...protein, and make it become the norm for the species, takes, on the average, six million years. What we're being faced with now is the possibility not only of changing one amino acid in a protein, but of producing whole new proteins overnight across very distant boundaries. Professor Meselson just conveyed to you the idea that it happens all the time, that it's very natural--we're just speeding up a natural process. That's a lot of speeding up. One amino acid change has taken 20 million years in cytachrome...
...guidelines, which state, "At present the hazards may be guessed at, speculated about, or voted on, but they can not be known absolutely in the absence of firm experimental data, and unfortunately, the needed data were more often than not unavailable. As a scientist and a colleague of Matt Meselson's, I am as anxious as he to have these fundamental questions in biology answered, but as I said before, the problem is how one is going to go about answering them...
...Meselson said scientists would not be creating whole new species, just individual new organisms. He said that those organisms would have to face "a competitive struggle for every available ecological niche...
...Meselson said that in the last 50 years no one who was not connected with a laboratory had been infected by research organisms...
...Meselson said he was "fully sympathetic" with the extension. "I have no objections to the Review Board taking a reasonable amount of time to study the problem...
