World History Unit 1The Rise of Civilizations Chapter 1, Section 1 Discovery of Early Humans in Africa
Objective of Lesson 1-1 • Understand how recent archaeological finds have contributed to our understanding of human origins. • Understand that the migrations of prehistoric peoples resulted in their spread throughout the world
Key Vocabulary • Hominids: the humans and human-like creatures that preceded them. • Anthropologists: the scientific study of hominids using bones and other remains. • Paleontologists: the study of fossil remains to determine the characteristics of prehistoric periods • Archaeologists: investigate prehistoric life by unearthing and interpreting the objects left behind by prehistoric people. • Artifacts: objects that were shaped by human hands and other remains of human life such as charcoal. • Radiocarbon dating: the process of measuring the rate of decay of radioactive carbon in organic remains.
People to Meet • Gen Suwa • Tim D. White • Donald C. Johnson • Louis Leakey • Mary Leakey
Places to Locate • Aramis • Hadar • Olduvai Gorge
Discovery of Early Humans in Africa--Overview • Prehistoric Finds in Africa • Human Origins • The Ice Ages • Human Culture • Dating Early Artifacts • Paleolithic Hunter-Gatherers
Dating Early Artifacts • Archaeologists and physical anthropologists face the problem of assigning a definite age to remains. • Among the techniques for determining the age of remains are radiocarbon dating and DNA analysis.
Dating Early Artifacts • Radiocarbon dating • Organic matter includes once living things • Small amounts of carbons absorbed by living things is radioactive • Radioactive carbon decays at a certain rate, thus indicating when plant or animal dies • Good only for matter less than 50,000 years old
Prehistoric Finds in Africa • In 1992, paleontologist Gen Suwa, in Ethiopia, discovered 4.4 million-year-old fossils belonging to the oldest direct human ancestor known. • In 1974, again in Ethiopia, two scientists uncovered a nearly complete skeleton of a 3.2 million-year-old hominid nicknamed “Lucy”. • In 1994 a reasonably complete skull of a Lucy-like hominid provided evidence that Lucy-like humanoids could walk upright.
Prehistoric Finds in Africa • Discovery of Lucy • Discovered by Donald C. Johnson and Tom Gray • Discovered at Hadar • Named after popular Beatles song • Most nearly complete skeleton of upright walking prehuman found to that time • A chin bone discovered in Kenya indicated upright walking at 4 million years ago
The First Hominids • Australopithecus, the first prehuman hominid, lived in eastern and southern Africa about 4.4 million years ago. • Scientists divide Homo—the genus of humans—into three species: Homo habilis, Homo erectus, and Homo sapiens.
The First Hominids • Australopithecus lived in humid forests of eastern and southern Africa • Ate fruit, leaves, and fish • Nomadic—constant search for food • No evidence for use of tools
Hominid Groups • Scientists used the Latin word Homo—or human—to name hominids and later humans • Scientists still not sure when humans became human • Genre of humans divided into three groups • Somewhat different body structures • Arrived at different times
Hominid Groups • Homo habilis: “person with ability,” first of the group of hominids that lived about 3-4 million years ago. • Homo erectus: “person who walks upright.” Lived about 1.5 million years ago. • Homo sapien: “person who thinks.” Lived about 200,000 years ago. All people today.
The Ice Ages • Between 2 million and 10,000 years ago, earth experienced four periods called the Ice Ages, during which only the middle latitudes were warm enough to support human and animal life. • Early human beings adapted to the Ice Ages by migrating to warmer places or developing strategies for keeping warm.
The Ice Ages • Many parts of the world fell to below freezing • Glaciers spread over several areas • Only middle latitudes remained warm enough for animal life • Between glacial periods, the earth warmed
The Ice Ages • As glaciers grew and oceans lowered by 300 feet, land bridges formed • Japan and Korea • Great Britain and Ireland • Malay Peninsula and Indonesia Islands • Asia and North America
Migrations • Homo erectus migrates to Europe and Asia • Reached Indonesian Islands 1.6 million years ago.
Human Culture • Culture includes the knowledge a people have, the language they speak, the ways in which they eat and dress, their religious beliefs, and their achievements in art and music. • One of the earliest cultural developments was the use of stone tools, which has led historians to apply the name “Stone Age” to the period before writing was widely established.
The Stone Age • Three periods based on tool making techniques • Paleolithic: Old Stone Age (2 million years ago to 12,000 B.C.) • Mesolithic: Middle Stone Age (12,000 to 8,000 B.C.) • Neolithic: New Stone Age (8,000 to 5,000 B.C.)
Paleolithic Hunter-Gatherers • Home habilis, who lived during the Paleolithic, are the oldest hominids known to have manufactured tools. • Home erectus, who began as food gatherers but became hunters by developing weapons, used fire and made clothing from animal skins. • Scientists disagree on when prehistoric peoples migrated out of Africa, but there is general agreement that Homo erectus was established in China and Europe by about 400,000 years ago. • By 50,000 B.C. prehistoric peoples had developed language, which allowed them to exchange ideas and pass their knowledge on to the next generation.
