Drama reconstruction – Procession on mountainside/battle
Voiceover: Modern history has been shaped by conquest – the
conquest of the world by Europeans. The Conquistadors led the way.
A few hundred men came to the New World and decimated the native
population. The secret of their success? Guns, Germs and Steel.
Ever since, people of European origin have dominated the globe,
with the same combination of military power, lethal microbes and
advanced technology. But how did they develop these advantages in
the first place? Why did the world ever become so unequal? These
are questions that Professor Jared Diamond has spent more than 30
years trying to answer. One of the most original thinkers of our
age, Diamond has traveled the world looking for clues. He set himself
a daunting task – to peel back the layers of the past, and
explore the very roots of power in the modern world.
Jared at Blacksmiths
Jared Diamond: Whatever I work on for the rest of my life, I can
never work on questions as fascinating as the questions of guns,
germs and steel, because they’re the biggest questions of
Voiceover: What separates the haves from the have nots? How have
guns, germs and steel shaped the history of the world?
Titles: Episode 1: Out of Eden
Jared in boat on river, photographing birds
Voiceover: Jared Diamond’s quest to uncover the roots of
inequality began in the rainforests of Papua New Guinea.
Jared in rain forest with Papua New Guineans
Voiceover: Diamond is a professor at UCLA in Los Angeles. He’s
a biologist by training, a specialist in human physiology. But his
real passion has always been the study of birds.
Jared Diamond: I love watching birds in this place. I began watching
birds when I was seven years old in the United States. Then it was
just a matter of identifying them. I came here when I was 26 years
old, to New Guinea, and it was love at first sight.
Voiceover: Diamond has been making regular trips to New Guinea ever
since..and is now a leading expert on the bird life of the island.
But in the course of his fieldwork he’s become just as curious
about the people of New Guinea.
Jared Diamond: Over the years I’ve gotten to know and like
thousands of New Guineans. I’ve learned several of the languages,
and much of what I know about birds I picked up from them.
Voiceover: There have been people living in New Guinea for at least
40,000 years – much longer than on the continents of North
and South America. They’re among the most culturally diverse
and adaptable people in the world. So why are they so much poorer
than modern Americans? The question was put to Diamond bluntly by
a man called Yali, whom he met on a beach more than 30 years ago.
Yali Voiceover: Why you white man have so much cargo and we New
Guineans have so little?
Jared Diamond: Yali’s question really threw me. It seemed
so simple and obvious, and I thought it must have a simple and obvious
answer, but when he asked me, I had no idea what that answer was.
Yali Voiceover: Why you white men have so much cargo and we New
Guineans have so little?

