Creating Civilization




Neolithic Revolution

A. Revolution--or Evolution?


1. Invention of farming--is something of a misnomer. People did not “invent” farming, because they did not make a conscious decision between food production and hunting/gathering. People began simply to adopt (or not adopt) food production for certain foods, while retaining the option to hunt or gather other foods

2. Creating the surplus--farming becomes attractive because domesticated plants prove to be a fairly reliable source of food; so much so, that farmers are actually able to produce more than they need to subsist--and therefore producing a surplus, which they can then trade for other goods.

B. Why farming wins out


1. Changes in climate--in certain areas meant that gathering food enough to survive on became more difficult, and made raising food a more attractive option (the Fertile Crescent, for example, became more arid, and people living there were forced to begin raising food--both grain and animals--in order to remain there).

2. Changes in Technology--the ability to store a harvest (whether from raising food or gathering it) led people to become more sedentary (it is, after all, difficult to transport a granary to support a nomadic lifestyle). Using domesticated animals to iron-tipped plows also made farming more bountiful as well, and freed up labor from plowing to undertake other duties.


3. Sedentary lifestyle--promoted by the rise of farming led to more children being born. Nomadic peoples tended not to have more children at one time than they were able to carry; with farming families remaining in one location, children were born closer in age in many families, which caused the population of farming groups to grow faster than their nomadic cousins.

4. Productivity of farming--even though food producers were often less well-nourished than their nomadic counterparts, the greater populations of sedentary groups meant that they often prevailed in conflicts between the two groups (that later changes as nomads develop horsey skills and become more mobile).

I. The Development of “Civilization”--the term has become somewhat controversial; here we will adopt Harman’s use of the word, meaning urban settlement.

1. Production of the surplus--people were able to live in cities because with Agri-Culture, the production of food beyong the needs of immediate subsistence--surplus food--became the norm. This allowed people to regularly engage in other activities rather than working to ensure their own subsistence. People began to specialize in various artisnal crafts at this point.

II. Control of the surplus--living in urban areas meant living in groups larger than one’s extended kin network (which was the usual bond between people in paleolithic bands). This led to less reliance upon cooperation, and greater emphasis being placed on coercion to control surplus food production.

A. Armed force--professional soldiers were developed along with urban living areas because they could be used to appropriate surplus food supplies, both from within people within their settlement as well as without

B. Accounting for the surplus--with the development of the surplus there also developed a need to account for it--to be able to tell where the surplus went, to whom--and eventually at what cost. The need for this accounting system led to the development of both a system of writing (for record keeping), and the development of mathematics (for the actual accounting).

C. Rulers and priests--with the development of agriculture, it became important to also keep track of the seasons, and to be able to read (or, even better, influence) the portents so that it could be determined the best time to plant. Among many peoples, the development of a priestly class reinforced the emergence of a ruling class, who emerged because they were able to claim the favor of a particular deity.

1. Early sedentary farming communities were established without class divisions on fertile soil, but as the communities expanded to less fertile soil, improvements to the land (irrigation, etc.) were made. Those making the improvements needed to expand agricultural production, and felt justified in controlling access to these improvements and to exercising control over the surplus produced.

2. In this way, in some areas of the world, community leadership grew to expect tribute to be offered to them (usually in goods)

3. As the means of production changed during the neolithic era, the relationship of people to the means of production changed as well. People tended to accept these changes because of the gradual nature in which they took place, and because the abundance of food during peak periods made the increasingly authoritarian nature of rulers more palatable.



III. Egyptian Civilization

A. Pyramids and Monuments--when we think of Egypt today, we still think of it as the land of pyramids and monuments like the Great Sphinx. But for what purpose were those structures built? To impress onlookers (present and future) of the power and longevity of the ruling class in Egypt--although the monuments outlived the rulers.

1. When the great pyramid/monument building binge took place, Egypt was still on the cusp between the Paleolithic and Neolithic ages; although workers on the monuments worked with iron and bronze tools, the people supplying the food to access to those kinds of tools.


2. The sheer scale of exploitation of the mass population--an exploitation that grew in direct proportion to the growth in the magnificence of the temples, palaces, tombs, and ruling-class lifestyles. This led to the stagnation of the means of providing a livelihood for the greater part of society. That section of society that had been freed from daily toil in the fields no longer had any interest in furthering humanity’s control over nature.

3. With much of the surplus being spent on monuments to their own greatness, spending on infrastructure suffered; as a result, when crops failed due to famine, flood, climate change, insect infestation (see Moses, Bible), leaders in Egypt saw the surplus vanish, and their civilization crumble; this process has been repeated numerous times in history.

