frequently inherited than acquired, power tends to be more or less cen-
tralized, and individuals have specialized occupations.
Today, thanks to settlement and urbanization, virtually everyone
lives in a complex society; yet this was not always so. It has been pointed
out that a typical person living about 8,000 years ago in a village in
Mesopotamia, the eastern arc of the Fertile Crescent, would have been a
member of a community of a few hundred people at most, nearly all of
them fairly close relatives. Almost all members of that community
would have lived similar lives that revolved around daily work in the
fields and would have possessed similar skills. Important life decisions
would have been made within each family group. But a mere three
millennia later, the record shows that life in the very same place was
extraordinarily different. By 5,000 years ago, there had been a total
change in the nature of Mesopotamian society—at that point, some of
its members were royalty, others were craftspeople, yet others slaves.
Basic life decisions affecting individuals were passed down the hierar-
chy, from on high, and an apparatus to enforce conformity with social
norms was in place. Economic roles had become specialized: each indi-
vidual plied a particular trade and was dependent on other members of
the society with different skills. The town itself might have swelled to a
population of thousands. For the individual in ancient Mesopotamia,
the change in lifestyle that came with rapid adoption of complex social
structures was enormous.
This was equally true of other parts of the world, as societies changed
and evolved along with their economic bases. Archaeologists have iden-
tified five regions in addition to Mesopotamia in which autonomous com-
plex societies spontaneously emerged in the eventful two millennia that
spanned about 6,000 to 4,000 years ago. Plausibly, every other complex
society today has ultimately inherited its structure from one or more of
these original six, through conquest or through contact of some other kind.
In the Near Eastern region, ancient Egyptian society acquired its complex
structure in the period after about 5,500 years ago. In India’s Indus Valley,
the Harappan culture evolved out of a tradition of village farming that
began to develop about 7,000 years ago and had begun the advance to a
full-blown civilization by a little under 5,000 years ago. In northern and
central China, early farming communities began to coalesce into complex
urban societies at about the same time. It was a little later, beginning at
about 3,500 years ago, that complex societies began to be seen in Central
America, with the emergence of the Olmec culture. And in South America
the origins of the great civilizations of the Andes can be detected earlier
than that, maybe as long ago as 5,000 years.
