This quotation is typically attributed to the German
philosopher Arthur Schopenhauer, but it does not appear in any of
Schopenhauer’s published works. What Schopenhauer actually wrote was:
“Der Wahrheit ist allezeit nur ein kurzes
Siegesfest beschieden, zwischen den beiden langen Zeiträumen, wo sie
als Paradox verdammt und als Trivial gering geschätzt
wird.” (“Truth is allowed only a brief celebration of
victory, between two long periods, during which it is condemned as
paradoxical and disparaged as trivial.”) From Die Welt als Wille und Vorstellung (The World as Will and Representation),
first published in Germany in 1818.

There is, of course, facial hair above and below the lips in
the form of mustaches and beards among the adult males in most human
populations. However, the presence or absence of this facial hair varies
greatly. In some human societies, such as the San Bushman of Africa’s
Kalahari Desert and the Yanomamö of South America’s Amazon Basin, adult
males typically have little or no facial hair. Some non-human primates also
have facial hair: the male orangutan often grows a beard, and both male and
female patas monkeys typically have well-developed mustaches and beards in
adulthood.

Some baboon species (e.g., the hamadryas baboon of Ethiopia) that inhabit
open, exposed environments have a flexible, multi-layered social
structure, in which several harems combine to form “clans” that forage
together during the day and then combine with other clans to share a
common sleeping area at night. This enables the baboons, while
maintaining their pattern of forming exclusive harems, to form very
large groups of up to 750 individuals that are effective defenses
against predators during the hours of darkness.

In the modern world, ethnic identities are not as uniformly
strong as they are in traditional societies. Some people tend to remain
faithful to their cultural origins, while others—especially the
young—prefer to embrace innovation and change. But the tremendous
increase in contact among the world’s cultures made possible by
industrial technologies of interaction and later by the invention of
digital technologies—combined with the hugely accelerated pace of
technological and cultural change—has in recent years caused many ethnic
traditions to lose their former power and importance, much to the
despair of the older generations.

As I have previously explained in greater detail in the
introduction, for many decades, the familiar term “hominids” was universally
used by anthropologists, paleontologists, and all other scientists to refer
to the various species of prehistoric and modern humans. But “hominids” fell
out of favor during the 1990s, when advances in DNA analysis showed that
gorillas and chimpanzees are genetically closer to humans than had been
previously assumed. As a result of these findings, all of the great apes
were reclassified and grouped together into the family Hominidae. In the years since this
reclassification took place, anthropologists have generally favored using
the term “hominins”—on the theory that it identifies humanity as belonging
not to the family Hominidae but rather to
the sub-family Homininae and/or the tribe
Hominini. However, since the
Hominini includes chimpanzees and the
Homininae includes both chimpanzees
and gorillas—both of which are quadrupedal apes that are not human and are
not part of the human family tree—I have decided, with apologies to my
fellow anthropologists, to use the more familiar term “hominid” in this
book, since it is addressed to the general reader as well as to the scholar
and scientist.

Even the kangaroo (which is not a placental mammal but
rather a marsupial), with its specialized ability to stand comfortably
on its hind legs and to run across the landscape with great speed by
jumping with its hind legs, must get down on all fours when it walks.
And the kangaroo is burdened by an immensely heavy tail, required to
counterbalance its forequarters. Even when the kangaroo is standing
erect, its spine is held not in a vertical position but rather at an
angle, halfway between vertical and horizontal.

Gen Suwa noted that the canine teeth of Ardipithecus had
become significantly reduced when compared with those of its likely
ancestors. “In the hominid precursors of Ar.
ramidus, the predominant and cardinal evolutionary
innovations of the dentition were reduction of male canine size and
minimization of its visual prominence … The fossils now available
suggest that male canine reduction was well underway by six million
years ago.” See Gen Suwa et al.,

Monogamy is common among birds, because once the female has
laid the eggs, either parent can perform all the remaining tasks
required to care for the offspring, from sitting on the eggs to keep
them warm to protecting and feeding the nesting chicks. Thus it stands
to reason that two birds would generally have a better chance of
successfully raising a nest of offspring than would a single bird. But
monogamy is rare among mammals, including primates, among which the care
and feeding of the young is primarily or exclusively the burden of the
female, the giver of milk (although among a few monogamous primate
species, the father tends to become the preferred beast of burden).
There are several monogamous primates, including gibbons, siamangs, titi
monkeys, and marmosets, but in every one of these species the primary
group consists of a single breeding pair. Humans are the only primates
that form monogamous families that remain integrated within larger
groups of cooperating adults.

