World History Unit 1 The Rise of Civilizations Chapter 1, Section 1 Discovery of Early Humans in Africa 3/17/2016 1 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 3/17/2016 2 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. 3/17/2016 3 People to Meet • • • • • Gen Suwa Tim D. White Donald C. Johnson Louis Leakey Mary Leakey 3/17/2016 4 Places to Locate • Aramis • Hadar • Olduvai Gorge 3/17/2016 5 Discovery of Early Humans in Africa--Overview • Prehistoric Finds in Africa • Human Origins • The Ice Ages • Human Culture • Dating Early Artifacts • Paleolithic HunterGatherers 3/17/2016 6 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. 3/17/2016 7 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 3/17/2016 8 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 millionyear-old hominid nicknamed “Lucy”. • In 1994 a reasonably complete skull of a Lucy-like hominid provided evidence that Lucy-like humanoids could walk upright. 3/17/2016 9 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 3/17/2016 10 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. 3/17/2016 11 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 3/17/2016 12 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 3/17/2016 13 Hominid Groups 3/17/2016 • Homo habilis: “person with ability,” first of the group of hominids that lived about 34 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. 14 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. 3/17/2016 15 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 3/17/2016 16 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 3/17/2016 17 Migrations • Homo erectus migrates to Europe and Asia • Reached Indonesian Islands 1.6 million years ago. 3/17/2016 18 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. 3/17/2016 19 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.) 3/17/2016 20 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. 3/17/2016 21 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 3/17/2016 22 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 3/17/2016 23 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 3/17/2016 24 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 3/17/2016 25 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 3/17/2016 26 The Neanderthals Homo Sapiens Sapiens The Neolithic Revolution Section 2: The Appearance of Homo Sapiens—Overview 3/17/2016 27 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 3/17/2016 28 Objective of Lesson Section 2 • Know some of the achievements of the earliest humans. • Early humans produced tools and domesticate animals and crops. 3/17/2016 29 Key Vocabulary • Domesticate: Taming an animal for human purposes. • Deity: Neolithic peoples believed in many gods or goddesses 3/17/2016 30 People to Meet • Neanderthals • Cro-magnons 3/17/2016 31 Places to Locate • • • • • Neander Valley Lascaux Vallon-Pont-d’Arc Jericho Catal Huyuk 3/17/2016 32 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 3/17/2016 33 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. 3/17/2016 34 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 3/17/2016 35 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 longdistance travel possible and increasing the supply of food. 3/17/2016 36 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 3/17/2016 37 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 3/17/2016 38 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 3/17/2016 39 Homo Sapiens Sapiens • Better food supply brought higher population • By 15,000 B.C., there were two million people on the earth 3/17/2016 40 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. 3/17/2016 41 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. 3/17/2016 42 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. 3/17/2016 43 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) 3/17/2016 44 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 3/17/2016 45 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 3/17/2016 46 The Neolithic Revolution: Technological Advances • Boundaries became important and warfare over boundaries was probable • Believed in deities, gods and goddesses 3/17/2016 47 River Valley Civilizations The Economy of a Civilization The Rise of Cities Systems of Values SECTION 3, EMERGENCE OF CIVILIZATION 3/17/2016 48 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. 3/17/2016 49 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. 3/17/2016 50 Key Vocabulary • Cultural diffusion: The exchange of goods and ideas when cultures come in contact with one another. • Myth: Traditional stories about how the earth was formed, how people came into being, and what they owed their creator 3/17/2016 51 River Valley Civilizations • Many early civilizations arose from farming settlements in river valleys. • Early river valley civilizations depended on the specialization of labor, advanced technology, a government to coordinated large-scale cooperative efforts, and a shared system of values and beliefs. • Some societies remained as small agricultural villages or hunter-and-gatherer bands. 3/17/2016 52 River Valley Civilizations • Four river valley civilizations – The Nile River: northeast Africa, present day Egypt – The Tigris and Euphrates Rivers: present day Iraq – Indus River: South Asia, present day India – Huang He: East Asia, present day China • What gave river valleys the upper hand in developing into civilizations? 3/17/2016 53 The Economy of a Civilization • An economy is the way people use their environment to meet their material needs • Economy depends on farmers growing surplus food 3/17/2016 54 The Economy of a Civilization: First Irrigation Systems • Farmers could develop a surplus of crops because early civilizations built massive irrigation systems and dikes and dams to prevent flooding. 3/17/2016 55 The Economy of a Civilization: Specialized labor • Workers skilled in a craft, called artisans, became increasingly productive and creative. • The period that follows the Stone Age is known as the Bronze age because bronze replaced stone as the chief material for weapons and tools. • Expensive, bronze was used by kings, priests, and soldiers. 3/17/2016 56 The Economy of a Civilization: Specialization of Labor • Jewelry, eating utensils, weapons and other goods were hammered out of copper, lead, and gold • Alloys were made from various metal mixtures—bronze was the most important—made from copper and tin – Weapons – Tools 3/17/2016 57 The Economy of a Civilization: Long-Distance Trade • At first trading with own communities • Land routes emerged • Long-distance trade accompanied the rise of early civilizations. • People became adept at handling wind power and navigating rivers • Goods and ideas were shared across cultures world wide: cultural diffusion •3/17/2016 58 Living Together in Cities: Planning and Leadership • As civilizations grew more prosperous and complex, cities faced the need to supervise and protect agriculture and trade. Nomads would raid cities • Early city dwellers fixed these problems in two ways: they organized a groups of government officials to act as supervisors, and they hired professional soldiers to guard their territory and trade routes. 3/17/2016 59 Living Together in Cities: Planning and Leadership 3/17/2016 60 Living Together in Cities: Levels of Social Standing • Ruling class: government leaders, military officials, priests, and often king, justified its power by means of religion. • Archaeological studies show evidence of levels of social standing. 3/17/2016 61 Living Together in Cities: Invention of Writing • Many archaeologists think that writing originated with the records that priests kept of religious offerings. • First writings were pictographs— combination of marks and pictures 3/17/2016 62 Systems of Values 3/17/2016 • Among the materials recorded by the priesthoods in early civilizations were myths—traditional stories-explaining how the world was formed, how people came into being, and what they owed their creator. • Creation myths, found in every civilization, are often examined by historians for evidence of a people’s 63 customs and values. Systems of Values • The Sumerians of the Tigrus and Euphrates River Valley wrote their myth of creation on clay tablets 3/17/2016 64 In Class Discussion • List at least four main ideas about the first civilizations 3/17/2016 65
