Of Hubert P. Yockey - Journal of Theoretical Biology / Cambridge University Press
The rigorous application of Claude Shannon's mathematical information theory to the study of biological macromolecules, formalized by biophysicist Hubert P. Yockey, demonstrates that the human and cellular genome constitutes a literal, not metaphorical, semantic and symbolic structure. Yockey demonstrates algebraically that there is no law of physics or chemistry that can explain the origin of a symbolic code, since the chemical letters of DNA (nucleotides) do not have intrinsic physicochemical affinity for the amino acids they represent in protein synthesis. The genetic code is a conventional system of semantic abstraction independent of the material substrate, demonstrating incontrovertibly that purely mechanistic and chemical causes are incompetent to generate specific meaningful information.
Editorial rereading
Hubert P. Yockey's biophysical treatise introduces the unquestionable discipline of information theory into the heart of molecular biology, forever closing the door on the primitive evolutionary myth of the spontaneous generation of the genetic code by chemical accidents in a 'primordial soup'. For decades, positivist literature insisted on the pedagogical lie that with enough time and electrical rays, dead organic molecules would inevitably self-organize to produce life. Yockey mathematically demonstrates why such a claim violates the most basic laws of communication and mathematical physics.
The epistemic key to the analysis lies in the insurmountable distinction between 'chemical reaction' and 'symbolic information'. Chemical molecules blindly obey electrostatic affinity, but the nitrogenous bases of DNA do not join together randomly or by chemical obligation to encode proteins; They function like a conventional alphabet where the sequence of symbols carries a semantics that is irreducible to the physics of the molecule itself, in the same way that the meaning of the pages of a Cervantes book is not found in the chemical properties of the black ink or the paper of the book. No experiment in the history of the scientific method has observed that the physical-chemical laws of inert matter generate by themselves a semantic and functional symbolic vocabulary.
This mathematical truth completely destroys the anthropological foundation of atheistic materialism. If all verifiable semantic information inescapably comes from an intellectual agent—from a mind—then the molecular code that resides in each cell nucleus is forensic proof that human life was thought, written, and loved by a transcendent Author. In a world where ideological propaganda tries to convince youth of existential absurdity and moral nihilism, the biophysics of DNA raises its voice to proclaim that each human person bears the indelible signature of the God of life inscribed in his or her own biology.