In The Spark That Ignited Human
Evolution (Albuquerque: University of New Mexico Press,
2009), 173, Frances Burton, an anthropologist at the University of Toronto,
writes: “It is hard to identify why the Ancestor [the earliest hominid]
first approached fire. It surely must have occurred, however, somewhere
between 7 and 10 million years ago.” On the other hand, Steven R. James, an
anthropologist at the California State University at Fullerton, wrote in
1989 that “there are no actual hearths until the appearance of the
Neandertals … at the end of the Middle Pleistocene [approximately 130000
years ago]. Much of the evidence [for the human use of fire] prior to this
time is equivocal, and natural processes may explain it.” See Steven R.
James, “Hominid use of Fire in the Lower and Middle Pleistocene: A Review of
the Evidence,” Current Anthropology 30,

It is no accident that those species of non-human primates
who have adapted to a terrestrial existence—including baboons, vervets,
and patas monkeys—never venture far from the safety of the trees and
high cliffs that they use as sleeping places when darkness falls. Even
the chimpanzee, hardly a terrestrial species, always sleeps in the
trees, even though, due to its large size, it must construct a sleeping
platform out of tree branches that is strong enough to support its
weight. Only the massive gorilla, which lives in mountain habitats where
large predators are rare, and is strong enough to overpower most
predators, sleeps on the ground at night.

The various emerging humans that have been given their own
status as separate “species” to date include Homo habilis, Homo ergaster, Homo rudolfensis, Homo erectus, Homo
antecessor, Homo heidelbergensis, Homo rhodesiensis, and Homo
floresiensis. Some of them, such as H. habilis and H.
ergaster, are very ancient and have long been extinct,
while others, such as H.
floresiensis, may have survived until as recently as twelve
thousand years ago. Still others, especially Homo heidelbergensis, were so advanced that they may not
have been emerging humans at all but rather early forms of modern
humans. Precisely how all of the many fossil remains of the various
emerging humans should be classified continues to be the subject of
lively debate among prehistorians and will doubtless remain so for a
long time to come.

In captivity, however, the chimpanzee has demonstrated an
uncanny degree of casualness in handling and using fire—complete with
the ability to smoke cigarettes and cigars, a behavior that is described
in detail in A. S. Brink, “The Spontaneous Fire-Controlling Reactions of
Two Chimpanzee Smoking Addicts,” South African
Journal of Science 53 (1957), 241–247. One particularly
precocious chimpanzee was even capable of gathering dry twigs together,
lighting them with a cigarette lighter, adding more twigs to this little
fire, and toasting a marshmallow. See Frances D. Burton, Fire: The Spark That Ignited Human
Evolution (Albuquerque: University of New Mexico Press,

Several of the more primitive primate species, however, are
nocturnal in nature. Aside from a few species of “night monkeys”
(aotidae) that live in Central
and South America, most of these nocturnal primates belong to a more
ancient and more primitive suborder of primates called “prosimians”
(literally, “before monkeys”) that include dwarf lemurs, tarsiers, bush
babies, galagos, lorises, and pottos. As a rule, the nocturnal
prosimians tend to be rare, relatively small-brained, and solitary. Most
of them survive in small numbers in the more remote habitats of Africa
and Madagascar.

The release of melatonin is also governed by the normal

With apologies to the French anthropologist Claude
Lévi-Strauss, who published The Raw and the
Cooked: Mythologiques, volume 1 in 1964, a classic work
that explored the food mythologies of numerous societies. In it,
Lévi-Strauss concluded that all human cultures distinguish between food
in its natural state (“the raw”) and food that has been processed by
human activity (“the cooked”). He further theorized that the process of
cooking was viewed in all cultural mythologies as the crossing of the
boundary that exists in the human mind between nature and
culture.

It should be noted that Aiello and Wheeler argued that the
increase in brain size between the early hominids and the emerging
humans was most likely due to the addition of substantial amounts of
meat in the hominid diet, and they assumed that cooking was invented
much later, closer to 250000 years ago. But Wrangham makes a convincing
case that cooking was indeed responsible for the first and most dramatic
increase in brain size, and his argument has been strengthened by the
steady accumulation of evidence that hominids were already using fire on
a regular basis well before one million years ago. See Richard Wrangham,
Catching Fire: How Cooking Made Us
Human, 96–127.

Just as the human embryo has a tail and other archaic

have a considerable amount of fine hair all over its body before it is

weeks before birth.

