Summary of “An overview of evolution and the mind”

3 breakthroughs led to the evolution of the mind:

1) Natural selection
2) Representation plus computation
3) Directed abstract thinking

Paragraph Summary
Of the four Directed abstract thinking made humans exponentially more competitive and gave us unlimited access to the world of imagination
The mind Life began with these precursors arising in a stable location: carbon fixation, power source, RNA world, lipid bubble enclosures (~4 billion years ago)
From this These precursors were enough to initiate and support the evolution of single cell life, and eventually LUCA (last universal common ancestor) (~3.5 billion years ago). Multicellular life and sexual reproduction followed. (~1 billion years ago)
Larger multicellular The value of predictive feedback leads to evolution of brains to provide centralized control of the body (~550 million years ago)
For the most I am going to analyze brain function from the top down logically instead of mechanistically from the bottom up.
To control Animals know in advance where the food will be and move their bodies toward it, but how?
The brain operates Brains collect information from their environment and compute what they should do next
At every The centralized brain must coordinate the body using a single-stream step selector (SSSS) to produce a chain of actions that accomplish goals
While we Animals use consciousness to reason, which is a more flexible approach to control than learned behavior
Brains use The brain uses massive parallel processing for sensing, memory and motor control
The SSSS The SSSS and our entire reasoning capacity is serial but multitasks, though our primary task dominates our awareness
Why wouldn’t Minds uses serial processing to facilitate prioritization and because it works pretty well
The brain controls Brains use association-based and decision-based strategies, but association-based strategies don’t need consciousness or what we think of as intelligence
Reasoning is Reasoning uses both kinds of strategies, but the decision-based ones predominate and include deduction and induction. The mind distinguishes the environment into a objects and reasons with them.
We experience The SSSS as the center of conscious awareness, making us a program running in the brain. Consciousness feels the way it does so that important information grabs our attention.
