Key Events
As you read, look for the key events in the
history of early humans and the beginnings
of civilization. 
• Paleolithic peoples learned how to adapt
to their nomadic lifestyle, improve on their
primitive tools, and use fire to their
advantage, thus enabling them to create
a more sophisticated human culture. 
• The agricultural revolution of the Neolithic
Age gave rise to more complex human
societies that became known as the first
civilizations.

listen to the audio again.
Early hominids called australopithecines
were primarily herbivores, but the
development of stone tools, which
allowed them to remove flesh from
animal carcasses, meant that later
hominids, such as Homo habilis, could
eat meat regularly.
Before History
• The period before history–prehistory–is
the period for which we have no written
records. 
• We know about prehistory from
archaeological and biological information. 
• Archaeologists and anthropologists create
theories based on this information. 
• Archaeology studies the structure of past
societies by analyzing the artifacts–tools,
household items, weapons, buildings,
artworks, religious figures, etc.–people left
behind.

Before History (cont.)
• Anthropology focuses more on culture by
studying artifacts and human remains–
human fossils. 
• For example, by studying tools and
weapons scientists create theories about
the economic and military structures of a
society. 
• Examining bones and hides tells us about
the diet of people.
(pages 19–21)
Click the mouse button or press the
Space Bar to display the information.
Before History (cont.)
• Archaeologists and anthropologists use
scientific methods to create their theories. 
• One of the most important scientific tasks
is dating prehistorical artifacts and fossils. 
• One valuable dating method is
radiocarbon dating. 
• This method dates accurately up to
50,000 years old. 
• Thermoluminescence measures
accurately up to 200,000 years old.
(pages 19–21)

Before History (cont.)
• Biological methods such as DNA and
blood molecule analyses also give us
information about the societies of
prehistory.
(pages 19–21)
Before History (cont.)
What artifacts from contemporary culture
would best show contemporary ways of
life, beliefs, and values to archaeologists
and anthropologists ten thousand years
from now? Explain what these artifacts
would teach future peoples about us.
(pages 19–21)
Early Stages of Development
• The earliest humanlike beings, called
australopithecines (“southern apes”) by
their discoverer, Donald Johanson, lived
in Africa three to four million years ago. 
• Australopithecines were the first
hominids (creatures that walk upright)
to make stone tools.
(pages 21–22)
Click the mouse button or press the
Space Bar to display the information.
Early Stages of Development (cont.)
• Homo erectus marks the next stage of
human development. 
• This species dates from about 1.5 million
years ago. 
• These hominids used larger and more
varied tools, and were the first to move
into parts of Europe and Asia. 
• They could migrate into colder areas
because they were the first beings to
make fires deliberately.
(pages 21–22)
Click the mouse button or press the
Space Bar to display the information.
Early Stages of Development (cont.)
• Homo sapiens (“wise human being”)
emerged about 250,000 years ago. 
• Two subgroups developed from Homo
sapiens: Neanderthals and Homo
sapiens sapiens. The Neanderthals died
out, possibly as a result of conflict
between the two groups. 
• Homo sapiens sapiens was the first
group that looked like us. 
• They appeared in Africa between 150,000
and 200,000 years ago. 
• All humans today belong to this subgroup
of Homo sapiens.

Early Stages of Development (cont.)
Why did it take Homo sapiens sapiens
tens of thousands of years to spread over
the world?
Groups of these people moved beyond
their old hunting grounds at a rate of
probably only two to three miles per
generation.

