Talk:ADAM Discovery

The "double-helix" model of DNA structure was first published in the journal Nature by James D. Watson and Francis Crick in 1953, (X,Y,Z coordinates in 1954[6]) based upon the crucial X-ray diffraction image of DNA labeled as "Photo 51", from Rosalind Franklin in 1952)

Very tight timing there (for the soon following Plasmid developments with their significant genetic modifications - to have widespread commercial use in Rapture by 1959). It is possible that scientists in Rapture had discovered this earlier,  so that Tenenbaum could be familiar with it. Alot of the further understanding of nucleotides and base-pairs came in the following decades on the Surface (rather alot for the few genetic specialists in Rapture to have come up with).
