Another way of visualizing the genetic intelligence of an organism, say human. With the exceptions mentioned earlier in this thread, each of the 10^14 cells in the human body has the same DNA content. From a functional point of view, we can think of a single set of DNA memory controlling 10^14 parallel processors. Each of these processors has it's own set of I/O channels representing the information exchange across a single nuclear membrane, hormones coming in, mRNA going out (as well as other molecules I don't know about). The intelligence lies between the nuclear input and the nuclear output and is under genetic control. It may be that the computing power per cell can be thought of as being somewhat less than 3 x 10^5 instructions per second, once we allow for redundancy. In total however, the 10^14 parallel processors represent a heck of a lot of data processing. The next argument coming down the pike will be the redundancy of identical cells in a given type of tissue. I'll counter in advance. Even if all cells in the body were identical, each is under individual control, resolution counts for something. 10^14 pixels would make a pretty high resolution computer monitor, and it would take quite a computer to generate a animated picture with that much resolution. __ Ken Easlon ken@holonet.net