The Hunter-Gatherers of the
Old Stone Age
• A basic distinguishing feature of human
beings is making and using tools. 
• Early tools were made of stone. Therefore,
the term Paleolithic Age (“old stone”)
designates the earliest period of human
history. 
• The Paleolithic Age is from 2,500,000 to
10,000 B.C.
(pages 22–25)
Click the mouse button or press the
Space Bar to display the information.
The Hunter-Gatherers of the
Old Stone Age (cont.)
• Paleolithic people hunted game and
gathered nuts, berries, fruits, and wild
grains. 
• Over the centuries they developed better
hunting tools like spears, bows and
arrows, harpoons, and fishhooks. 
• They were nomads (people who move
from place to place) because they had to
follow the vegetation cycles and animal
migrations. 
• Scientists speculate these nomads lived
in bands of twenty to thirty people. (pages 22–25)
Click the mouse button or press the
Space Bar to display the information.
The Hunter-Gatherers of the
Old Stone Age (cont.)
• Most of Paleolithic life was organized
around and devoted to finding food. 
• Probably both men and women found
food, with men hunting and women
gathering. 
• Women probably stayed close to camp
because of bearing and raising children.
(pages 22–25)
Click the mouse button or press the
Space Bar to display the information.
The Hunter-Gatherers of the
Old Stone Age (cont.)
• Paleolithic men and women may have
been roughly equal because they shared
the vital responsibility of finding food. 
• Probably both made decisions that
affected the group. 
• The word technology refers to what we
make to sustain ourselves and control our
environment. 
• Stone tools were made by using a harder
stone like flint to create an edge on
another stone.
(pages 22–25)
Click the mouse button or press the
Space Bar to display the information.
The Hunter-Gatherers of the
Old Stone Age (cont.)
• The most common early stone tool was
the hand axe. 
• Later Paleolithic people added a handle
to the stone axe. 
• These tools were used to kill and butcher
animals, cut plants, dig up roots, and cut
branches to build shelter.
(pages 22–25)
Click the mouse button or press the
Space Bar to display the information.
The Hunter-Gatherers of the
Old Stone Age (cont.)
• Early shelter was in caves. 
• Later Paleolithic people fashioned houses
and huts, often using wood as a frame
that was then covered with hides.
Sometimes they used animal bones for
the frame.
(pages 22–25)
Click the mouse button or press the
Space Bar to display the information.
The Hunter-Gatherers of the
Old Stone Age (cont.)
• Paleolithic people used fire systematically
as long ago as five hundred thousand
years. 
• Fire gave warmth, it fostered a sense of
community, it scared away wild animals,
flushed out animals for hunting, and
cooked food. 
• Fire was especially important as a source
of warmth during the Ice Ages, the most
recent of which lasted from about
100,000 to 8000 B.C.

Click the mouse button or press the
Space Bar to display the information.
The Hunter-Gatherers of the
Old Stone Age (cont.)
• That even Paleolithic people created art
shows that art is important to human life. 
• One of the largest discoveries of
Paleolithic art, done between 25,000 and
12,000 B.C., is at Lascaux, France. 
• The paintings are in underground caves. 
• Most of the images are of animals. 
• Probably these paintings were used in
magical or religious rituals to bring about
a successful hunt.

The Hunter-Gatherers of the
Old Stone Age (cont.)
The Paleolithic cave paintings probably
were part of a magical or religious ritual
to ensure a successful hunt. Few people
in contemporary times believe art has
this kind of power, yet art continues to be
a vital human activity. What are other
functions of art?
Possible answers: We learn from art,
and we get pleasure from experiencing
the beautiful.

Early civilizations’ food surpluses were
made possible by a variety of agricultural
innovations. Among these was the
crossbreeding of crops. In the Indus
Valley, for example, crossing local
goatsface grass with Western Asiatic
enmer wheat produced bread-wheat.
The Neolithic Revolution
• Human survival depends on the
systematic growing and storing of food,
an accomplishment of the people of the
Neolithic Age. 
• After the end of the last Ice Age (8000
B.C.), the Neolithic Revolution began. 
• The word neolithic is Greek for “new
stone.” 
• The revolution was a change from hunting
and gathering to systematic agriculture.
(pages 27–30)
Click the mouse button or press the
Space Bar to display the information.
The Neolithic Revolution (cont.)
• Systematic agriculture means planting
crops and domesticating (taming)
animals for food, clothing, and work. 
• Some historians believe that this
agricultural revolution was the single most
important event in human history. 
• The ability to acquire food regularly gave
humans greater control over their
environment and made it possible to give
up nomadic ways of life for settling into
communities, a step vital for the
development of civilization.