B. Technology and Urban Development--the next “great civilizations” to emerge occurred in areas less fertile than the Nile Valley, and had to promote the development of technology in order to produce a sufficient surplus.



IV. Ancient India

A. Aryan invaders--the Aryan people originated in the Caucus Mountains, and invaded India about 1500 BCE


B. Vedic Religion (evolved into the Hindu religion)

1. Ritual centered on the sacrifice of animals--including cattle--and long sagas extolling the exploits of warrior gods

a) This practice of worshipping warrior gods made the expropriation of food belonging to non-warriors more palatable; bulk of goods went to warriors and their brahmin allies.

C. Iron technology

1. Iron implements--the development of the iron axe and the iron-tipped plow made it possible to clear the jungles along the Ganges River and plow the heavy soil of the Deccan Plain, and to make a nomadic people who relied upon raising cattle for beef to begin to rely upon those cattle to pull plows.

2. From Vedic to Hindu--Vedic practives of eating beef became taboo, because the elites relied upon the production of surplus grain as their main source of wealth; therefore, farming peasants had to be discouraged from eating their cattle at all costs.

3. Indian caste system--Aryans had brought with them an ideology that set up a rigid class structure that justified expropriation of the surplus; in the emerging agricultural society solidified into a four-tiered class system, or varna.

a) Brahmin--the priestly caste

b) kshtriyas--warriors and rulers

c) vaishyas--landowners and merchants

d) shudras--artisans and toilers

Fluidity of system--this caste system remained somewhat fluid, although as more castes were added to the system, it became more rigid

Out of Africa: The Human Diaspora

Paleolithic Age



A. Descent from gorillas—man’s closest relatives in the animal kingdom are three members of the ape family: the modern gorilla, the chimpanzee, and the bonobo (aka pygmy chimp)



B. Early humans—about 7 million years ago (or 5 to 9 million years ago), a population of apes in Africa broke up into several populations: the gorilla, the two species of chimpanzee, and the group that eventually evolved into humans.


1. Australopithecus africanas—inhabited the earth between 2-3 million years ago; characterized by a larger brain than simian counterparts. Began the use of crude stone tools (which some apes use, as well)


2. Homo habilis—is thought to have lived between 2.5 and 1.6 million years ago. Homo habilis is the least human-like of the early humans, and its cranial capacity was about half that of modern humans.



3. Homo erectus—believed to be the first true human to venture out of Africa; fossils from Homo erectus were discovered in Asia (on the island of Java—aka Java Man), and date from about 1.8 million years ago. Scientists recently have argued that Homo habilis and Homo erectus share a common ancestor (a kind of “missing link”), rather than erectus evolving from habilis


C. Homo sapiens—generally recognized as the earliest man. Still had smaller brains than modern humans, still relied upon the use of crude stone tools, and their migration pattern still relied upon those areas that they could walk to

D. Homo neanderthalensis—the world Neanderthal is commonly used today as a put-down for behavior we find crude or offensive (or to sell us insurance), but Neanderthal man himself actually had a larger brain than modern man. Neanderthal man populated much of Europe and western Asia, and are the first humans we have evidence of caring for their sick and burying their dead.


E. “The Great Leap Forward”

1. East African sites—Homo sapiens begin using standardized stone tools (meaning several tools of similar manufacture and apparently used for similar purposes), as well as the first jewelry (ostrich shell beads) about 50,000 years ago.


2. Near East (the so-called “Fertile Crescent”) experienced similar developments about 40,000 years ago, which implies that these two areas were in contact with one another (an early trade network)



3. Cro-Magnon man—first to begin to use more complex tools, and material other than stone


a. Bones—bone can be shaped into specific types of tools like fish hooks, needles, and awls, which allowed Cro-Magnon man to expand and diversify their diet, and led to the manufacture of clothing, which permitted these people to better withstand colder climates


b. Also manufactured weapons like harpoons, spear throwers, and eventually the bow and arrow, which allowed them to more safely hunt and kill larger, more dangerous animals—and increase their caloric intake, as well. Neanderthals had been susceptible to broken bones, thought to have been caused by having to wrestle down the larger animals.


b. Developed artwork—Cro-Magnon people were among the first to produce works of art; the best known example is Lascaux Cave in southwestern France



c. Cro-Magnon people in Europe seem to have fairly quickly replaced the Neanderthal people living there previously; whether this was by conquest, or by inter-breeding and assimilation scientists cannot say definitively.


