories but just
whacked off a chunk at the end that may have contained the punch line.
I’d hate to think that gene editors would follow the same shortcuts in
whacking off key parts of the cow’s DNA so we ended up with cows without
a rumen or missing some limbs.
The
only thing I know about engineers is that they make more money than
editors do and have retirement benefits and health insurance. But as I
understand it, the difference between gene editing and genetic
engineering is that the engineers take germ plasm from an entirely
different animal or plant and insert it into another’s DNA, so you could
end up with sheep that have litters and hogs that go “moo.” Gene
editing, on the other hand, takes advantage of something called
“mutagenesis” which has been going on ever since the first fish walked
out of the sea on its own two gills. Gene editors simply speed up the
process of evolution by “turning on and off” certain genetic switches.
For example, you might say that eventually all beef animals will be
polled, so genetic editors just speed up the process. It’s like
evolution on steroids.
According
to the Center for Food Integrity, gene editing is going to be a “game
changer” and “is in its earliest stages.” Which merely means the gene
editors haven’t got all their lobbyists in place to start paying off
politicians in DC just yet. But they do say it will have big benefits
for the “stakeholders.” I get nervous whenever I hear that word and I
don’t understand how a group playing with our food on the genetic level
can have the word “integrity” in its name.
