The themes of the course include emerging human biological and cultural diversity as well as our similarities, the importance of climatic and environmental change, and the importance of seeing prehistory as a tale of people and their beliefs, not just archaeological sites.
Evidence of human origins dates from between 6 million and 3 million years ago. What anatomical and behavioral changes occurred among hominids across this vast expanse of time? What fossil forms define the earliest stages of human evolution?
The earliest tool-making hominids appeared between 3 million and 2 million years ago. Evidence from Louis and Mary Leakey's excavations at the famous Olduvai Gorge in Tanzania suggests that Homo habilis, the first toolmaker, used these stone implements as aids in scavenging and foraging.
Until about 730,000 years ago, world climate seems to have been fairly stable. Since then, climate shifts including Ice Ages have played a major role in human biological and cultural evolution, as we can see by considering theories of how humans first moved from Africa to Asia.
Europe seems to have been colonized only about 800,000 years ago—the dating is controversial. Archaeological research indicates people who lived a flexible and highly mobile life, but with cognitive and linguistic abilities that seem no match for those of modern humans.
This lecture clears away many of the misleading stereotypes about these nimble, efficient hunters who used simple but versatile tools in order to adapt impressively to the harsh climate of late Ice Age Europe and Eurasia.
You learn the compelling evidence from molecular biology that shows the origins of Homo sapiens sapiens, modern humans, lie in tropical Africa more than 100,000 years ago.
The spread of modern humans from Africa into other parts of the world is one of the great dramas of prehistory. Why did it occur, and how did the Sahara Desert play a critical role in it?
The modern humans whom we call Cro-Magnons began to settle Europe 45,000 years ago. What was their crucial advantage over Neanderthals and other more archaic people? How did the Cro-Magnons bring together the material and spiritual worlds in ways never before seen?
What are the major features of Cro-Magnon mobile and cave art? How can we evaluate the various theories that have been put forward to explain what it means? How did the unique big-game hunting societies of the late Ice Age cope with their exceptionally harsh environment?
How and when the Americas were first settled is one of the most controversial questions in the entire field of prehistory. This talk outlines the basic issues and describes the two major competing hypotheses and the relevant evidence.
Hunter-gatherer societies began to flourish in North America about 14,000 years ago. They differed across regions, from the more densely peopled Eastern woodlands to the plains and the drier West, but all had elaborate beliefs reflected in art, burial customs, and ceremonial objects.
What vast climatic changes followed the end of the Ice Age about 10,000 years ago? How did a huge glacial-meltwater release in Canada affect the climate thousands of miles away in the Near East so profoundly that it may have sparked the development of agriculture?
What do excavations of early farming settlements at Abu Hureyra, Syria, and Jericho, Jordan, tell us about how the change from hunting and collecting to herding and farming took place?
Europe was a sparsely inhabited place until farmers began to spread rapidly across it from southeast to northwest beginning in about 7,000 B.C. Could the sudden formation of the Black Sea by the rising waters of the Mediterranean have been the trigger for this diffusion?
Rice has been grown in the Yangtze Valley of southern China since before 7,000 B.C., with millet farming in the Huangho Valley of the north about a millennium behind. But the many islands lying far off Asia could not be settled until root crops like taro and yams were domesticated.
The tale of how researchers traced domestic corn or maize to its wild Mesoamerican ancestor (a grass called teosinte) is one of the great detective stories in prehistory. Spreading both north and south, the farming of maize and associated crops such as beans would transform the landscape of both Americas.
The world's first civilizations appeared in southwest Asia about 5,000 years ago. What makes a "civilization," and what do all preindustrial civilizations have in common? What are the theories accounting for civilizations' expansions?
Evolving out of innovative farming societies that used irrigation to grow food between the Tigris and Euphrates Rivers, the small, competing city-states of Sumer were engaging in long-distance trade by 4000 B.C. and then became parts of a drive to form much larger empires.