F. Early colonization

1. The Ice Ages—over various millennia, the amount of ice on the earth has waxed and waned (this is one of the arguments used by global warming denialists to argue against human causes for global warming). During periods of glacialization, a great deal of water was locked up as ice, dropping ocean levels significantly, and allowing some early peoples to migrate to areas that previously had been islands (and would return to being islands when that particular ice age ended). It also eventually allowed early humans to cross the Bering Strait, separating Asia from North America, as recently as 10,000 years ago.

b. “Virgin” hunting grounds—these peoples found plentiful game, which the probably quickly hunted into extinction, since their new technology greatly increased the killing capability of humans, and the animals had developed no fear of humans to this point; at any rate, large numbers of large mammals die off as these new people begin to share the continent with them (does this lead to the creation of the belief that man should live in harmony with nature? Quite possibly).


II. Paleolithic societies

A. Foraging societies—all early Paleolithic societies were foraging societies—that is, hunters/gatherers. Since hunting was very much a hit or miss proposition (and still mostly miss at this point, before the development of accurate spear throwing and the bow and arrow), and most of the diet of these peoples was reliant upon the grains, fruit, roots, and shoots that the gatherers were able to find.

Gender-based societal roles—at this early point, hunting was already a male occupation, while gathering the other food was largely the domain of females; however, because most of the band was reliant upon the food gathered for their day-to-day sustenance, this was not a low status occupation.

1. Gathering was a way not only for women to gain status in the band, but also fostered bonds to feed all the members of the band.

2. Hunting—although the luck of hunters was much more hit and miss, meat from the hunt was still highly sought after; hunting itself was an act of cooperation among all of the hunters, because these groups were most successful in frightening an animal to fun off a cliff or into a snare they laid, rather than relying upon one or two superior hunters to kill of prey.

3. Cooperation between members of the band made their survival possible (“From each according to his abilities, to each according to his needs”).


III. Neolithic Revolution

A. Revolution?—or Evolution?—the ‘invention” of farming is really a misnomer. People did not just “invent” farming, because they did not chose to simply begin to cultivate and domesticate certain plants; these things happened gradually over the years, as people chose to cultivate some plants, not others, and still venture forth to gather other foods to supplement their diets. People gradually changed their food procurement processes.


B. Why farming eventually wins out (in most of the world)


1. Changes in climate—in certain areas meant that gathering food necessary for subsistence became increasingly more difficult, and therefore made sedentary farming a more attractive option.


2. Changes in technology—the ability to store a harvest (whether from raising the food by cultivation or by foraging) led people to become more sedentary, since it was difficult to carry large granaries from place to place.


3. Sedentary lifestyle leads to greater population growth—nomadic peoples tend to space children so that they only had to carry one child at a time when they were on the move; living a more sedentary lifestyle led people to begin to have children closer together, and in greater numbers than previously. The move to farming is an example of an autocatalytic process—one that catalylizes itself in a positive feedback cycle, and going faster once it started. This growth in population was larger than could be sustained by hunter/gatherer societies (and, in fact, was often even faster than farming societies could sustain; surprisingly, hunter gatherer groups usually had a higher caloric intake that did farming societies.


C. The Development of “Civilization”—the term civilization has become a somewhat controversial term; but we will adopt Harman’s use of the word, meaning urban settlement.

1. Production of surpluses—people were able to live in cities because of Agri-Culture, the production of food beyond the immediate need for survival—surplus food—became the norm. This allowed people to regularly engage in other activities, rather than to work to assure their own survival


2. Control of the Surplus—living in urban areas meant living in groups larger than one’s extended kin network and meant that the values of cooperation and repricocity declined, and that the control of surplus food production was up for grabs


3. Armed force—professional soldiers developed along with urban living area, both to “protect” the urban population, and to help expropriate the surplus.



4. Accounting for the surplus—with the development of the surplus there also grew a need to account for it—to be able to tell where the surplus went, and to whom; and, eventually, at what cost. The need for this accounting system led not only to the profession of Certified Public Accountants, but contributed to the development of writing and counting—and to the development of a recognizable class system.


5. Kings and priests—with the turn to Agri-Culture, it became important to people to keep track of the season, and to be able to read and reckon when the best time to plant was. It also became increasingly important for someone to be able to foretell when misfortune would occur—or, even better, to stave off that misfortune. Among many peoples, the development of a priestly class reinforced the emergence of a ruling class, because of their claim of a special relationship with a particular deity.