Archive: B&W footage New Guineans carrying goods and white
Voiceover: New Guineans use the word cargo to describe the material
goods first brought to their country by Westerners. Cargo was regarded
by many as evidence of the white man’s power. It was treated
with an almost religious reverence. For their part, Western colonials
typically believed that power was determined by race. They saw themselves
as genetically superior to the native population. To them, it was
only natural that they should have so much cargo and New Guineans
Jared Diamond: To me, any explanation based on race is absurd. I
know too many really smart New Guineans to believe there’s
anything genetically inferior about them. It’s their ingenuity
and their quickness to learn that have always impressed me. They
can go empty-handed into some of the most difficult environments
on earth, knock up a shelter in a few hours and survive. I wouldn’t
know where to start. In this environment I’d be helpless without
them. So why didn’t these ingenious people invent metal tools,
or build great cities, or develop any of the other trappings of
High-speed shots New York City street scenes
Jared Diamond: The world that I’m from is so different. The
modern U.S. is the richest, most powerful state on earth. It’s
crammed with more cargo than most New Guineans could ever imagine.
But why? That’s what Yali wanted to know. How did our worlds
ever come so different?
Ancient Egyptian structures
Voiceover: Diamond realized that Yali’s question was far
bigger and more complex than it first appeared. It was really about
the roots of inequality – a question as old as human history itself.
Greek and Roman ruins, Mayan sculpture
Jared Diamond: Why, since ancient times, have some societies progressed
faster than others? What allowed the Egyptians to build great pyramids
while most of the world was still scratching out a living? How did
the Greeks ever develop such an advanced civilization? Or the Romans?
Or the Maya?
Jared Diamond: All great civilizations have had some things in common
– advanced technology, large populations, and well-organized
workforce. If I could understand how those things came into existence,
then I’d understand why some people marched faster than others
during the course of history.
Globes in darkened room, pan across to Jared reading
Voiceover: Diamond set out to explore the division of the world
into haves and have nots. It was a massive challenge that few scholars
would have dared take on. He was a scientist, not a historian. How
could he possibly solve the great puzzles of human history?
Graphic showing earth from space
Voiceover: To understand where inequality came from, Diamond needed
to identify a time before inequality, when people across the world
were living more or less the same way. He had to turn back the clock
thousands of years, back before the first civilizations. Back into
prehistory. 13,000 years ago, the ravages of the last Ice Age were
over. The world was becoming warmer and wetter. One area where humans
were thriving was the Middle East.13,000 years ago, the Middle East
was far less arid than today, with more forests, trees and plants.
People here lived like people everywhere at this time – as
hunter/gatherers in small, mobile groups. They were frequently on
the move, making shelters wherever they could find animals to hunt
or plants to gather. They’d live in these shelters for weeks
or months at a time, as long as they could keep feeding themselves.
But as seasons changed and animals migrated, they’d move on,
to the next valley or ridge, looking for new sources of food.
New Guineans and Jared hunting in rainforest
Voiceover: One of the few places on earth where it’s still
possible to find people hunting and gathering is the rainforest
of Papua New Guinea.
Jared Diamond: Instead of just reading about this lifestyle in archaeological
books, I’ve been lucky enough to witness it first hand, to
see for myself how we all lived 13,000 years ago, and how we found
food. To catch an animal requires skill, stealth, and encyclopedic
knowledge about hundreds of animal species. You have to be pretty
smart to be a hunter.
Early Middle Eastern people hunting deer
Voiceover: 13,000 years ago, people in the Middle East hunted in
the same way, tracking down whatever game they could find. But the
fundamental problem with hunting is that it’s never been a
productive way to find enough food. It takes time to track each
animal. And with a bow and arrow, there’s no certainty of
how the hunt will end.
Jared learning to fire arrows with New Guineans
Voiceover: Because hunting is so unpredictable, traditional societies
have usually relied more on gathering. In this part of Papua New
Guinea, the gathering is done by women. An important source of food
here is wild sago. By stripping a sago tree they can get to the
pulp at the centre, which can be turned into dough and then cooked.
Although it’s physically harder work, gathering is generally
a more productive way of finding food than hunting. But it still
doesn’t provide enough calories to support a large population.
Jared Diamond: This jungle around us, you might think it’s
a cornucopia, but it isn’t. Most of these trees in the jungle
don’t yield, don’t give us anything edible. There were
just a few sago trees, and the rest of these trees don’t yield
anything that we could eat.
And then sago itself has got limitations – one tree yields
only maybe about 70 pounds of sago. It takes them three or four
days to process that tree, so it’s a lot of work really for
not a great deal of food, plus the sago starch is low on protein,
and also the sago can’t be stored for a long time. And that’s
why hunter/gatherer populations are so sparse. If you want to feed
a lot of people, you’ve got to find a different food supply,
you’ve got to find a really productive environment, and it’s
not going to be a sago swamp.
Cereal crop being harvested
Voiceover: In the Middle East, there were very different plants
to gather. Growing wild between the trees were two cereal grasses,
barley and wheat. Far more plentiful and nutritious than sago. These
simple grasses would have a profound impact, setting humanity on
the course towards modern civilization. But it would take a catastrophic
change in the climate before this would happen.
Graphic showing earth from space with ice spreading
Voiceover: 12,500 years ago, the world’s climate became highly
volatile. The long-term thaw that had brought about the end of the
last ice age suddenly went into reverse. Global temperatures dropped,
and ice age conditions returned.
Rocky mountainsides with people standing and walking
Voiceover: The world became colder and drier. The Middle East suffered
an environmental collapse. Animal herds died off. So did many trees
and plants. The drought lasted for more than 1,000 years. People
were forced to travel farther and look much harder for any source
of food. But despite the conditions, they would somehow survive,
even prosper. Here in the Middle East, a new way of life would come
into being, one that would change the face of the earth.
SUV driving through desert to dig site, Ian Kuijt driving
Voiceover: Ian Kuijt is a Canadian archaeologist who specializes
in the Stone Age history of the Middle East. His work has focused
on a site in the Jordan Valley, near the Dead Sea – a place
known as Dhra'. Kuijt is a co-director of the dig, and works with
an international team of archaeologists. They’ve uncovered
the remains of ancient dwellings that were clearly more sophisticated
than any hunter/gatherer shelters. They believe this was a small
village, one of the earliest permanent villages anywhere in the
world. People were starting to put down roots.
Dr Ian Kuijt, Notre Dame University: What we would have had is this
village of, I don’t know, 40, 50 people, living in the same
place. We would have had a series of oval huts that would have been
partially cut into the ground, and these would have been very much
the, the first time people settled down and lived in communities
in a really extensive way.
Voiceover: When they radiocarbon dated the site, they discovered
that the village first emerged 11,500 years ago – at the same
time as the end of the drought in the Middle East. But how was it
possible to feed an entire village if times were so hard? After
four years of digging at Dhra’, the archaeologists believe
they have an answer. It lies in this unique structure.
Ian Kuijt: What you can see here is the outline of a mud wall coming
all the way round here, and then inside we have a series of upright
stones that have been chipped in such a way where you can see a
notch on them, and there would have been a series of beams over
the top of that, with a floor across it, and basically you would
have had a dry, humidity-controlled environment, where they could
take grain, they could take any plants, they could dry them out,
put them in here, protect them from insects, protect them from moisture,
protect them from water percolating through. What that ends up being
from our perspective is probably the world’s first granary
in some form – a place where they were able to store food
at a particular location on a year-round basis.
Computer Generated Image showing likely construction of original
building, people harvesting grain, mountain-sides, people sowing
Voiceover: The team at Dhra’ believes the granary was an
oval-shaped mud wall building at the centre of the village; a place
where grain could be stored collectively. And the grains that were
being stored were primarily wheat and barley. While other plants
were no longer available, these cereal grasses were hardy enough
to survive, and durable enough to be stored for years. But if this
was a time of scarcity, how was there enough grain to fill a granary?
The answer suggests a radical shift in human behavior. At some point
during the drought in the Middle East, people started growing their
own food. Unable to maintain a mobile way of life, they would have
stayed close to any source of water they could find, and planted
new fields of wheat and barley around them.
Ian Kuijt: Rather than just following food sources around different
locations, for the first time what people start to do is that they
bring these resources back to them. Not just as harvested food,
but they’re bringing them as seeds, and they’re growing
them next to their village, and that’s the first time, really
this is the first time we see this anywhere in the world.
Voiceover: The Stone Age people of the Middle East were becoming
farmers – the first farmers in the world.
High-speed footage of plants growing
Voiceover: Without realizing it, these new farmers were changing
the very nature of the crops around them. With every round of planting
and harvesting, they’d favor ears of wheat and barley whose
seeds were the biggest, tastiest or easiest to harvest. Traits that
were useless to the plant in the wild thrived under human cultivation.
Ian Kuijt: They interrupted the cycle. They interrupted the normal
environmental cycle and started to select these individual plants
and basically rewarding those that were going to be most profitable
to them, and so even though it was accidental, once that whole process
started, people were starting to control nature.
Crop laboratory with scientists working and early Middle Eastern
Voiceover: The way crops are changed by human interference is known
as domestication. Today it happens in research labs, with scientists
selecting genes and breeding crops to be ever more useful to humans.
It’s a very precise, deliberate process. But not so different
from what the first farmers were doing unconsciously, thousands
of years ago in the Middle East.

