DNA is only a coding system and as such it is necessar to take it, other coding system of great importance is language. in DNA there must be a necessity for MLM multi-level memory, information gained from the “informational environment” of organism must allow for differentiation in importance of such information, this must be expressed in the level at which the information is stored, there must be many levels in DNA as there are many levels of imoportance in brain storage of words, grammmar etc.

Analogy helps to understand, that in turn again requires knowledge in many sciences.

Once more thanks for the post, it is excellent and it supports all my ideas I have had so far.
