Can anyone in the group help me find this
article on the net, or do you know the hypothesis
Black is suggesting?

Here is what I know.

Black, S. 1973 A theory on the origin of life. Adv. in Enzymology
38, 193-234. "Black suggests that some early peptides might have
served as templates for the aggregation of nucleotides that may
have then bonded together to form a precise mold for the replication
of these same peptides. This view has the advantage of offering
a mechanism by which the replication of both peptide chains
and nucleotide chiains would have been interdependent from the
start. Also as one chain lengthens during further evolution, so
does the other, each gradually improving its replicatory role until some of the
pesent features of nucleic acid replication and protein synthesis evolve.
Unfortunately as with naked genes, we still find it difficult to imagine the
spontaneous origin of such a precisely organized nucelic acid template."
Strickberger, Evolution.

Comment:
as to the last concern, I would suggest that the heat cycle
would drive the process thus eliminateing the 'difficult to
imagine' question.