Jared Diamond: The transition to farming was clearly a decisive
turning point in human history. People who remained hunter/gatherers
couldn’t produce anywhere near as much food as farmers, and
also couldn’t produce much food that could be stored. They
were always going to be at a chronic disadvantage. Now I needed
to know where else in the ancient world people had become farmers.
If I could establish links between the spread of farming and the
spread of civilization, I’d be well on my way to answering
Graphic showing earth from space with areas of crop cultivation
Voiceover: There are only a few parts of the ancient world that
developed farming independently. Not long after the Middle East
came China, where people grew another high yield cereal grass –
rice. Pockets of farming also emerged in the Americas, based on
corn, squash and beans. Later, in Africa, people farmed sorghum,
millet and yams. And in most places where farming emerged, a relatively
large, advanced civilization followed. But there was an exception
to the rule. An area where farming didn’t bring the same benefits
– the highlands of New Guinea.
View of New Guinea from plane, New Guinean farmers working
Voiceover: For 50 years after Westerners colonized New Guinea,
they thought the highland valleys in the interior were uninhabited.
In fact, they were the most densely populated part of the island,
with one of the oldest systems of farming in the world. Archaeologists
now believe that people have been farming here for almost 10,000
years – almost as long as the people of the Middle East.
Jared with crowd of New Guineans, New Guinean farmers working
Jared Diamond: It’s amazing to think that these people, Yali’s
people, were some of the earliest farmers in the world. But if they
were farmers, why weren’t they propelled down the same path
towards civilization as the people of the Middle East or China or
Central America? Why didn’t they end up producing their own
Voiceover: New Guinea farmers themselves were surely no less talented
than farmers anywhere else in the world. So what was the difference?
Jared Diamond: Highland agriculture was based on crops like these
taro roots, which are very different from cereal crops. Taro is
much more work. You’ve got to plant it one by one, unlike
wheat where you throw your hand and spread the seed, and these New
Guinea crops can’t be stored for years the way wheat can –
they rot quickly, they have to be eaten in a short time. They’re
also low in protein compared to wheat, so these farmers of the New
Guinea highlands suffered from protein deficiency.
People tending banana crops, giant spiders
Jared Diamond: There’s not much protein to be gotten from
New Guinea’s other crops, either. People here farm local varieties
of bananas, but although bananas are rich in sugar and starch, like
taro they’re low in protein. In fact, people in the highlands
have so little protein that sometimes they eat giant spiders to
supplement their diet.
Jared studying in room
Jared Diamond: I’d reached a moment of realization. Farming
was clearly crucial to the story of human inequality. But, just
as important was the type of farming. People around the world who
had access to the most productive crops became the most productive
Voiceover: Ultimately it came down to geographic luck.

