'GROK: How Did Consciousness Evolve?'
###GROK: How Did Consciousness Evolve?
##Goal
I read biology/psychology related stuff to keep up with human behavior from a science perspective - it is useful for:
- creative fodder for sci-fi
- looking for tech angles on culture and mental health
- finding paradigms to create characters/models for story building
That being said, my goals in those areas are loose - a tighter one for this piece would be: think about the consciousness of a fictional character - how developed can it be?

Concept: Evolution as the grand unifying theory of biology
Consciousness’s history of understanding has been primarily: philosophy, cognitive science, religion
What is the adaptive value of consciousness? When did it evolve, what animals have it?
####Concept: Attention Schema Theory
- less than 5 years old
- states: the brain evolved increasingly sophisticated mechanisms for deeply processing a few select signals at the expense of others, and consciouness is the ultimate result of that evolution
####Selective Signal Enhancement
- computing trick: competition
- nerves shout for attention, only a few are heard
- SSE: 700-600 million years ago
- arthropod eye - selects visual edges, supresses the rest
- primitive - doesn’t require a central brain, easily decentralized
####Tectum
- “roof” in latin
- central controller for coordinating senses
- coordinates overt attention
- all vertebrates have one
- constructs internal model for predictions and planning of movement and input
####Wulst
- brain structure, ~350-300 million years ago, reptiles, birds, mammals
- in humans - became cerebral cortex - is massive, by far largest structure in human brain
- reptiles, probably smarter than we give them credit for
####Cortex
- upgraded tectum
- can react variably to variable input (look toward, look away, store in memory, etc.)
Tectum is master of overt attention; cortex adds ‘covert attention’ - moves deep processing from one item to another
The cortex constructs it’s own internal model
- a very abstract set of info for what covert attention is doing, and what it’s consequences are (i.e. machine learning)
####Opportunism
- Teddy Roosevelt: “Do what you can, with what you have, where you are”
- open minded, optimistic
####Social prediction
- one’s self model beocmes a model used to guess at others
Concept: Theory of Mind
- ability to understand the contents of another’s mind
- humans, apes, dogs, crows, crocs (care for their young)
####Language
- a big leap, at least 70k years ago
####Evolutionarily
- we’re hyper tuned to tap into eachother’s mind states - that’s our adaptive edge
- Side effects: False postivies: Ghosts
- [Religion as a healthy, encouraged false-positive for consciousness?]
