Yockey published 7 articles in the Journal of Theoretical Biology from 1974 - 1995 and was organiser of the Symposium on Information Theory in Biology . The difference between life and matter is information. The 3-D structure of proteins enables specific biochemical reactions to be speeded up. This sustains structures essential to life. In the end information is the difference between life and matter, between biology and physics.
Information is the ultimate explanation of life.
It is fortunate that information theory in mathematics and engineering exists. Yockey uses the theory of communication systems not only as a metaphor, but as a theory to describe, explain and predict phenomena in molecular biology. The information in DNA is transmitted to the information in proteins. DNA is encoded information. Proteins are decoded information.