Early Middle Eastern crop harvesting
Voiceover: It’s an audacious idea that the inequalities of
the world were born from the crops we eat. According to Jared Diamond,
Americans have had an advantage over New Guineans because for centuries
they’ve grown crops that are more nutritious and productive.
Crops like wheat, which provides about a fifth of all the calories
they eat. The wealth of modern America could never have been sustained
by taro and bananas. But Diamond’s idea seems almost too simple.
Could plants alone really have the power to shape the course of
human history? Or was there something else at play? Another reason
for the division of the world into haves and have nots?
Woman grinding corn, people harvesting crops, goats being herded
Voiceover: By 9,000 years ago, the first settlements in the Middle
East were giving way to much larger villages. People were only able
to live on this scale by becoming more productive farmers. They
were surrounded by fields of domesticated wheat and barley,
but by now they also had another steady source of food.
Dr Louise Martin, Institute of Archaeology, University College London:
What we see happening about 9,000 years ago is a remarkable transformation
in the way that humans are interacting with animals. We begin to
see a process of animal domestication, by which we mean humans were
controlling where they were moving, they were controlling their
feeding, and they were controlling their breeding. Instead of having
to go out to hunt, you have a dependable meat supply on the hoof,
year-round, around your site, rather than being subject to seasonal
variations in wild game.
Goats being milked and combed
Voiceover: As well as meat, animals could be used for their milk,
providing an ongoing source of protein. Their hair and skins could
be used to make clothes for extra warmth. Over time, domestic animals
became an integral part of the new agricultural way of life.
Goats being watched, people harvesting crops
Louise Martin: We know that the communities which first started
to have domestic animals already had cereal crops, so they were
cultivators, and the combination of these particular animals and
plants becomes an extremely attractive package, in that they’re
complementary. After the harvest period, animals could be turned
out on the stubble, and they can actually eat the remains of the
cereal crop harvest. In their turn, animal dung can be used to provide
sort of a fertilizer for the cereal crops as well, the crops, so
the whole, the whole package, you know, is seen to be mutually beneficial,
both for the animals and the plants and of course for the humans.

