SOCIOCULTURAL EVOLUTION
-Gerhard and Jean Lenski
This is a theory of how societies (socio) and cultures (cultural) have
changed throughout the course of
the history of humanity. The Lenskis believe the key driving force behind
this change is technology.
They define technology as including both objects (material culture) and
stores of knowledge and
information (nonmaterial culture). In fact, they believe the two cannot be
separated. The creation of
new objects frees some humans to engage in generating new knowledge which, in
turn, leads to the
creation of new objects which, again, frees more humans to generate more
knowledge, in an ongoing
process. The Lenskis trace how technology has led to the development of, and
changes in, the social
institutions (GREEF), beginning with the earliest human societies and
continuing all the way to the
current era. All societal types can still be found in existence today. They
are as follows:
1) Hunting and Gathering Societies (250,000+ years ago)
The first and longest lasting societies, Hunting and Gathering societies,
were small societies, most bands
of 25-100 people. The main food sources were wild animals and plants. While
some challenge this, most
archaeological evidence to date supports the view that men did the hunting
and women the gathering.
This is thought to be based on biological differences. Men tend to have more
upper body strength,
needed for hurling crudely fashioned weapons. Women generally have greater
lower body strength,
needed for the bending and stooping required for gathering vegetation. Even
today, on average, men
are better at spotting moving objects and women at spotting stationary
objects. Hunting and Gathering
societies were nomadic (constantly moving) because food sources became
depleted as the herds moved
and all the plants in an area had been gathered. Interestingly, these
societies were highly egalitarian
(equal). Since they were nomadic, they didn’t accumulate much property and
food was shared to
ensure survival of the group. The sexes were also quite equal because women
made substantial
contributions to the food supply, usually providing more food/calories than
men (though hunting
provided needed protein). Collective violence was limited; there was no war
as we think of it. Think
back to the definition of a social institution and you will realize that, at
this stage of societal evolution,
all the needs met in modern societies by other institutions were met in
Hunting and Gathering societies
by the family. There was no structured political system and deviance was
controlled informally, one’s
job was learned by “doing”, there were no separate religious positions (in
some cases, shamans claimed
special knowledge of the supernatural but this was not a full-time position),
and traditions and other
knowledge were handed down orally. Therefore, the GREEF for Hunting and
Gathering Societies is as
follows:
G = no
R = no
Ec= no
Ed= no
F= yes; the only social institution, responsible for addressing all basic
social needs
2) Horticultural Societies (~10-12,000 years ago)
Tech advance - the knowledge of planting
crops using hand tools
3) Pastoral Societies (~10-12,000 years ago)
Tech advance - the knowledge of herding,
breeding, and domesticating animals
Horticultural societies and Pastoral societies are two different types of
societies. However, they began
appearing in the same time period and shared some institutional similarities
(enough that, for the
purposes of an introductory course, we will consider their GREEF as one). In
both cases, humans were
developing more sophisticated knowledge (nonmaterial culture) and tools
(material culture). The
technologies may sound primitive to us but they led to dramatic changes in
social life, including growing
to tribes of between 100-2,000+ people. The main determining factor as to
whether a society became
Horticultural or Pastoral was geography. To become horticultural, fertile
soil and a consistently available
water supply to water crops were needed. To become Pastoral, herd animals
that could be
domesticated were necessary. While Pastoralists were still somewhat nomadic,
both types of societies
became semi sedentary, meaning they had temporary settlements. This allowed
for the development
of social surplus – producing enough for your own needs and having some left
over, which changed
society in momentous ways. This surplus led to greater inequality and
disputes as some had more
surplus than others, i.e. a bigger herd or a larger crop, but this surplus
was also traded and bartered for
goods and services, freed some from daily subsistence work so that they could
focus their attention on
creating new knowledge and tools, thus allowing three additional social
institutions to emerge –
government, religion, and economy. The family changed from encompassing the
entire society to a
kinship system based on clan affiliation. Three of the world’s great
religions – Judaism, Islam, and
Christianity - trace their roots to Pastoral societies. Warfare and slavery
across societies, in addition to
trade and diffusion, began to appear. The GREEF for these two types of
societies is as follows:
G = beginning: a full-time tribal leader to make rules and settle disputes
R = beginning: a full-time religious leader to pray (for rain, abundant
crops/herds) and heal
Ec= beginning: barter and trade of social surplus
Ed= no
F = kinship system; clans
4) Agrarian Societies (~6,000 years ago)
Tech advance – animal drawn plow
We often speak about the Industrial Revolution but harnessing animal power
led to the Agrarian
Revolution. One of the most obvious changes was an unprecedented increase in
population size, with
the largest societies swelling to several million people. This was because
the animal plow allowed
humans to produce huge levels of surplus and, very significantly, to create
permanent settlements.
Horticultural and Pastoral techniques quickly use up the nutrients in the
topsoil. The animal drawn plow
turns the soil more deeply. Also, since so much more food can be planted
during the planting season, it
is possible to practice crop rotation and allow fields to lie fallow
(unplanted) for a season while they
regenerate nutrients. This meant that numerous people were freed from the
need to contribute to food
production, so human knowledge and creation of new objects increased at a
rapid pace. Early Agrarian
societies are sometimes referred to as the “dawn of civilization” because, in
a relatively short period,
money, the wheel, mathematics, and writing were invented, leading to “high
culture” in the form of
philosophy, theology, literature, art, architecture, and science. However,
inequality became
pronounced, with up to ¾ of the population of some Agrarian societies
consisting of slaves. The scale of
war also expanded as empires rose and fell. The three institutions that
emerged/began in Horticultural
and Pastoral societies became complete social institutions with multiple
statuses, roles, etc. Writing
allowed for laws and also books, so education began to emerge as a social
institution, although it was
not available to women, commoners, or slaves. Societal size and permanent
settlements once again
changed the nature and composition of the family. The GREEF for Agrarian
societies is as follows:
G = complete: monarchs and their advisors, military, written laws,
governmental buildings
R = complete: religious hierarchy; churches, temples, mosques; books of
religious instruction
Ec= complete: money; many new jobs (shopkeepers, blacksmiths, construction,
etc.)
