The biology

The book links three things: bacterial restriction–modification, vertebrate adaptive immunity, and cancer — all systems that identify and destroy what does not belong. Immunity recognises a foreign antigen and acts. Its core is DNA rearrangement — shuffling and altering gene segments to make a multitude of slightly different antibody genes, enough to bind millions of antigens. The response is acquired: weak on first exposure, faster and stronger on the second.

Self and not-self, matched on the address

Antibody diversity is the address rewriting part of itself to recognise the foreign — millions of coordinates generated from a few segments by shuffling. And the recognition is the same operation seen in the bacterium's restriction system (Paper 9) and in anti-cancer surveillance (Paper 23): self versus non-self, matched on the address. One faculty — knowing what belongs to the coordinate and what does not — worn at three scales, from a bacterium's methyl marks to a vertebrate's immune memory.

THE READING
Restriction-modification, adaptive immunity and cancer surveillance are one operation: self/non-self matched on the address. Antibody diversity is the coordinate rewriting itself to know the foreign.

Where this departs from current science

Current science saysThe Force of Time says
Immunity, restriction, and cancer surveillance are three separate systems.They are one address-matching operation — self/non-self read on the coordinate — at three scales.
Antibody diversity is combinatorial gene-segment shuffling.It is the address rewriting part of itself to recognise the foreign.
