Hypertext book explores coevolution and revolutions
in human cognition and cognitive technologies leading
to the emergence of modern knowledge-based sociotechnical organizations as living entities
Last episode explains how coevolution of cognition
and technologies enabled forest-dwelling apes to
become “human” and dominate the entire planet in
something like 4 my.

Genes & memes – genetic vs cultural adaptation

Genes
–
–
Determine individual anatomical, physiological and neurological
capacities
Mutation: physical change to one or more DNA nucleotides on a
chromosome



12
Change is slow multi-generational process depending on natural selection
Movement rather than increased versatility
Meme = unit of culture (an idea or value or pattern of behavior or
knowledge) that may be passed between individuals or from one
generation to another by non-genetic means
– Change often intra-generational depending on innovation, social
relationships and processes
– Transmission limited by genetic capacity to communicate detailed
information
– Essential information easily lost or corrupted over generations.
– Rate and extent of cultural accumulation depend on genetic capacity,
group size, (culturally transmitted) cultural practices
Adaptation = application of genetic or cultural
knowledge to solve problems of life


Natural selection on genes works at the level of
individual genetic variation depending on successes of
carriers of particular genes in the population
Selection on cultural knowledge works at the level of
culturally variant groups, depending on successes of
the different groups.
–


13
A group whose shared cultural knowledge allows it to solve
problems other groups can’t solve grows at the expense of those
other groups
Successful items of cultural knowledge may be carried by
individuals between groups to speed the evolutionary arms race
Rate of cultural evolution depends on individuals’
genetically determined capacities to understand,
remember, and transmit cultural knowledge

Mutation is blind
Natural selection tracks current requirements, generally with continuing
specialization

Retain original adaptation together with adding new capabilities, i.e.,
accumulation or (very rare) cases of gene duplication and functional divergence
New mutation crosses adaptive threshold opening new adaptive landscape (i.e.,
grade shift)

Socially foraging, tool-using forest apes in East
African Rift Valley 5 mya

Increasing need to retain and transfer cultural knowledge
Pressure to increase brain capacity: increased fine motor skills, social
learning, more cohesive and cooperative group dynamics
Cooperative defense and scavenging of carnivore kills cached in trees
gave early hominins increased access to meat on the savanna


Savanna offers limited resource of edible plant foods but
a rich supply of grass-eating herbivore meat

Fast (intragenerational)
Cultural knowledge pertains to group only (→ group selection)
Group knowledge easily lost (depending on genetically determined capacities,
group size, structure, and dynamics)
Culturally transmitted tool using/making knowledge was grade-shifting
Savanna ape inherited limited capacity to transmit cultural knowledge
and existing culture of simple tool-making and use from CLCA

22
Hominin teeth can’t tear skin
and flesh of large prey
Anvils & hammer stones used to
access marrow from scavenged
carcasses
Kanzi the bonobo learned to
break stones & use flakes as cutting tools
Early hominin culture assimilates knowledge that broken hammer stones
can be used to cut skin & ligaments for butchering large prey before
lost to competing carnivores and scavengers
Suggests neural/social/linguistic capacity to accumulate knowledge
of complex technologies was stringently limited for most of hominin
history
By 3 to 2 mya hominin competition and dominance of other carnivores
begins to reduce overall carnivore diversity in E. Africa

3 mya aggressive scavenging of kills
reducing food supply for some
carnivores causing local extinctions.
2 mya active hunting of large mammal
prey using spears + Oldowan butchering
tools further reduces carnivore
resources.
1.8 mya hominins in Olduvai Gorge were top
carnivores selectively hunting prime quality bovid prey (Bunn & Pickering
2010; Bunn & Gurtov 2013).
By 1.8 mya carnivorous hominins extended to Dmanisi, Georgia (Hemmer
et al. 2011; Carrion et al. 2011), and from there quickly spread across
Asia and into Europe (as H. erectus)

Bounded (groups separated socially by cultural differences and breeding systems)
Complex (groups formed by multiple individuals playing different roles in group)
Mechanistic (interactions of group individuals determine group functions & activities)
Self-referential (group identity determined by culturally transmitted knowledge)
Self-producing (group retains its continuity beyond the lifetimes of single individuals
through individual reproduction and recruitment combined with indoctrination in and
transmission of accumulated cultural knowledge from one generation to the next)
Autonomous (group manages its own survival and continuity through knowledge-based
interactions of its individual members)
Autopoietic entities represent units of selection
Pre-linguistic groups probably qualified as autopoietic – but group identity and
adaptive variation greatly strengthened by language-assisted cultural accumulation
What enabled increasing tool complexity?



Development of increasingly complex
stone tools (Stout 2011) correlates
with larger brain capacity and
language development.
Even with language, knowledge is
limited by what can be learned,
remembered, and passed on by
single individuals.
By < 500 kya, pace of change in the
capacity to deal with multiple
complexities is too fast for genetic
adaptation
< 50 kya increasing rate of change
suggests major innovation to support
accumulation of much larger volumes
of knowledge.