Ed= beginning: only for an elite few
F = extended, or three generations
5) Industrial Societies (~200 years ago)
Tech advance – machines
Stop and think for a minute: up until a little more than 200 years ago, all
work was done by humans and
animals and yet, now, we take machines for granted in our everyday lives.
Machines radically changed
society. Life expectancy increased dramatically, population exploded, cities
mushroomed, economic
production multiplied, environmental damage increased, and warfare became
much more deadly. The
most important social change of industrialization was the expansion of
education to more and more of
the public until it ultimately became universal (for all). Education became
necessary because people
needed to know how to read and write, add and subtract, etc. to work the
machines. However,
education becoming a complete social institution transformed the other
institutions and had profound
impacts on society. This is because educated people wanted a say in their own
governance, religious
choice, and economic rights. They formed unions and demanded the right to
vote. They moved to the
cities for factory jobs and the family structure changed as people earned
their own wages instead of
remaining on the family farm. Therefore, in early industrialization (before
the expansion of education)
levels of inequality increased whereas this trend later reversed, and
industrial societies became more
equal than what preceded them (Agrarian societies). The GREEF for Industrial
societies is as follows:
G = increasing democracy based on increased voter participation
R = increasing diversity based on increased choice
Ec= large middle class
Ed= complete; public (for all)
F = nuclear, or two generations
6) Postindustrial Societies (~50 years ago)
Tech advance – “Thinking machines”*
*Clearly, machines do not think! The idea is that the machines of the
postindustrial era are qualitatively
different from those of the industrial era. While the industrial machines
were designed to produce
goods (automobiles, toasters, washing machines), the postindustrial machines
are designed to provide
information and services (computers, satellites, lasers, ultrasound, robots).
The Postindustrial societies
are sometimes referred to as ‘knowledge and information’ societies. Work is
increasingly moving from
manufacturing goods to providing services and well paying jobs require high
level s of education and
‘thinking ‘skills. The full transition to Postindustrial societies is likely
to be just as revolutionary as the
Agrarian and Industrial revolutions. While it is the job of sociologists to
analyze this new type of society,
and we are doing so, it is far too early to conclude exactly how it will
change society and the social
institutions (GREEF) over time. For example, if you had told someone in the
early stages of
industrialization that industrial society was characterized by democracy,
public education, and a large
middle class, they would have stared at you and assumed you were from another
planet! Early on, as
previously noted, industrial societies were highly unequal with low wages,
horrible working conditions,
long hours, and young children working alongside their parents in the
factories. As societies became
fully industrialized, these things changed in what most would consider a very
positive direction. So, with
Postindustrial societies, all we can do is study what has occurred thus far,
knowing full well those things
may be modified or drastically altered as time goes on. In terms of equality
of the sexes, it appears the
Postindustrial societies are even more egalitarian than Industrial societies,
which were moving in that
direction. Economically, the initial changes are toward increased inequality
and what sociologists and
others call the Hourglass Economy (see below). Industrial societies, over
time, with child labor laws,
minimum wage laws, worker safety laws, etc., created good middle class jobs
in the manufacturing
sector. The loss of manufacturing jobs, or deindustrialization, is occurring
in Postindustrial societies as
blue collar manufacturing jobs are increasingly performed by robots. An
example is the U.S. steel
industry which has been able to maintain, even increase, steel output but is
highly ‘roboticized’,
requiring fewer workers than ever before. As fewer workers are needed on the
factory floor,
Postindustrial societies are even shedding white collar management jobs in
factories, as fewer managers
are needed for fewer people. This has resulted in “middle class squeeze”.
This means that new job
creation is concentrated in the high and low ends of the hourglass. The jobs
in the high end require high
skill and education levels and receive high pay. The jobs in the low end
require low skill and education
levels and receive low pay. Former manufacturing workers’ skills do not
translate to the high end so, as
their jobs are lost, they tend to fall to the low end, increasing inequality.
Some sociologists, economists,
etc. argue that we are rapidly moving beyond middle class squeeze to ‘job
squeeze’ more generally as
even jobs at the high and low ends can be done by the ‘thinking machines” .
We see this at the low end
as scanners in grocery stores mean fewer cashiers are needed and online
shopping means fewer retail
sales clerk jobs. At the high end, lasers and ultrasound mean fewer surgeons
are needed, robots sorting
and bottling pills for online pharmacies means fewer pharmacists are needed,
and distance education
requires fewer college professors. Do not commit anomic suicide! We talked at
the beginning of the
semester about how hard it is to step outside of your own historical time
period and envision the future,
and it is. However, that doesn’t necessarily mean the future will be bad. All
we know is it will be
different. Now that you’ve gotten a brief history of human societies via
Sociocultural Evolution, ask
yourself, “How long have the majority of people gone to work and been
compensated in the form of
wages”? If you’ve been paying attention, you know that it’s only been about
200 years, since the
Industrial Revolution. So, if it was different throughout human history, it
will be different in the future.
The way we define work and how we are compensated must, and will, change. It
always has. You guys
can discuss possibilities and I’ll be happy to discuss possibilities when I
return.