Homo Habilis • Lived in Africa 2.5 million to 1.5 million years ago • Research credited to Louis and Mary Leakey and later their son, Olduvai Leakey
Homo Erectus • From 1.5 million to 250,000 years ago • From Africa to Europe to Asia • Women gathered fruits; men scavenged for “killed” meat • Men later became hunters using spears and clubs—about 500,000 years ago
Homo Erectus • Learned to make fire • Protection from animals • Could live in caves—drove other animals out with fire • Cook food • Keep warm • Made clothing from animal skins
Migrations • Scientists disagree whether Homo Habilis or Homo Erectus migrated to Europe first • Homo Erectus reached Asia and Europe • Bones show Homo Erectus reached Java about 1.6 to 1.8 million years ago • Skeletal remains show Homo erectus clearly established in China 460,000 years ago
Language • Homo Erectus may have been talking to each other about 500,000 years ago • Language—one of humanities greatest achievements • Exchanging information on how to survive and pass along cultural • Continuance of culture
Section 2: The Appearance of Homo Sapiens—Overview The Neanderthals Homo Sapiens Sapiens The Neolithic Revolution
Overview of Section 2 • Homo erectus improved many aspects of life • Homo sapiens, the first modern human species, moved the human condition forward at a faster pace • Discovery in Zaire, Africa, shows humans used tools much earlier than thought—80,000 years ago
Objective of Lesson Section 2 • Know some of the achievements of the earliest humans. • Early humans produced tools and domesticate animals and crops.
Key Vocabulary • Domesticate: Taming an animal for human purposes. • Deity: Neolithic peoples believed in many gods or goddesses
People to Meet • Neanderthals • Cro-magnons
Places to Locate • Neander Valley • Lascaux • Vallon-Pont-d’Arc • Jericho • Catal Huyuk
The Neanderthals • Stood about 5.5 feet tall • Brains larger than modern humans • Stocky build—muscular • Able to adapt to colder climates • Nomadic hunters and gatherers • More sophisticated tools
The Neanderthals • Neanderthals, probably the first Homo sapiens, began spreading into Europe and Asia about 100,000 years ago from Africa • Their tool making ability was more sophisticated that Homo erectus. • Most lived in groups of 35-50 people, either in open-air camps or in non-permanent dwellings such as caves. • They were culturally advanced in their care for the sick and aged and their treatment of the dead.
Homo Sapiens Sapiens • Homo sapiens sapiens moved from Africa and into Europe and Asia • Intermarried Neanderthals • Gradually absorbed them • Neanderthal became extinct, leaving Homo sapiens sapiens the only hominids left on earth
Homo Sapiens Sapiens • Most scientists believe that modern humans, or Homo sapiens sapiens in Europe, originated in Africa about 50,000 years ago and soon came to dominate almost every continent. • The Cro-Magnons, the earliest Homo sapiens sapiens, brought with them improved technology and a more sophisticated culture. • The advances the Cro-Magnons made in tool making transformed human life by making long-distance travel possible and increasing the supply of food.
Homo Sapiens Sapiens • Cro-Magnons were taller, but not as robust • Better hunting and gathering techniques—more group oriented • Better hunting and then fishing instruments • Better stone axes allowed them to make canoes and travel in them long distances • Invented long distance weapons—bow and arrow, etc
Homo Sapiens Sapiens • The Cro-Magnons’ increased food supply had political and social consequences, including the cooperation of unrelated bands of Cro-Magnons and the evolution of rule-making and leadership. • Cro-Magnons at first lived in temporary structures, but as their hunting methods advanced, they built permanent communities • The Cro-Magnons were accomplished cave painters and sculptors. • More sophisticated burials
Homo Sapiens Sapiens • Cave paintings included accomplished artistry found in caves in Lascaux and Vallon-Pont-d’Arc, France • Historians disagree on painting rationale • To educate youngsters on the finer hunting points • Reaching out to the spiritual for help in their hunting activities
Homo Sapiens Sapiens • Better food supply brought higher population • By 15,000 B.C., there were two million people on the earth
The Neolithic Revolution • The end of the last Ice Age brings green—forrests and grasses • During the Neolithic period—named for its tremendous changes-- and immediately after, people gradually shifted from gathering and hunting food to producing food. • The Mesolithic period, during which people of domesticated animals and developed farming tools, was a forerunner of the Neolithic Revolution.
The Neolithic Revolution • In different parts of the world, the Neolithic Revolution took place at different times and involved different crops and animals. • Farming assured a steady food supply and enabled people to stay longer in one place, but it also required harder and longer work. • With the development of agriculture, people began to settle in agricultural villages instead of wandering as nomads.
The Neolithic Revolution: The Dawn of Agriculture • Neolithic farmers made agricultural work easier and more productive by inventing the plow and fertilizing their fields. • The relatively steady food supply quickened the pace of technological advance and led to the development of calendars, land ownership, and warfare. • Neolithic people believed in deities with the power to hurt or help people.
The Neolithic Revolution: The Dawn of Agriculture • Neolithic Revolution built slowly • Began at different times in different parts of the world • Middle East (8000 years ago) • China (5000 years ago)
The Neolithic Revolution: The First Villages • Food production increases population • By 4000 B.C., world population is estimated at 90,000,000 • People could settle in communities • Where soil was fertile and water abundant • Jericho: one of earliest villages; Israel occupied West Bank; 8000 B.C. • Catal Huyuk: early village; Turkey; 6300-7000 B.C.; largest village discovered so far
The Neolithic Revolution: Technological Advances • Invented the plow and trained animals to pull • Invented the loom and the wheel • Baked clay to construct buildings • Hammered metals for jewelry and weapons • The Iceman • Calendars created to track agriculature
The Neolithic Revolution: Technological Advances • Boundaries became important and warfare over boundaries was probable • Believed in deities, gods and goddesses
River Valley Civilizations The Economy of a Civilization The Rise of Cities Systems of Values Section 3, Emergence of Civilization
Lesson 1-3 Objectives • Understand that the earliest civilizations begin with the evolution of farming settlements into the first cities. • Know the kinds of economic, political, and social changes that resulted from the rise of cities.
Key Vocabulary • Civilization: The term comes from the Latin term “civitas” meaning “city.” A civilization is a highly organized society with an advanced knowledge of farming, trade, government, art and science. • Economy: The ways in which people use their environment to meet their material needs. • Artisan: Workers skilled in a craft. Artisans usually work with their hands.