“All modern human populations have
language, and there is no difference in
language capacity between living human
populations. Parsimony implies that the
most recent common ancestor of all
modern humans had language, and had
all the biological prerequisites for
language” (Johansson 2013).
The common distribution of language
proxies across human and neanderthals
in genomic, paleoanthropological, and
paleoarcheological contexts show that
human, Denisovan and Neanderthal
common ancestor had a capacity for
modern language, speech and culture

Techniques - think memorably: express knowledge in rhythm and rhyme
with common formulas and phrases, link breathing and gesture, act out,
associate with song and dance, organize by intrinsic logic, etc.
–

Primary sources for understanding mental techniques used in primary
oral cultures to accurately memorize and recall large and complex
bodies of information:
May increase individual memory capacity by 10 to 100-fold or more
Use at group level to preserve and transmit cultural knowledge
Cultural capacity depends on group size – larger groups allow formation
of subgroups (i.e., “guilds”) to manage specialized bodies of knowledge
Method of Loci builds on the natural rhythms and progression of
life

Memorable events happen in time and space (specific locus in 3D space)
–
–

Songlines:
–
–

hunter gatherers learned to consciously index geographic, resource & natural
history knowledge against tracks in the existing landscape where it is relevant.
Other knowledge may be indexed against loci on other shared lines (e.g., stars in
the night sky) or with stories associated with landscape features, etc
Method of loci uses an ordered sequence of memorable loci as indexing
points along existing or imagined space-time lines
–
–
–
35
Innate way to organize memory probably common to all “intelligent” animals
Focus on the space-time locus to retrieve memories of circumstances and events
that happened at that locus
–
–
Associates memorably expressed snippets of knowledge with particular loci in
the line
Other mnemonic techniques make snippets memorable (e.g., imagery, rhythm,
rhyme, oration, song, dance)
Group rehearsal and repetition strengthens memory traces
Group sharing adds redundancy and corrects errors in individual memory
In larger populations subgroups can maintain specialized knowledge
Becoming settled – surmounting the knowledge
capacity of nomadic life in the post-glacial era





Nomads limited to technology they can carry or fabricate on demand
Accumulating technological knowledge enables more effective use of
smaller geographic areas – larger populations accumulate more knowledge
Becomes practical to establish core living areas with permanent goods &
structures (e.g., specialized tools, houses, and structures for cultural
activities and processing and storage of food and other property)
Reduced contact with tracks in the broad landscape combined with need
to manage more and more specialized knowledge of technology drives
development of new and archeologically significant mnemonic systems
Solution: When songlines no longer suffice, build compact monumental
landscapes that can be traversed sequentially (Kelly 2012 - e.g.,
Stonehenge, Poverty Point, Chaco Canyon Kivas, etc.)

Current Anthropology 52(S4), Wenner-Gren Symposium: “The Origins of
Agriculture: New Data, New Ideas” (October 2011) reviews in detail the
archeological record of cultural & demographic transitions from nomadic
hunting & gathering to formation of agricultural towns
With settlement, nomadic groups become territorial villages

Positive feedback drives ever-increasing growth rate of cultural
knowledge accumulation for ever-increasing ecological hegemony over
environmental resources

The autopoietic entity becomes a socio-technical construct comprised of
people, their linguistically mediated communication networks, their knowledge,
their technologies and their built environment
Accumulating cultural knowledge enables more efficient/effective control of
local resources
Surplus resources enables population growth in turn providing more capacity
for cultural memory
Development of ever more sophisticated mnemonic devices
Population growth enables more specialization of crafts, trades and guilds able
to accumulate still more varied and detailed knowledge of the world
Ecological grade shifts result in demographic transitions
increasing socio-cultural/economic complexity

Mobile hunter-gatherers (~15 – 20 adults in group – say 2-4 families)

Part-time tool-makers & apprentices (specific resource and processes knowledge)
Organized hunting parties

Gatherers use specialized geographic & natural history knowledge to find resources
Temporary shelter construction, child-care, fire tending, food processing
Extended networks for additional mating opportunities, knowledge exchange & barter
Settled foragers (~ 40 adults in community – say 8 families)

Specialized tools that can be kept on hand, perhaps leading to full-time specialization
Wide ranging hunting parties transport butchered products back to home-base
Locally intensive gathering and harvesting with processing and storage
Construction & maintenance of permanent shelters & specialized structures
Need to protect valuable “capital” (community / personal ”property”)
“Tribal” networks & mnemonic systems for preserving & exchanging knowledge

Leader/organizers + possibly specialized team members
Geographic & natural history knowledge target prey and dangers
Skinning, butchering, processing
Production of specialized goods and surplus resources encourages formal barter economy
Social norms and knowledge specialties common to interrelated communities (“tribe”)
Development of specialized “cultic” sites on neutral territory for rehearsal, standardization, and sharing of
various bodies of knowledge
The Agricultural Revolution extending human control over animal
and plant metabolism

Major techno-ecological transitions
–


Demographic revolution – egalitarian communities become hierarchically organized tribal regions
and towns (encompassing dozens to hundreds of families)


Hunting → herding & corralling → husbandry, dairying, cheese-making, tanning, animal power & transport
Harvesting, storage, milling, baking & brewing → planting → tilling & irrigating → hydraulic engineering
Stone & mud construction → brick making & firing → ceramics, pottery & metallurgy → structural engineering
Population growth and technological innovation leads to proliferating specialization & restriction of life roles:
farmers, pastoralists, despots, leaders, warriors, administrators, traders, priests & healers, educators, masons,
artisans (e.g., tool-makers, potters, tanners, bakers, candlestick-makers, smiths, armorers), etc.
Specializations dependent on knowledge passed down via family specialization, confraternities, and guilds
Management of surpluses, specialized production, and trading leads to development of formal economies and
despotic/priestly states
Revolutionary emergence of new mnemonic and knowledge management technologies to release
cognitive demands for memorization for thinking and doing
