It is widely talked that the information for building an organism is encoded all in the genome and so people are all investigating how to extract this information.

Actually, it turns out that the DNA encoding of the information depends strong on the physical and chemical properties of the proteins and other chemicals. without study of these properties and without understanging how they affect development, there is no way to understand how could the huge information for building organisms can be encoded in DNA directly.

One analog occurs in human face encoding in computer science.
Question: how can you represent a human face image with 1000,000 pixels with 10 integers and still capture the main features? Impossible?

???
eigenface method: building a set of 10 different standard faces as the base faces similar to basis funciton of Fourier Series, and then use those base function to build a face with different weight on each face. then you got a very close approximatation!

So the idea is that It is the exploitation of the common physical properties of proteins that enable DNA to do extremely efficient encoding!

The ISCID Forums are aimed at generating insight into the nature of complex systems (e.g. biological complexity, organizational complexity, etc.) and the ontological status of purpose, especially from the vantage point of various information- and design-theoretic models.
