Thank you both Paul George;
I always failed math. I think I understand what you said. And I think that describes the one stock model. I wish I knew how to paste picture to the list. But here is a description of the model.
A stock labeled population initial =0.1
An inflow labeled birth= population*r
An outflow labeled death= population^2* r A converter labeled r=1.8 This is in no way representative of much that I know of. But if you run a "comparative graph of population and r (I hope it works)with a sensitivity run of 30 starting r at 1.8, it is very interesting.
I am on my way home to look up a definition of a discrete system versus a continuous system.
The primary point I was trying to make is that innovation occurs all the time, kind of like a mutation, but they only stick if there is a match between it and the characteristics of the context.
