Nicholas Humphrey- How did consctiousness  evolve?

Dec21, 2023: 

In his brain model - stimuli arrive causing reflex behaviour. There are adaptive benefits to monitor and direct behavior. There are adaptive benefits to simulating the stimulus followed by  behavior, followed by evaluation of outcome, followed by simulating modified behavior to change outcome.

This feedback loop, Nicholas Humphrey claims, manifests consciousness.

I don't agree. There are man made machines that have adaptive controls. Imagine adaptive computer programs that can designed. When a problem does not yield to available analytics, the program may be designed to simulate a state, inputs and outputs. Then evaluate the output against requirements. If not goof it, resimulate changing the controllable variables. The machine is not conscious and we did not hit the necessity of consciousness to produce such machines.

Nicholas Humphrey uses the term attractor to mean what I call objective towards improved being.

Consciousness is not necessary for survival of organisms.

Perhaps conscious beings gain an evolutionary advantage by being interested in well being as in they become interested in avoiding pain (harm). Can an organism be interested in avoiding harm without being conscious. Can it not arrive at the same goals by internal representations of the world and computations on the representation?