In The Palaeolithic Settlement of
Asia (Cambridge: Cambridge University Press, 2009), Robin
Dennell explains in detail how changes in geology and climate resulted
in a huge expansion of grasslands in Asia and Africa and that by three
million years ago, the grasslands of the two continents had merged into
a vast belt of savannah habitats that stretched uninterrupted from West
Africa to Northern China. Dennell theorized that this unbroken belt of
grasslands provided a pathway for the migration of hominids north out of
Africa and eastward all the way to the Pacific shores of East
Asia.

The Schöningen javelins described in chapter 2 provide one
of the rare exceptions. These wooden spears, fortuitously preserved in
the highly acidic environment of German peat bogs for four hunderd
thousand years, showed that the manufacture of wooden artifacts by
emerging humans was already in an advanced state by the beginning of the
Middle Paleolithic approximately three hunderd thousand years ago. Yet
of all the billions of wooden artifacts that were doubtless created by
the hominids who roamed the earth for several million years, only these
four objects, some wooden artifacts from Bilzingsleben in Germany, and a
single spear point from Clacton, England, have been found that date from
before fifty thousand years ago.

While gold, silver, and copper were used extensively
throughout the Americas in pre-Columbian times, these metals were used
primarily for the manufacture of jewelry and other objects that
functioned as symbols of wealth and status. The techniques we usually
associate with metallurgy and that characterized the technologies of the
Bronze Age and Iron Age cultures in Europe and Asia—the smelting of
ores, casting of metal into shapes, mixing of molten metals to create
alloys, and the tempering of finished metal objects—were rudimentary in
pre-Columbian America and were not central to their technologies. In
fact, in some of the most advanced of these civilizations—such as the
Mayan civilization of Guatemala and the Yucatán Peninsula—metal
artifacts played only a marginal role and were not essential components
of their military, political, or economic
activities.

A few instances of nest-sharing between adults have been
observed between consort pairs of bonobos, which occasionally share

regularly construct their own nests and use them to sleep apart from
their mothers.

Remains from Paleolithic sites in eastern Europe indicate
that as long as twenty-seven thousand years ago, prehistoric people had
already developed sophisticated techniques of weaving and sewing. They
made cordage, knotted netting, wicker basketry, and woven and twilled
textiles sewn together with bone needles. In fact, the advanced state of
weaving and sewing that was already evident by twenty-seven thousand
years ago indicates that these technologies had actually originated much
farther back in time. Finally, many of the Venus figurines recovered
from these time periods are inscribed with patterns and designs
suggesting that the people of those ancient societies were customarily
wearing woven, tailored clothing.

Since women in preindustrial societies typically bore
several children during their lifetimes, it can be estimated that as
many as 10 percent of all human mothers died in childbirth throughout
all but the most recent decades of human history. This high rate of
mortality in human childbirth still exists throughout much of the
developing world, and it continues to be the norm in much of sub-Saharan
Africa.

The spear-thrower or atlatl is a short stick with a cupped
or hooked end that is held in the throwing hand, with the hooked end
fitted into the butt end of the spear, and used to increase the
effective length of the hunter’s throwing arm. The use of a
spear-thrower makes it possible for a spear to be hurled with
significantly greater force and speed than is possible when a spear is
thrown while held only in the hand. A light spear or javelin launched
with a spear-thrower can attain speeds of 150 miles per hour and has
enough force to pass entirely through the body of an antelope when
thrown from a distance of less than twenty-five feet. Spear-throwers
first appeared about thirty thousand years ago and were still in use
until modern times by hunter-gatherers all over the
world.

The term “petroglyph” was originally coined in the

man-made design on a rock or stone surface, whether carved or painted,
either out in the open or on the walls of caves.

Homo floresiensis stood
only three feet tall and had a brain no larger than the typical
chimpanzee brain. But the anatomy of its brain case indicates that its
prefrontal lobes—the area of the brain devoted to conscious thought—may
have been more highly developed than the corresponding regions of the
brains of early hominids. This suggests that Homo floresiensis may have been the offshoot of a
Homo erectus population that had
become isolated on Flores Island when the sea levels rose during
a warming period in the global climate. See P. T. Brown, et al., “A New