Click the mouse button or press the
Space Bar to display the information.
The Neolithic Revolution (cont.)
• Systematic agriculture developed all over
the world between 8000 and 5000 B.C. 
• Mesoamericans (inhabitants of presentday Mexico and Central America), for
example, grew beans, squash, and maize
(corn). 
• Systematic agriculture gave rise to
permanent settlements, which historians
call Neolithic farming villages. 
• One was Jericho, in Palestine. 
• The largest was Çatal Hüyük, in presentday Turkey.

Click the mouse button or press the
Space Bar to display the information.
The Neolithic Revolution (cont.)
• Archaeologists found 12 products that
were grown in Çatal Hüyük and evidence
of widespread domestication of animals. 
• Because of increased food production
and storage, people had more food than
they needed. 
• These surpluses allowed some people to
do work other than farming. 
• Artisans made such things as jewelry
and weapons. These items fostered trade.
(pages 27–30)
Click the mouse button or press the
Space Bar to display the information.
The Neolithic Revolution (cont.)
• Çatal Hüyük also had shrines to and
statues of gods and goddesses. 
• These show that religion was gaining
importance during the Neolithic period. 
• The Neolithic period brought many
important changes: more complex
communities were developed, trade
caused people to specialize and a division
of labor developed, basic crops were first
cultivated, and cloth was first woven.

The Arts Paleolithic cave painters used a variety of
techniques. They daubed, dotted, ad sketched, using
charcoal or pigments from the earth. Painters of
different eras often worked on the same cave walls.
At Lascaux, France, 13 eras are evident.
Kamoya Kimeu One of the greatest fossil hunters
in the world is an African archaeological excavator
named Kamoya Kimeu. Working as an assistant to
Dr. Louis Leakey, Dr. Mary Leakey, and their son
Richard Leakey, he is responsible for finding some
of the most important hominid fossils in the later part
of the twentieth century. Kimeu jokes that the fossils
“speak” to him, accounting for his amazing ability for
unearthing the remains of human ancestors. Kamoya
Kimeu is currently curator of prehistoric sites for the
National Museums of Kenya.

Understanding Map
Projections
Why Learn This Skill?
On some maps, Greenland appears to be larger than
Australia. Australia, however, actually has a larger landmass
than Greenland. Have you ever wondered how this happens?
Why do flat maps distort the size of landmasses and bodies
of water? The answer lies in understanding the ways that flat
maps are constructed.
This feature can be found on page 26 of your textbook.
Understanding Map
Projections
Learning the Skill
To make flat maps, mapmakers project the curved surface
of Earth onto a piece of paper. This is called a map projection.
Unfortunately, the process is not exact. Different kinds of
projections can accurately show either area, shape, distance,
or direction. No one map, however, can show all four of these
qualities with equal accuracy at the same time.
This feature can be found on page 26 of your textbook.
Understanding Map
Projections
Learning the Skill
Mapmakers try to limit the amount of distortion by using
different kinds of map projections. A conformal map shows
land areas in their true shapes, but their actual size is
distorted. An equal-area map shows land areas in correct
proportion to one another but distorts the shapes of the
landmasses.
This feature can be found on page 26 of your textbook.
Understanding Map
Projections
Learning the Skill
The map below is a Cylindrical Projection (Mercator).
Imagine wrapping a paper cylinder around the globe. A light
from within the globe projects its surface onto the paper.
The resulting conformal projection
makes Alaska appear larger than
Mexico. Distortion is greatest near
the North and South Poles.
This feature can be found on page 26 of your textbook.
Understanding Map
Projections
Learning the Skill
A Conic Projection is formed by placing a cone of paper over
a lighted globe. This produces a cross between a conformal
and an equal-area map. This projection is best for showing
