Out of Africa: First Migrations
1.1
Modern humans first appeared in East Africa and lived only by gathering, hunting, and fishing for over 95 percent of our history.
Humans moved into Eurasia first, then reached
Australia
about 60,000 years ago by boat, which was a first in human history.
Aboriginal Australians kept a foraging life into modern times and explained the world through the
Dreamtime
.
People reached the Americas at least 15,000 years ago. The
Clovis culture
spread across North America, and a
megafaunal extinction
followed, caused by hunting, climate change, or both.
The last big migration was the
Austronesian migrations
, a fast sea-borne settlement of the Pacific islands and Madagascar by people who already farmed.
Carved
Venus figurines
found across Eurasia hint at shared ideas over a huge area.
The Ways We Were
1.2
Foraging bands were small and moved often, so people owned little and shared a lot.
There were no kings or full-time specialists. Men and women had fairly equal status, though not perfect equality.
Some scholars call these groups
"the original affluent society"
because people met their needs with modest work and had leisure time.
Religion was led by part-time
shamans
. Among the San, the
trance dance
was used to heal and protect the group.
Humans changed their environments early, using fire and hunting large animals.
Settling Down: The Great Transition
1.3
As the Ice Age ended, some areas became rich in wild food, so some foragers stayed in one place. This is
Paleolithic settling down
.
Settled foragers had larger populations, stored food, more property, and more inequality.
Göbekli Tepe
in Turkey shows that foragers built huge stone monuments before farming existed.
Breakthroughs to Agriculture
1.4
Farming began separately in several regions at roughly the same time, about 12,000 to 4,000 years ago.
Warming after the Ice Age let populations grow. When food ran short, people began deliberately planting crops and taming animals.
The
Fertile Crescent
had many easy-to-domesticate plants and animals, so farming developed quickly there.
In Mesoamerica, farming came slowly. People spent centuries breeding
teosinte
into maize, and there were few large animals to tame.
The Globalization of Agriculture
1.5
Farming spread in two ways:
diffusion
of ideas and crops between neighbors, and the migration of farming peoples.
The
Bantu migration
carried farming, and later iron, across much of Africa south of the Sahara.
Some foragers resisted farming where their way of life still worked well, such as Australia and the west coast of North America.
Over time, foragers were pushed aside.
Ishi
, the last of the Yahi people, is a symbol of that loss.
Farming brought larger populations, harder work, new diseases from animals, and new technologies like pottery and metalworking.
Social Variation in the Age of Agriculture
1.6
The
"secondary products revolution"
found new uses for animals, like milk, wool, and pulling plows.
Pastoral societies
herded animals in lands too dry or cold to farm. They were often mobile and traded with or raided farmers.
Many agricultural village societies, like
Banpo
in China and
Çatalhüyük
in Turkey, had no rulers or deep inequality.
Chiefdoms
had leaders with inherited status who redistributed goods but had little power to force obedience.
Farming slowly increased inequality and the power of men over women in many places.