The long, fertile, green ribbon of the Nile Valley is the setting for this most famous and flamboyant of ancient civilizations. Beginning, as had Sumer, in a series of smaller kingdoms along the river, Egypt's pyramid-building "Old Kingdom" flourished till 2180 B.C.
How did Mentuhotep, the politically gifted ruler who restored the Middle Kingdom, redefine his own role as pharaoh in order to achieve this? How did the New Kingdom of Ramses II and company redefine it as Egyptian military and imperial power grew?
In journeying north across the eastern Mediterranean from Egypt, we come across the Minoan civilization of Crete, whose site was the Palace of Minos at Knossos on that island. What made the religious beliefs at the heart of Minoan civilization so different from those found in other early states?
Among the high points of this talk is the discussion of the remarkable Uluburun shipwreck, an amazing 1984 find off the coast of Turkey that contains a rich cargo drawn from nine regions and gives us a superb window on the burgeoning world of international trade c. 1300 B.C.
This civilization rose in the Indus Valley of what is now Pakistan before 2500 B.C. In a way, it was a result of the rise of cities in Mesopotamia because trade with that area seems to have stimulated the rise of cities along the Indus. Were Harappan religious beliefs the ancestors of Hinduism?
Starting with the Harappan collapse (c. 1700 B.C.), we enter the Vedic period, when far-reaching cultural, religious, and technological changes swept South Asia, culminating in the discovery of the monsoon wind cycle (c. 100 B.C.), which opened the door to travel and trade across the Indian Ocean and beyond.
Ranging over sites on the continent from the caravan routes of Sudan to the great cattle-raising kingdoms of the south-central plateau around Zimbabwe, this talk shows how Africa played a major role in the Indian Ocean world during the first millennium A.D.
Here we explore the increasingly complex Longshanoid cultures that grew up over a wide swath of northern China after 3000 B.C. What do we know about the three early dynasties—Xia, Shang, and Zhou—and the realms over which they presided?
The Western and Eastern Zhou periods were times of endemic warfare until Emperor Qin Shihuangdi unified China in 221 B.C. The Han Dynasty brought China into contact with the West via the Silk Road, and with India by connecting to the ancient monsoon-wind routes of Southeast Asia.
While these civilizations possess indigenous roots, it is also true that China and India had a large impact on them. The famous sites of Angkor Wat and Angkor Thom give us insight on the uniquely centripetal Khmer civilization and its notions of divine kingship.
With this talk we change hemispheres to examine the chiefdoms and states of the Americas before Columbus. Topics include the Pueblo sites of Chaco Canyon and Mesa Verde, the moundbuilders of the Eastern woodlands, and the great chiefdoms of the Mississippian tradition.
We explore the rise and decline of the Maya, who ran the greatest lowland civilization of pre-Columbian times, analyze their origins, study their central institutions such as kingship, describe key Maya sites such as Nakbe and El Mirador, and examine the reasons for their collapse c. A.D. 900.
Like the lowlands, the highlands of Mesoamerica were also a cradle of civilizations beginning around the first millennium B.C. The last and most famous was that of the Aztecs, who rose from obscurity to become masters of Mesoamerica in just two dizzying centuries, only to fall themselves before a tiny band of Spanish conquistadors.
This civilization developed between two poles: one on Peru's North Coast, the other in the south-central Andes. Around the former grew up the remarkable Moche state (c. 200 B.C. to A.D. 600), which provides a case study of how a civilization can be overcome by natural disasters.
The Inka were imperial conquerors who took over smaller kingdoms in both the Andean highlands and Peru's north coast sometime after A.D. 1000. Aside from their passion for organization, what institutions fueled the Inkas' endless conquests? And how did a tiny band of Spanish adventurers seize this vast empire so quickly in 1532?
Here you cast a backward glance over the four main chapters of human prehistory—the archaic world, the appearance and spread of modern humans, food production, and the development of states. Why does knowledge of this matter in today's world? How does it strengthen our understanding of the human condition?
