Associative Learning: Connecting Sense and Action
Associative learning is the expansion of behavioral triggers, demonstrated by Pavlov’s classical experiments with dogs.
Bacterial Chemotaxis as Primitive Learning
Single-cell bacteria demonstrate primitive learning through chemotaxis behavior searching for food sources.
Behavior as Goal-Directed Search
All learning systems from bacteria to AI engage in goal-directed search for effective behaviors.
DNA as Learning Information Storage
DNA stores the accumulated learning of evolutionary processes as genetic information in all living organisms.
Evolutionary Learning as First Layer
All life participates in evolutionary learning, the first and slowest layer of natural intelligence.
Genes to Proteins: Molecular Machinery
Genes (specific DNA sequences) are transformed into proteins that create organism form and function.
Habituation: Learning to Ignore
Even simple organisms including plants demonstrate habituation, the most basic form of learning.
Human Brain Expansion: The Notch2NL Gene Mutation
Around 3 million years ago, a mutation occurred in hominin DNA activating the Notch2NL gene.
Language as Abstract Intelligence Marker
Humans developed complex sequential language, distinguishing our communication from animal signaling.
Learning as the Core Engine of Intelligence
Modern AI researchers define intelligence through capacity for learning rather than accumulated knowledge.
Learning Machines vs Programmed Machines
Modern AI researchers shifted from rule-based to learning-based approaches during the late 20th and early 21st centuries.
Neural Learning: Lifetime Adaptation
Multicellular organisms evolved brains as the second layer of learning, enabling adaptation within individual lifetimes.
Play as Consequence-Free Learning
Many animal species, especially mammals, engage in play behavior to accelerate learning.
Reinforcement Learning: Trial and Error
Animals from birds to rats to octopuses learn through trial and error, testing behaviors and retaining successful ones.
Slime Mold Distributed Intelligence
Researchers tested slime molds by exposing them to food locations mirroring Tokyo railway station positions.
Symbolic AI vs Learning-First AI
AI researchers transitioned from classical symbolic approaches to modern learning-first paradigms.
