Tear Dr. Lederberg:

I note in your recent admirable review the
following:"Recent writing has tended to assume the
accidental production of the first living protein
molecule (13,20,139), discounting the improbabilities
with the stipulaticn that life has evolved."

T note that my book,"Time's Arrow and Evolutiont
has been included with reference tc this statement.

Since I have taken some pains to point out the
improbabilities of this I was somewhat stertled by
your statement. Might I suggest a rereading?