The Paleolithic or “old
stone age” technically refers to the entire span of time during which
the hominids evolved from the earliest bipedal forms such as Australopithecus to the first anatomically
modern humans, because the remains of stone tools were by far the most
common artifacts found in prehistoric habitation sites throughout this
long period.
The Paleolithic is usually subdivided into three eras based on tool types: (1) the Lower Paleolithic, which begins roughly three million years ago with the manufacture of the first crude Oldowan pebble tools by the early hominids and continues throughout the 1.5-million-year period during which the emerging humans such as Homo erectus made their more finely worked Acheulean hand axes; (2) the Middle Paleolithic, which begins approximately 250000 years ago and is generally associated with the Neandertals and their Mousterian flake tools; and (3) the Upper Paleolithic, which begins roughly fifty thousand years ago and corresponds to the time of the anatomically modern humans such as the Cro-Magnons, who made the finest and most varied stone tools from long, thin blades of fine-grained stone such as flint and obsidian.
The term “Paleolithic” is useful here because it distinguishes the societies of the nomadic hunters and gatherers from those of the Neolithic or “new stone age,” which begins shortly before the development of agriculture. During the Neolithic, the larger stone tools are increasingly made by grinding and polishing rather than by flaking, while the smaller stone tools made by flaking—generally called microliths— became very small and specialized. In the later years of the Neolithic, the use of pottery became widespread, and the remains of broken pottery eventually became the most common type of artifact in prehistoric habitation sites. In between these clearly-defined periods, there is a somewhat vague middle ground called the Mesolithic or “middle stone age.” This is sometimes used as a catch-all term for prehistoric cultures that do not fit neatly into the categories of either Paleolithic or Neolithic.
I have used the term “Upper Paleolithic” extensively in this chapter to refer to the period when anatomically modern humans appeared in Europe roughly fify thousand years ago—and who lived by nomadic hunting and gathering—in order to distinguish them from the food-producing societies of the Neolithic that first began to appear fifteen thousand years ago and that will be described in detail in chapter 6.
(7)
The anatomically modern humans of the Upper Paleolithic
were the first hominids to show clear evidence of distinct cultural
traditions. Although many different Upper Paleolithic cultures have been
identified in different areas of the world, those of Europe are the best
known and have been the most carefully studied. While most of these
cultures overlap in time with each other, they are usually organized in
a rough chronological order. The oldest of these cultures was that of
the Châtelperronians, who lived roughly thirty-thirty thousand years
ago. They were followed by the Aurignacians, Gravettians, and
Solutreans. The most recent culture was that of the Magdalenians, who
survived in Europe until approximately eleven thousand years
ago.

Homo heidelbergensis was
a large-brained emerging human so similar to the more advanced forms of
Homo erectus that many scientists
consider them to be essentially the same species. It was originally
identified from a fossil jaw found near Heidelberg, Germany in 1907, and
other remains of this hominid have since been found in Africa and
western Asia. Homo heidelbergensis is
the evolutionary branch of Homo
erectus that is most likely to have been ancestral to the
Neandertals as well as to anatomically modern
humans.

The plump yellow grain that grows in large cobs on tall
fleshy plants is known throughout most of the world as “maize” or
“mealie” but is called “corn” in the United States, Canada, Australia,

The horse was domesticated about five thousand years ago in
the steppes, or grasslands, of present-day Kazakhstan, nearly a thousand
miles north and east of the Fertile Crescent, where it first became
important as a means of transportation. The important story of the
domesticated horse will be discussed at length in the next chapter,
where we will see how, as one of the key elements in the technologies of
interaction, the horse contributed significantly to the emergence of
cities and the emergence of urban civilization.

In deference to the sensitivities of atheists, agnostics,
and non-Christians, scientists and scholars have recently begun using
the term “BCE,” meaning “Before the Common (or Current) Era,” in
preference to the traditional “BC” or “Before Christ.” For the same
reason, they have also begun using the corresponding term “CE,” meaning
“Common (or Current) Era,” instead of the more traditional “AD” or
“Anno Domini” (“the year of our
Lord”). While not meaning to take issue with the logic of this
change—but for the convenience of readers who are not be familiar with
these terms—I have continued using the more traditional “BC” and “AD” in
this book for dates before and after the birth of
Christ.

Perhaps this is why many behavioral scientists in the
twentieth century embraced the preposterous idea that humans are the
only animals capable of reason and emotion—as if such mental activities
had emerged full-blown for the first time in the history of life on
Earth with the appearance of Homo
sapiens. Such views—which were never supported by
credible scientific evidence—could only have been taken seriously by
someone who had never lived with an intelligent animal such as a dog,
cat, horse, pig, monkey, or parrot. People who have lived intimately
with such animals are well aware that they are capable of both reason
and a wide range of emotions.