Voiceover: Goats and sheep were the first animals to be domesticated
in the ancient world, and were eventually followed by the other
big farm animals of today. All of them were used at first for their
meat, but they all prove useful in other ways, especially with the
invention of the plough. Before the industrial revolution, beasts
of burden were the most powerful machines on the planet. A horse
or an ox, harnessed to a plough, could transform the productivity
of the land, allowing farmers to grow more food and feed more people.
In New Guinea and many other parts of the world, people never used
ploughs because they never had the animals to pull them.
Pigs, New Guinean men carrying poles and farmers working
Jared Diamond: The only big domestic animal in New Guinea was the
pig, and it wasn’t even native – it came in from Asia a few
thousand years ago – while Europe and Asia had not only pigs
but also cows, sheep, goats, horses, buffalo, camels and so on.
Now pigs do give you meat, but pigs don’t give you the other
products that you get from those European and Asian animals.
Voiceover: Pigs don’t give you milk, or wool, or leather
or hides, and most important of all, pigs can’t be used for
muscle power – pigs don’t pull ploughs or pull carts.
The only muscle power in New Guinea was human muscle power.
Jared Diamond: Even today, there are no beasts of burden in New
Guinea, and almost all of the farm work is still done by hand. But
if farm animals were so useful, why didn’t New Guineans domesticate
any of their own? I decided to add up all the animals in the world
that have ever been domesticated, and I was amazed by what I found.
Animals of all kinds
Archive: B&W footage people chasing elephants
Voiceover: There are nearly two million known species of wild animals,
but the vast majority has never been farmed. Most insects and rodents
are of no practical use to humans, and not worth the effort of farming.
Some birds, fish and reptiles have been domesticated, but most are
simply impractical to farm. So are most carnivores, not because
but because you’d have to grow other animals just to feed
them. The best animals to farm are large, plant-eating mammals.
And over the years, humans have probably tried to domesticate all
of them, usually without success. Despite repeated efforts, Africans
have never domesticated the elephant.
Elephants at work
Voiceover: In South Asia, some elephants are used as work animals.
But they’re not farmed for the purpose. Instead, each elephant
is caught in the wild and then tamed and trained. It doesn’t
make economic sense to farm an animal that takes some 15 years to
mature and reach an age where it can start reproducing.
Horses in corral, Goats, Sheep, Camels, Water buffalo, Cattle
Louise Martin: Animals which made suitable candidates for domestication
can start giving birth in their first or second years. They will
have one or maybe two offspring a year, so they’re productivity
is actually high. Behaviorally they need to be social animals, meaning
that the males and the females and the young all live together as
a group, and they also have an internal social hierarchy, which
means that if humans can control the leader, then they will also
gain control over the whole herd or whole flock.
Wild animals, Zebra
Voiceover: There is another crucial requirement for a domestic
animal. It needs to get along with humans. Some animals don’t
have the temperament to live on a farm. A zebra could be an ideal
domestic animal, potentially as useful as a horse. But evolving
in the midst of Africa’s great predators, zebras have become
flighty, nervous creatures. They have a vicious streak that humans
have been unable to tame. That may be why zebras have never been
harnessed to a plough or ridden into battle.

Graphic showing earth from space with highlighted areas
Jared Diamond: I counted up 148 different species of wild, plant-eating
terrestrial mammals that weighed over 100 pounds, but of those 148,
the number that has ever been successfully farmed for any length
of time is just 14.
Voiceover: Goats, sheep, pigs, cows, horses, donkeys, Bactrian camels,
Arabian camels, water buffalo, llamas, reindeer, yaks, mithans,
and bali cattle. Just 14 large domestic animals in 10,000 years
of domestication. And where did the ancestors of these animals come
from? None was from New Guinea, or Australia. Or Sub-Saharan Africa,
or the whole continent of North America. South America had the ancestor
of just one large domestic animal; the llama. The other 13 were
all from Asia, North Africa and Europe. And of these, the big four
livestock animals; cows, pigs, sheep and goats, were native to the
Middle East. The very same area that was home to some of the best
crops in the world was also home to some of the best animals. Little
wonder that this area became known as the Fertile Crescent.
Sky, tilt down to village ruins with man walking, Man sowing seed,
Goats, Guar site with ruins
Voiceover: The people of the Fertile Crescent were geographically
blessed, with access to some of the best crops and farm animals
in the ancient world. It gave them a huge head start. What had begun
with the sowing of wheat and the penning of goats was leading towards
the first human civilization. The archaeological site of Guar in
Southern Jordan is 9,000 years old. But it has all the hallmarks
of a town. A few hundred people lived here, in rows of houses that
were a wonder of technology.
Dr Mohammad Najjar, Department of Antiquities, Jordan: Every time
I come here, I’m amazed by what those people were doing. Some
of the houses have a kind of air conditioning, a, this window here
is for, to control the air coming from the street inside the house,
and the houses, the walls and the floors of the houses from the
inside at least, were covered with plaster.
People plastering walls
Mohammed Najjar: So people were moving to a concept of homes. It’s,
it’s not a place just to sleep, it is a proper home, and people
started to decorate the houses from the, from the inside, and people
were starting to invest in their homes, because if we are talking
about plaster, it is time-consuming, it’s effort-consuming
– it’s very expensive to have plastered house.
People sowing seeds, making cement, weaving, making plaster
Voiceover: As villages grew bigger, there were more people to work
on the land. More people could produce more food more efficiently
– enough to support specialists within the community. Freed
from the burden of farming, some people were able to develop new
skills, and new technologies. Making plaster from limestone was
a major technological breakthrough. The stones had to be heated
for days at a time, at a temperature of 1,000 degrees. It may seem
insignificant today, but understanding how to work with fire was
the first step towards forging steel – a technology that would
transform the world.

