Nature design based on stochastic

Nature design based on stochastic
It means you dedign a structure and left nature to test. If it work it work.
But the invent of neuron free bio system of use it life to test.
It can sense the world and change itself.
First it is the environment
Then it is communication between species
Then it is sense(predict) over time.
So sensr of time is a big step.
Then we need to remember stuf at different time
Memory become important.
When the system became complex
The last will be sense of itself.