Moore’s exact words in 1965 were as follows: “The
complexity for minimum component costs has increased at a rate of
roughly a factor of two per year (see graph). Certainly over the short
term this rate can be expected to continue, if not to increase. Over the
longer term, the rate of increase is a bit more uncertain, although
there is no reason to believe it will not remain nearly constant for at
least ten years. That means by 1975, the number of components per
integrated circuit for minimum cost will be 65000.” Gordon E. Moore,

ENIAC contained 17468 vacuum tubes, each of which was
equivalent to a modern transistor. Since the 15-Core Xeon E7 V2
microprocessor contains 4.31 billion transistors, it would require the
equivalent of 4310000000 divided by 17468 or 246737 ENIACs to equal the
processing power of one 15-Core Xeon E7 V2 microprocessor. Each ENIAC
was 100 feet long, thus 246737 ENIACs laid end to end would measure
24673700 feet or 4673 miles in length. The weight of each ENIAC was
thirty tons or 60000 pounds. Thus, 246737 ENIACs would weigh 7402110
tons—equal to the weight of sixty-six Nimitz-class supercarriers
weighing 112000 tons each. The ENIAC cost $500000 to construct,
which in 2014 dollars amounts to approximately $6 million. Thus,
246737 ENIACs would have cost $1480422000000 to build in
2014.

Since the best vacuum tube computers of the 1950s averaged
a maximum consecutive running time of ten hours (or thirty-six thousand
seconds) before experiencing a vacuum tube failure, a computer as large
as 246737 ENIACs would probably run for only thirty-six thousand seconds
divided by 246737, or one-seventh of a second, before one of its
4310000000 vacuum tubes would fail.

Due to their small size and immense distance from Earth, no
planet outside of our own solar system has ever been observed directly.

Light travels at the speed of 670616629 miles per hour.

The term “biosphere” was coined by the Austrian geologist
and paleontologist Eduard Suess in 1875 to describe the total mass of
living things that inhabit the surface of the earth. Since the
environments that support life are all found only on the earth’s
surface, the physical mass of living organisms on our planet takes the
shape of a sphere—hence the term “biosphere.” The same logic was used in
the 1600s, when the Greek word atmos,
meaning “vapor,” was combined with the earth’s spherical shape to create
the word “atmosphere.”

Although Israel has never publicly acknowledged the
existence of its nuclear weapons program, it has never denied its
existence either. In 2002, Robert S. Norris and his colleagues described
the Israeli nuclear program as follows:
After Egyptian President Gamal Abdel Nasser closed the
Straits of Tiran in 1953, Israeli Prime Minister David Ben Gurion
began development of nuclear weapons and other unconventional
munitions. His protégé, Shimon Peres, played a central role in
securing an agreement with France in 1956 for a nuclear research
reactor. Physicist Ernst David Bergmann, director of the Israeli
Atomic Energy Commission, provided early scientific direction … With
French assistance, Israel built a nuclear weapons facility at Dimona
in the Negev desert. The Dimona site has a plutonium/tritium
production reactor, an underground chemical separation plant, and
nuclear component fabrication facilities.

Marine isotope stages (MIS), also known as “oxygen isotope
stages (OIS),” refer to periods in the earth’s geological history when
global temperatures became either warmer or cooler than they had been
during the preceding time period. These stages are determined by
measuring the ratio of two isotopes of oxygen—oxygen-16 and oxygen-18—in
the shells of marine organisms that were buried at different geologic
times in the sea floor. As the oceans become warmer, the proportion of
oxygen-18 in the shells decreases; as the oceans become cooler, the
proportion of oxygen-18 increases. There have been twenty-two of these
stages during the past million years, reflecting the alternating states
of global warming and global cooling as the ice ages have advanced and
retreated. Odd numbered stages, including MIS 1 (the past eleven
thousand years) and MIS 11 represent the warm periods, while even
numbered stages represent cold periods, including all of the major ice
ages that have occurred over the past million
years.

The exact number of nation-states is not only frequently
changing but is also subject to interpretation. For example, thirty new
nations came into being in the seven years between 1956 and 1963, when
the colonies of Africa achieved independence from Europe and became
independent nations. And the total number of nation-states increased
again by five during the 1990s, when a single nation-state, the former
Republic of Yugoslavia, fissioned into six independent nations: Serbia,
Croatia, Slovenia, Macedonia, Montenegro, and Bosnia-Herzegovina.
Moreover, it can sometimes be difficult to determine whether a given
political and geographical entity is in fact a nation-state in its own
right. For example, is Palestine a nation—as the Palestinians themselves
asserted in their Declaration of Independence in 1988—or is it a United
Nations mandate without any status as an independent nation, as the
Israeli government currently maintains? There is no consensus on this
point.
(24)
Between 1901 and 2000, no less than 177 new nation states
were created. See Philip G. Roeder, Where
Nation-States Come From: Institutional Change in the Age of
Nationalism (Princeton: Princeton University Press,