Jared Diamond: When I first came to New Guinea in the 1960s, people
were still using stone tools like this axe in parts of the island,
and before European arrival, people were using stone tools everywhere
in New Guinea. So why didn’t New Guinea develop metal tools
by itself? And eventually I realized that to have metalworking specialists
who can figure out how to smelt copper and iron, requires that the
rest of the people in the society who were farmers, be able to generate
enough food surpluses to feed them.
Voiceover: But New Guinea agriculture was not productive enough
to generate those food surpluses, and the result was no specialists,
no metalworkers, and no metal tools.

Voiceover: The way of life in New Guinea was perfectly viable.
It had survived intact for thousands of years. But according to
Diamond, people didn’t advance technologically because they
spent too much time and energy feeding themselves. And then Westerners
arrived, and used their technology to colonize the country.

Voiceover: Yet for all its advantages, the Fertile Crescent is
not the powerhouse of the modern world, nor is it the bread basket
it once was. How did it lose its head start?
Voiceover: Within 1,000 years of their emergence, most of the new
villages of the Fertile Crescent were abandoned. Ironically, the
region had a fundamental weakness. Despite having some of the most
nutritious crops on the planet, its climate was too dry, and its
ecology too fragile, to support continuous intensive farming.
Arid landscape, Jordanian village site
Mohammed Najjar: People were destroying the environment. The waters
had been over-exploited, the trees had been cut, and this is what
when, when, when you, when you face the, the end, I mean you are
facing the wall. You will end with landscape like that, mean with,
with few trees, with no grass, and with less water. So what we are
looking at today is the outcome of over-exploiting the environment.

Voiceover: Unable to farm their land, entire communities were forced
to move on. The advantages they’d accrued from centuries of
domestication might have been lost. But again, geography was on
Graphic showing earth from space, with highlighted areas and arrows
Jared Diamond: The Fertile Crescent is on the middle of a huge
land mass, Eurasia. There were plenty of places for farming to spread,
and crucially, many of those places were to the east and west of
the Fertile Crescent, at roughly the same line of latitude.
Computer Generated Image – landscape with arrows
Jared Diamond: Why’s that so important? Because any two points
of the globe that share the same latitude automatically share the
same length of day, and they often share a similar climate and vegetation.
Crops or animals domesticated in the Fertile Crescent were able
to prosper at other places along the east/west axis of Eurasia.
Wheat and barley, sheep and goats, cows and pigs all spread from
the Fertile Crescent, east towards India and west towards North
Africa and Europe. Wherever they went they transformed human societies.

Voiceover: The same is true of European civilization. From ancient
times until the Renaissance, the crops and animals of the Fertile
Crescent fed the artists, inventors and soldiers of Europe. In the
16th century, the same crops and animals were taken by Europeans
to the New World. At the time there was not a single cow or ear
of wheat in all the Americas. Now there are 100 million cattle in
the US alone. And Americans consume 20 million tons of wheat a year.

Voiceover: There are some who think Jared Diamond’s argument
is too neat and easy. Can the distribution of wealth and power really
be reduced to cattle and wheat? What about culture, politics and
religion? Surely they’ve been just as important? Diamond’s
been criticized for being too deterministic, for ignoring the part
people have played in shaping their own destiny.
