... adaptation has been achieved by the process, already mentioned, which hinges on the gaining of information by means of genetic change and natural selection, as well as on the storing of knowledge in the code of the chain molecules in the genome.

Summary: This paper and the corresponding Evj computer program show how information, measured in bits as Claude Shannon did, appears in DNA by Charles Darwin's natural selection. |

Author:
Molecular Information Theory: From Clinical Applications To Binding
Abstract:
Information theory was introduced by Claude Shannon in 1948 to precisely characterize data flows in communications systems. The same mathematics can also be fruitfully applied to molecular biology problems. We start with the problem of understanding how proteins interact with DNA at specific sequences called binding sites. Information theory allows us to make an average picture of the binding sites and this can be shown with a computer graphic called a sequence logo (https://alum.mit.edu/www/toms/glossary.html#sequence_logo).
Sequence logos show how strongly parts of a binding site are conserved in bits of information. They have been used to study a variety of genetic control systems. More recently the same mathematics has been used to look at individual binding sites using another computer graphic called a sequence walker (https://alum.mit.edu/www/toms/glossary.html#sequence_walker). Sequence walkers are being used to predict whether changes in human genes cause mutations or are neutral polymorphisms. It may be possible to predict the degree of colon cancer by this method.
How do genetic systems gain information by evolutionary processes? Information theory was used to observe information gain in the binding sites for an artificial `protein' in a computer model of evolution. The model begins with zero information and, as in naturally occurring genetic systems, the information measured in the fully evolved binding sites is close to that needed to locate the sites in the genome. The transition is rapid, demonstrating that information gain can occur by punctuated equilibrium. (https://alum.mit.edu/www/toms/paper/ev).

are necessary and sufficient for information gain to occur. This process is called evolution. |

If you need background information about information theory you can explore my web site. You may find these two resources particularly useful:
The Ev program was written in Pascal, which is a good language for which there is an open source compiler. However, Pascal compilers are not often set up on computers, so this limits experimentation with Ev to the few people willing to download a Pascal compiler and to set up Ev. In contrast, an open source version of Ev written in Java and available from Source Forge could be used in schools all across the world to help educate students in the precise mechanisms of evolution. Paul C. Anagnostopoulos wrote the current Java version, but there is more to do. If you are interested in joining this effort, please contact me. |

Intelligent Design Creationism and Its Critics: Philosophical, Theological, and Scientific Perspectives Robert T. Pennock, Ed. MIT Press, Cambridge, MA, 2001. 825 pp. $110, ISBN 0-262-16204-0. Paper, $45, ISBN 0-262-66124-1. This book contains both creationist writings and very strong rebuttals to those writings. The errors and deceptions of the creationists are laid bare. I strongly recommend this book for anyone who feels swayed by the creationists and for scientists who would like to see the majority of the arguments and facts against their position.
