Look in a mirror. What do you see? A human? Self-confident, we tell ourselves that we are a gifted species that can see further than any other. And, because of big brains, we are probably right. But smart as we are, we have a lot to learn. John

Many behavioral differences exist between chimps and humans, just as between chimps and gorillas or between gibbons and orangutans. But we are struck by how much the core of chimpanzee social life in the wild resembles some forms of human social organization, especially under great stress—in prisons, say, or urban and motorcycle gangs. or crime syndicates, or tyrannies and absolute monarchies. Niccolò Machiavelli, chronicling the maneuvering necessary to get ahead in the seamy politics of Renaissance Italy—and shocking his contemporaries, especially when he was honest—might have felt more or less at home in chimpanzee society. So might many dictators, whether they style themselves of the right or left persuasion. So might many followers. Beneath a thin varnish of civilization, it sometimes seems, there's a chimp struggling to bust out—to take off the absurd clothes and restraining social conventions and let loose. But this is not the whole story. Carl

The widely
renown Renaissance thinker, Niccolò Machiavelli,
was a Florentine statesman, writer, and political theorist.
Following his retirement from public service, Machiavelli
wrote at
length on the skill required for successfully running the state.
He is best known for his political treatise The
Prince, a short instruction book for
rulers that
attempts to lay out methods to secure and maintain political power.
Offering somewhat cynical recommendations, Machiavelli was
prescient in his realization that an individual's success is often most
effectively promoted by seemingly altruistic, honest, and prosocial
behavior. Although Machiavelli was one of the most brilliant and
original thinkers of the Renaissance, his name became synonymous with
deviousness, cruelty, and willfully destructive rationality. The
adjective "Machiavellian" emerged as a pejorative designation used to
describe those who manipulate others in an opportunistic and deceptive
way.
But Machiavelli was not alone in history. The Arthashastra , a treatise written in Sanskrit which means "the Science of Material Gain" or "Science of Polity," discusses theories and principles of governing a state. The Arthashastra is distinguished by its unabashed advocacy of "realpolitik." The original author, Chanakya, who was a Brahmin minister under Chandragupta Maurya, advocated that the ruler should use any means to attain his goal and his actions required no moral sanction. He has often been likened to Machiavelli by political theorists, and the name of Chanakya is reminiscent of a vastly scheming and clever political adviser. Prior
to the surge of
field studies of primate behavior in the 1950s and 1960s, the
foundation of human intelligence was thought to lie in the challenge of
tool making. But observational studies in the wild and in naturalistic
zoological colonies induced a growing realization of the sophistication
of social intelligence in primates. An interesting pair of
books
bearing the title Machiavellian
Intelligence present striking evidence of primate social
complexity. The books' titles were inspired by Franz de Waal's work, in
which he explicitly compared chimpanzee social strategies with the
advice offered four centuries earlier by
Machiavelli. An
intriguing account of a tangled social web in which
chimpanzees
live is incorporated in Franz de Waal's book Chimpanzee
Politics, which recounts de Waal's astute
observations
of the chimpanzee colony at the Burgers' zoo in Arnhem; de
Waal
describes episodes of ambition, social manipulation, sexual privileges
and power takeovers that could be attributed to human personalities,
but were preformed by (Machiavellian-minded) chimpanzees.
The contemporary understanding exemplified
in these
recent titles suggest that the keen observations of human
political interaction portrayed in the work
of Chanakya
and Machiavelli have a foundation in the recognizable social
complexity of humanity's closest primate relatives.
The
correlation between
social skill, group complexity, and brain size gives strong support
But the
human species, which
has inherited its Machiavellian intelligence from ancestral
great apes,
has
been further transformed by evolutionary pressures over several million
years. A 3½ million year old footprint in East
Africa
indicates that bipedal human ancestors had clearly diverged from the
great apes. By 2 million years ago, our
ancestors had larger heads and were somewhat
precocious; taller
and larger brained ancestors in the human lineage used symmetrical
pear-shaped tools (hand axes) 1.8 million years ago.
Over
this evolutionary period, the the human lineage developed a
capacity exhibited in nascent form by
chimpanzees - tool
making.
Beginning about 200,000 years ago, a new technique called Levallois, which produced carefully shaped flakes and points of stone, was practiced. Approximately 100,000 years ago anatomically modern humans carried tool-making kits that enabled the manufacture of specialist tools. Around 60,000 years ago, Homo sapiens sapiens had appeared, producing yet more sophisticated artifacts—blade tools, clothing, body ornaments, etc. The process of becoming human has been effectively depicted in the following video: During the course of this evolutionary process—the Paleolithic Revolution - our species was transformed from polygynous vegetarian quadrupeds into bipedal, monogamous, linguistic, tool-using hunter-gatherers. The transition from great apes to humans can be epitomized graphically as follows:
Amid this transition, Machiavellian intelligence was augmented and complemented by the development of technical (tool-making) intelligence and language. |

As a consequence
of their evolutionary advent, human hunter-gatherers, as
foragers, became top
predators
who lived off the yield of their surrounding habitat. With their
tool-making skills and ability to communicate and organize themselves
into groups, early hunter-gatherers were able to explore and settle new
environments. Until about 30,000 years ago, early
humans
dealt with immediate problems: deciding which food to eat, how to
survive the winter, how to avoid dangerous animals, where to find
shelter. They committed
themselves emotionally to a small piece of geography, a limited band of
kinsmen, and two or three generations into the future. Their mental
predispositions, like those of other animal species, were circumscribed
by the immediate horizon and by short-term problems. There
would
have been little point in worrying about the long term if immediate
threats such as predators and winter were not dealt with.
By 30,000
years ago, our
ancestors had colonized much of the planet. At the
peak of
the last ice age 20,000 years ago, they fabricated clothing and shelter
to survive the harsh conditions.
At the end of
the last ice age, when temperatures rose and the ice sheets receded,
plants and animals grew more abundant, and new areas were settled.
Foraging
humans had an impact
on their surroundings. By 11,000 years ago, intense hunting
and
expanding human populations contributed to the widespread destruction
of large quadruped mammals, such as the giant sloth, mastodon, mammoth,
and great elk. Hunting populations gradually intensified
their
subsistence by pursuing smaller animals; by fishing, collecting
shellfish, and exploiting other forms of aquatic life; and by making
plants of varied types and increasing part of their diet. By
10,000 years ago, groups of hunter-gatherers in the southwest Asia were
living in permanent settlements, harvesting wild cereals and
domesticating local animals, commencing the transition to human
agriculture (the Agricultural
Revolution ). Over the next 5,000 years
agriculture became
established independently in China,
southeast Asia, Europe, Africa, Mesoamerica, South America, and North
America.
The earliest agriculture was horticulture—the cultivation of small garden plots with hand tools such as digging sticks or hoes. Early agriculturists identified collections of plants and animals that could live with them in mutual advantage, forming human-centered biological communities that displaced species not immediately useful to humans. As agricultural populations grew, intensive cultivation of large fields emerged—eventually employing plows and draft animals. Since agriculture could support significantly
larger
populations,
settlement sizes increased proportionately. Large groups
lived in
permanent villages, surrounded by material structures and goods
compatible with sedentary living. Specialized
craftsmen
emerged, supported by the community as a whole, to
meet the
community's new requirements—the beginning of social
differentiation. During the
past
5,000 years until recent centuries, the predominant
form
of social organization was the agrarian state, exemplifyed
by the
following attributes:
