STUMBLING
INTO DOMESTICATION
In his lecture, Four
Domestications, James
Scott described four turning points that radically changed the course of
the human saga — the domestication of fire, plants, animals, and ourselves. We domesticated ourselves by radically
changing the way we lived, in order to protect and nurture the survival and growth
of crops and herds. We controlled their
lives, and they controlled ours. Many
tasks had to be performed at specific times for optimal results — tilling,
planting, weeding, watering, harvesting, etc.
Herders also fine-tuned their ongoing schedules and activities for the
benefit of their livestock.
We’ve already looked at the domestication of fire, and how
this superpower radically altered the human saga. It enabled tropical humans to survive in chilly
non-tropical regions (snow country), colonize the planet, and eventually become
participants in monstrous fire-breathing industrial civilizations. This chapter will focus on plant and animal
domestication, which mostly began within the last 13,000 years, and fired up
the turbochargers for our high-speed one-way rocket ride into the unknown.
Supply
and Demand
Mother Africa was the homeland where hominins first evolved maybe
six million years ago. Experts do not
agree on when humans first emerged.
Estimates range from maybe 250,000 to 400,000 years ago. For almost the entire human saga, our
ancestors were nomadic foragers — hunters and gatherers. Around 60,000 years ago, some pioneers
decided to see the world, and began exploring the tropics of southern Asia, on
a path toward Australia.
Around 42,000 years ago, humans were present up north in Europe,
a region with a temperate climate. It
was a major shift, moving outside of the tropical climate for which evolution
had fine-tuned us. The curiosity of
these explorers helped to accelerate our journey to a stormy future. Long term survival in a non-tropical region required
loads of radical innovations.
As mentioned earlier, William
Rees proposed two fundament ecological concepts. (1) Every species will expand to all
locations that are accessible to them, where conditions might allow their
survival. (2) When they expand into new
habitat, they will utilize all available resources, until limits restrain them.
Humans regularly bumped into limits as they colonized the
world, and cleverness often provided ways to bypass the obstacles. As long as wild foods were abundant, there
was no need to pursue farming or herding, which required far more time, difficulty,
and risk. Large game was our ancestors’
preferred food but, over time, hunting a bit too much could gradually deplete
the delicious herds. Efforts then had to
shift to class B and class C foods — small game, forest animals, waterfowl,
fish, shellfish, insects, and so on.
Barry
Cunliffe noted that as the last ice age weakened, the climate warmed, and
the more comfortable Holocene era began.
The forests of Europe were able to migrate northward from the
Mediterranean, displacing some tundra regions, and their megafauna residents. These forests were home to more solitary game
like aurochs, boars, elk, deer, and small animals. The total biomass of these forest animals was
only 20 to 30 percent of the biomass of the tundra herds they replaced. Reduced access to easy meat motivated lifestyle
changes. Folks learned that it was
easier to survive in locations close to coastlines, lakes, rivers, and
wetlands, where a year round supply of foods might be gathered. This new way of living apparently worked well
enough for a while.
Diana Muir wrote an environmental history of New England,
from the ice age to today. On the
tundra, folks hunted mastodons, horses, bison, and four species of
mammoths. There were sabertooth cats,
giant bears, giant beavers, and musk oxen.
As the climate warmed, forests spread northward. When the tundra megafauna declined, folks
hunted for deer, bear, beaver, moose, waterfowl, turkeys, and heath hens.
Rivers had huge runs of salmon, shad, and alewives. Stuff like acorns and shellfish were reserved
for famine food. As game got scarce,
shellfish became a mainstay. An adult
male would need 100 oysters or quahogs each day. Thousands were dug and smoked for winter
consumption, a tedious job. In the lower
layers of huge shell dumps were oyster shells 10 to 20 inches across (25 to 50
cm) — oysters 40 years old. In higher
levels, the shells got smaller and smaller.
Eventually, the seeds of domesticated corn (maize), squash,
and beans reached New England. Tribes
that pursued the new experiment could produce more food, and feed more people. When fields were first cleared, and the
virgin soil was still highly fertile, agricultural land might sometimes produce
a hundred times more food than an equal area of wild land used by
foragers. Of course, population pressure
is a predictable cause of social friction and bloody conflict. Because they had no livestock, they had no
manure to help conserve soil fertility, which declines over time, shrinking the
harvests.
The big picture here is an endless struggle for survival, in
which limits periodically stomped on the brakes, and cleverness often found new
ways to temporarily sneak around them.
Cleverness is not an all-powerful miracle-making magic wand. It also has limits, as the folks on Easter
Island discovered, when the last tree fell (whoops!). It’s not easy to cleverly sneak around food
scarcity. Options often boiled down to
starvation, mindful family planning, or a blind leap into the mysterious realm
of food production.
Cradle
of Civilization
Jared Diamond seriously wondered why some cultures could
remain rich and powerful for centuries, while many others rarely, if ever, had
an opportunity to sniff prosperity’s butt.
He invested a massive number of brain cycles in a quest to find answers. In 1987, he published his boat-rocking essay,
“The Worst Mistake in the History of the Human Race” [Link
or Link].
He wrote, “Archaeology is demolishing another sacred belief:
that human history over the past million years has been a long tale of
progress. In particular, recent
discoveries suggest that the adoption of agriculture, supposedly our most
decisive step toward a better life, was in many ways a catastrophe from which
we have never recovered. With
agriculture came the gross social and sexual inequality, the disease and
despotism that curse our existence.”
Ten years later, in 1997, Diamond published his classic, Guns,
Germs, and Steel, in which he presented a book length discussion of what he
had learned. Domestication emerged
independently in maybe nine locations around the world, but one region in
Eurasia played a starring role in influencing the chain of events that
eventually led to the bruised, beaten, and bleeding world outside your window.
It began one day, thousands of years ago, when some intrepid
pioneers happened to stumble into an amazing jackpot known as the Fertile Crescent,
the Cradle of Civilization. Gasp! It was as if their wildest dreams had come
true! The place was home to a great
abundance of wild game and plant foods — a heavenly paradise.
Life was grand for a while, but as the mobs grew in number,
they naturally smacked into more and more annoying limits. Cleverness inspired behaviors and illusions
that put folks on the treacherous path to farming and herding. This generated a surge of temporary prosperity,
while it permanently degraded the ecosystem.
Unfortunately, as centuries passed, the forests, soils, and
wildlife got rubbished. Paradise
deteriorated into depleted cropland, deserts, ancient ruins, and persistent
bloody conflicts. The Fertile Crescent
(like every other region), was not an ecosystem that could tolerate endless
agriculture. Diamond noted that farming
is a slow motion act of ecological suicide.
In 2002, five years after Guns,
Germs, and Steel, Diamond published a paper, “Evolution,
consequences and future of plant and animal domestication.” [Link] It presented some additional thoughts. The emergence of domestication, maybe 10,500
years ago, inspired tremendous changes.
It commenced in Eurasia, primarily in the Fertile Crescent and parts of
China, where the whims of “biogeographic luck” provided perfect conditions for seriously
dangerous mischief.
Not only were wild foods abundant, but an unusual number of
the plant and animal species possessed characteristics that made them suitable
for domestication. Despite centuries of trial
and error, clever humans have discovered that it’s impossible to domesticate
the vast majority of plants and animals.
To be suitable for domestication, species must have specific collection
of vulnerabilities.
For example, Diamond listed six obstacles that made it
impossible to domesticate most large animal species. Any one of these could prevent enslavement: (1)
a diet not easily supplied by humans, (2) slow growth rate and long birth spacing,
(3) nasty disposition, (4) reluctance to breed in captivity, (5) lack of
follow-the-leader dominance hierarchies, and (6) a tendency to panic in enclosures
or when faced with predators.
Diamond wrote that there are maybe 200,000 wild plant species
in the world, of which about 100 have been domesticated. The Fertile Crescent was home several wild
grasses that produced large cereal seeds (barley, einkorn, emmer, and spelt), a
rich source of carbohydrates. There were
also several varieties of pulses (peas, beans, and lentils) that provided
protein. In the whole world, purely by random
chance, the Fertile Crescent was the biggest treasure chest of future super
foods, both plant and animal. It was
essentially ground zero for the birth of civilization.
Globally, there are 148 species of large land-dwelling
mammalian herbivores and omnivores that weigh more than 100 pounds (45 kg). Sub-Saharan Africa is home to 51 of these
species, but none of them have been domesticated, because they luckily failed
to meet all of the six criteria for enslavement.
Of the 148 species, just 14 have been domesticated. Nine of the 14 only had regional
significance, but five species eventually became multinational superstars. The Fertile Crescent was home to four of the
five: the goat, sheep, pig, and cow (horses are the fifth) — an amazing
coincidence.
Of the 14 domesticated species, 13 of them originated in
Eurasia. Consequently, it’s no coincidence
that Eurasia played a primary role in the growth and spread of acute, highly
infectious, epidemic crowd diseases.
Farming and herding created communities of humans that lived in
unhealthy proximity to unnatural concentrations of livestock, poultry, rats, fleas,
mosquitoes, etc.
This encouraged a number of animal pathogens to adapt to
human hosts, including influenza, smallpox, tuberculosis, plague, measles, and
cholera. Diamond noted, “Such diseases
could not have existed before the origins of agriculture, because they can
sustain themselves only in large dense populations that did not exist before
agriculture, hence they are often termed crowd diseases.”
Nomadic foragers lived in small groups, enslaved no livestock
or poultry, and periodically moved their camps — a brilliant strategy for
avoiding diseases. On the other hand, humans
who lived in crowded villages and cities made tremendous advances in unsanitary
living. Crap and garbage was all over
the place, all the time. Rivers were the
source of drinking water, and the dumping place for sewage and filth. A later chapter will take a closer look at
disease.
Diamond noted four developments that dimmed the future for
hunter-gatherers, and encouraged the expansion of farming and herding. (1) Over time, hunting gradually made large
game less abundant. (2) We learned new
skills for collecting, processing, and storing foods. (3) Societies competed, spurring innovations
that improved our ability to survive.
(4) Growing populations required large-scale food production.
Folks who inhabited a paradise of plant and animal super
foods, learned lots of tricks for maximizing food production. Population surged, spurring the emergence of
cities and civilizations. Civilization
encouraged the development of stuff like metallurgy, industry, deforestation, soil
destruction, warfare, overcrowding, patriarchy, and slavery.
So, let’s rephrase what William Rees said about species. (1) “Every civilization
will expand to all locations that are accessible to them, where conditions
might allow their survival.” As they
expand, they will take along their livestock, crop seeds, weaponry, culture, technology,
religions, and diseases. (2) “When they colonize new
habitat, they will utilize
all available resources, until limits restrain them.”
Eurasia spans from Europe to China. The earliest centers of domestication were
the Fertile Crescent and parts of China.
State of the art food production provided both centers with powerful advantages
over their more humble neighbors. The
two centers became hubs for territorial expansion, and their languages, genes,
tools, and cultural influences have spread around the world.
This is a spooky story.
From the two hubs, the realm of farming and herding spread in many
directions. In the sixteenth century,
European travelers began noticing striking similarities in Indo-Aryan, Iranian,
and European languages. They appeared to
have a common ancestor. As the years
flowed by, scholars noticed that lots of other languages also had
similarities. A category was created to
name this large assortment.
Visit Wikipedia’s discussion of Indo-European
Languages. See the maps that show how
this language family spread across the Old World over time. Around 500 years ago, the age of global colonization
exported them to the Americas, Australia, Sub-Saharan Africa, and elsewhere. Today, the native language of about 46 percent
of humankind, is an Indo-European tongue.
Drop a pebble in a calm pool of water, and rings of ripples
spread in every direction. Diamond wrote
that humankind’s long and stormy story of food production, population growth, civilization,
and global domination, began in the Fertile Crescent. The pebble is called domestication.
Diamond lamented, “If they had actually foreseen the
consequences, they would surely have outlawed the first steps towards
domestication, because the archaeological and ethnographic record throughout
the world shows that the transition from hunting and gathering to farming
eventually resulted in more work, lower adult stature, worse nutritional
condition, and heavier disease burdens.”
Looking back from the twenty-first century, we can readily
see the many unnecessary wrong turns that our ancestors made. At the same time, we can observe the world
around us today, and readily see the catastrophes that those wrong turns
triggered. It’s heartbreaking. Cleverness without foresight is a deadly duo. It sure is an interesting time to be alive!

Hi Richard;
OK, I will never likely read as many books as you have along these lines, but will that stop me from recommending one more to you? Nope.
"The Dawn of Everything" by Graeber and Wengrow questions the conventional wisdom that we humans progressed in a linear fashion from hunter gatherer to agriculture, to cities, to empires, to nation states, to the pickle we are in now. They try to bring the most recent research in archeology to show that there were many instances where hunter gatherer cultures were quite stable and intentionally chose NOT to do agriculture, or other hierarchical patterns. I think they make some conclusions that might be a bit tenuous also, but the book is still useful to remind us that we still only kn ow part of the story.
Anyhoo, I know you are hard at work on your next book, but if you get a hankering to read some new material, I think you would enjoy this.
Hey! I just finished it last night, and from beginning to end, it didn’t impress me. I’m not a wizard at abstract thinking. These dudes were in ivory towers, a humans-only space station. The cultures they commented on were not located in ecosystems, nor affected by them. The focus was entirely on human ideas, human behaviors, and definitions of abstractions.
Cahokia died from mean leaders. Really? What about recent studies that found strong evidence of major floods in riverside sediments?
What about having a densely populated culture dependent on agriculture? Corn is a heavy feeder on soil fertility, and they had no livestock to produce manure.
Why was Cahokia surrounded by massive palisades, which they replaced three times over the years? Maybe they had some crabby neighbors.
Is it possible that a city of up to 30,000 discovered firewood limits? Lots of trees died to clear cropland, and provide heating and cooking fuel. Was it America’s first energy crisis?
Climate change is getting ready to blindside us. We’re approaching lots of resource limits. But collapse is off the radar. Why invest so much time and energy simply sorting and categorizing political systems? I’m not an abstraction dude. I think there are more important issues before us.
Most reviewers enjoyed the book more.
All the best!
