In the (proposed) Standard Model of the Mind available at the URL
http://www.scn.org/~mentifex/ AI Minds for Uncontrollable Robots,
a simple mechanism for the evolution of concepts is put forward.

Concepts evolved in three steps.  First, neuronal memory fibers
recorded engrams of frozen moments in the life of the organism.

Second, some neuronal memory fibers on the neural grid separated
from their dedicated sensory input pathway and became free to ab-
stract generic data from specific memory patterns.  This process
allows a central nervous system to become aware of, and react to,
PRIMITIVE patterns frequently encountered in the external world.

Thirdly, the primitive patterns of repetitious perceptions became
building blocks for the orthogonal EXPLOSION of concept-formation
as ever keener and more distinctive classifications resulted from
the attempts of the neural organism to deal with its environment.

A central nervous system CONCEPTUALIZES from two enormous sets of
classifiable data:  raw sensory perception of the external world,
and fundamental CATEGORIES serving as the internal basis of hier-
archies of concepts ranging from primitive to verbal to abstract:
