2 Guns, Germs, and Steel The Fates of Human Societies based on the book of the same name by Jared Diamond

3 The Books Major Question Peoples of Eurasian origin, especially those still living in Europe and Eastern Asia and in places where their cultures have spread, dominate the world in power and wealth. Other peoples have been decimated, subjugated and even exterminated by Eurasian colonists. WHY?

4 "In the 13,000 years since the end of the last Ice Age, …

5 …some parts of the world developed literate industrial societies with metal tools…

6 …other parts developed only non- literate farming societies…

7 …and still others remained societies of hunter-gatherers with stone tools…

8 Inequality and Extermination Those historical inequalities have cast long shadows on the modern world, because the literate societies with metal tools have conquered or exterminated the other societies."

9 Yalis Question Yali, a New Guinea politician asked "Why is it that you white people developed so much cargo and brought it to New Guinea, but we black people had little cargo of our own?"

10 Distribution of Wealth To rephrase, "why did wealth and power become distributed as they now are, rather than in some other way? Distribution of Wealth in the World

11 Common explanations Racial or genetic superiority? –No objective evidence for this theory

12 Common explanations Cold climate stimulates inventiveness? But Europeans inherited from warm climate peoples –agriculture, –wheels, –writing, and –metallurgy Japan inherited –Agriculture, metallurgy, writing –Industrial Revolution

13 Chapter 1 Up to the Starting Point

14 Cro Magnons Cro-Magnons moved into Europe 40,000 years ago. Tools, needles, fishhooks, harpoons, bows and arrows, sewn clothing, houses, carefully buried skeletons, art, hunting big prey. Displaced or killed off Neandertals

15 Spreading Out 40,000-30,000 years ago humans used watercraft to cross from Asia to Indonesia to Australia and New Guinea. This time period correlates to a massive extinction of large game in those places.

16 Large Game in Eurasia Diamond's theory is that large game survived in Eurasia because humans took a million years to develop tools and become lethal predators of large game, giving game time to adapt.

17 Spreading to the Americas By 20,000 years ago, humans learned how to survive in Siberia. This led to migration to Americas by 12,000 BC. It took 1,000 years for humans to cover both N. and S. America. Time period correlates to a massive extinction of large game in Americas: Horses, lions, elephants, cheetahs, camels, and giant ground sloths.

18 Chapter 2 A Natural Experiment of History

19 Chatham Islands In 1835, a seal hunting ship visiting the Chatham islands 500 miles off the coast of New Zealand brought the first news to New Zealand of islands where: "there is an abundance of sea and shellfish; the lakes swarm with eels; and it is a land of the karaka berry... The inhabitants are very numerous, but they do not understand how to fight, and have no weapons".

20 Chatham Islands

21 Maori of New Zealand Nine hundred of the native Maori people of New Zealand, armed with guns, arrived in the Chatham Islands announcing that the Chatham Islands people (the Moriori) were now their slaves, and killed those who objected.

22 Moriori Slaughter An eyewitness account said "The Maori commenced to kill us like sheep... We were terrified, fled to the bush, concealed ourselves in holes underground, and in any place to escape our enemies. It was of no avail; we were discovered and killed -- men, women, and children indiscriminately". Maori

23 Maori Explanation A Maori conqueror explained: "We took accordance with our customs and we caught all the people. Not one escaped. Some ran away from us, these we killed, and others we killed -- but what of that? It was in accordance with our custom".

24 Natural History Experiment This is a natural history experiment. Both the Maori and Moriori descended from the same Polynesian farmers who settled New Zealand.

25 Moriori But the Moriori, after moving to the Chatham islands hundreds of years earlier could not farm due to the cold climate, and became hunter/gatherers. They learned to live peacefully because their resources were so limited.

26 Maori The New Zealand Maori – continued farming – dense populations –more complex technology and political organization – ferocious wars: The difference was geography. Competing agricultural societies are prone to warfare

27 Chapter 3 Collision at Cajamarca

28 Conquest of the New World "The biggest population shift of modern times has been the colonization of the New World by Europeans, and the resulting conquest, numerical reduction, or complete disappearance of most groups of Native Americans "

29 Pizarro The Incas were conquered by the Spaniard Francisco Pizarro.

30 Pizarros Forces Pizarro had 168 soldiers. They were in unfamiliar territory, ignorant of the local inhabitants, were 1,000 miles away from reinforcements, and were and surrounded by the Incan empire with 80,000 soldiers led by Atahuallpa.

31 Guns, Germs and Steel Pizarro, however, had steel armor and swords, horse mounted cavalry, and guns (a minor factor).

32 Treachery The account of the capture of Atahuallpa is one of the most difficult passages you may ever read, due to the treachery employed by Pizarro, and the religious justification used. Of course, we also know that Pizarro collected a huge ransom for Atahuallpa in gold and silver, and then killed him anyway. Inca Gold

33 Conquistadors In addition to horses and steel, the conquistadors –Had superior ocean going ships –Had superior political organization of the European states – Carried infectious diseases that wiped out 95% of Native Americans (smallpox, measles, influenza, typhus, bubonic plague) –Had superior knowledge of human behavior from thousands of years of written history.

34 Conquistadors Pizarro got his treacherous ideas from the experience of Cortez. – The Incas knew nothing of Spaniards. Cortez and Montezuma

35 Why not the other way? Still, why was it that the Europeans had all of the advantages instead of the Incas? Why didn't the Incas invent guns and steel swords, have horses, or bear deadly diseases? Inca Inca Warrior

36 Food Production Why did food production not evolve in large, geographically suitable areas of the globe? Why did the dates of food production development vary so widely? Were the humans different, or was the environment?

37 All people on earth were once hunter- gathers; why did some leave this behind and others not?

38 Food production systems evolved as a result of the accumulation of many separate decisions about allocating time and effort (Diamond). Food production developed as a way to provide the most calories (particularly of protein) with the least amount of effort.

39 The major significance of evolving into food production was to free up time so that certain tribal members could become SPECIALISTS: weapon makers, container makers, tribal leaders, medicine men, etc.

40 In cultures that evolved food production, the major factors contributing were: Decline in the availability of wild foods Increased availability of domesticable wild plants Development of technologies for collecting, processing and storing wild foods

41 How Were Wild Plants Domesticated?

42 Selection of largest and most attractive plants Preferential planting of best seeds Favoring beneficial mutations in plants (almonds) Selection of seeds that did not germinate simultaneously Selection of self-pollinators

43 Problems With Food Cultivation in Much of North America Major grain crop, corn, was very tiny, took thousands of years to evolve into modern size, not self-pollinating, and very low in protein Wild grasses largely limited to rice which also was low in protein Few (turkey and dog) domesticable animals to assist in production or to be eaten

44 Advantages of Western Eurasia Largest land mass in Mediterranean climate Great diversity of wild plants and animals Greatest seasonal climatic varietymore annuals 56 prize grasses

45 Range of altitudes led to staggered harvests Less competition from hunter-gatherers

46 Why New Guineans Didnt Develop Agriculture No domesticable grain crops Root crops lacking in protein No domesticable large mammal species

47 In coastal areas, consumed fish which shows openness to new foods In highlands, frequent protein starvation (which may have been a factor in areas where cannibalism existed)

48 Mississippi Florescence Refers to arrival of dozens of crops from Mexico. Once introduced, they were widely cultivated. This is evidence that once crops arrived, indigenous people planted and cultivated them.

49 All of this supports Diamonds thesis that differences in the arrival of plant production were based, not on limitations of the people but on biota.


51 The Role of Domesticable Animals in Food Production Domesticable animals are all alike; every undomesticable animal is undomesticable in its own way (Diamond).

52 Provided by Domestic Animals Meat Milk Products Fertilizer Transport Leather Military assault vehicles Plow traction (Germs)

53 Domestication is the process by which wild animals are transformed into something more helpful to humans.

54 Eurasia had 13 0f 14 domesticable animals.

55 The Major Five Sheep (Asiatic mouflon) Goat (Besoar goat of West Asia) Cow, ox, cattle (aurochs, now extinct, found in Eurasia Pig (wild boar, distributed over Eurasia and North Africa) Horse (wild horses from Russia)

56 The Minor Nine Camel (Arabia and Central Asia) Llama and alpaca (Andes) Donkey (African wild ass of Northern Africa) Reindeer (Northern Eurasia) Water buffalo (Southeast Asia)

57 Yak (Himalayas and Tibetan plateau) Bali cattle (banteng from Southeast Asia) Mithan (the gar of India and Burma)

59 Why Were Eurasias Animals Domesticated? Why Eurasia's horses but not Africas zebras? Why Eurasias pigs but not America's or Africas? Why Eurasias cattle but not buffalo?

60 Was it the peoples or the animals? The evidence that it was the animals themselves is based on the rapid adoption of domesticable animals once they arrived from other places.

61 There were repeated 19 th and 20 th century attempts to domesticate Eland, moose, ox, zebra, and bison. Modern geneticists met with little success so too indigenous peoples.

62 Why perpetually wild? Diet Growth rate Problems with Captive Breeding (pandas, cheetahs, vicunas Nasty and dangerous dispositions ( grizzly bear, American buffalo, zebra) Tendency to panic when approached (all gazelle species)

63 Social structure: Domestic animals live in herds, have a dominance hierarchy, overlap ranges rather than have exclusive territory.

64 Role of Direction of Major Axes in Dissemination of Ideas and Products

65 Why Did Ideas About Plants and Animals spread more quickly in Eurasia? Axes Eurasia Africa The Americas

66 GERMS! Diseases have been major shapers of history Influenza of 1918 European conquests of Americas (Spanish conquistadors, English settlers)

67 Eurasia sight of major infectious diseases: Why? Many diseases zoonotic Critical masses of people because of efficient food production Crowd diseases could not survive in small bands of people Leprosy, yaws, hookworms may be oldest because could survive in smaller tribes

68 Farming and agriculture increase diseases and disease spread Farms live around and often fertilize with their own sewage Densely packed human populations Evolution of world trade routes (distributed smallpox)

69 New Zoonotic Diseases? AIDS Lassa Fever Lyme Disease Hanta viruses

70 Syphilis is suspected of being only disease transferred from native Americans to Euarsia.

71 Development of Written Language Critical Writing is the key to transmit knowledge to distant lands and to retain knowledge Writing was developed by agricultural groups because food production allows for the development of specialists (scribes)

72 With the exception of Egyptian and Chinese all writing systems are derived from early Mesoamerican writing. Phoenicians provided representational consonantal alphabet Greeks invented representation of vowel sounds

73 Written language aided in conquering of new lands.


75 Why Did Eurasians Possess Technology First? Technology develops cumulatively rather than in isolated acts Technology finds most of its uses AFTER invention Technology requires a society to adopt it

76 Religions vary widely in their willingness to adopt technology Depending on geography, information about technological advances will reach some people and not others

77 Descendents of those societies that achieved centralized government and organized religion earliest ended up dominating the modern world.

78 The combination of government and religion has thus functioned together with germs, writing, and technology as one of the four main sets or proximate agents leading to history's broadest pattern. How did governments and religions arise?

79 Levels of Social Organization Evolve from Least to Most Complex Bands Tribes Chiefdoms States

80 Bands Tiny populations: typically 5-80 people Most are close relatives by birth or marriage All humans lived in bands until 40,000 years ago

81 Bands Usually nomadic: live in areas where food is scarce Land used jointly by whole group No specialization: all able-bodied individuals forage for food Economic System: Reciprocal Exchange No laws, treaties, or police to help resolve disputes

82 Tribes Society with hundreds of people, usually settled in many villages Shared language and culture More than one kinship group Land belongs to clans within a tribe Everyone knows everyone else by name and relationship

83 Tribes Social system egalitarian No upper or lower class No one can become more wealthy Government still egalitarian Decisions are made in a group May have big man with limited power; still would live like others

84 Chiefdoms Population: several thousands to tens of thousands Arose about 7500 years ago with rising populations In 1492 widespread in North and South America, Africa, Polynesia

85 States Populations of 50,000 to 1 billion Usually have literate elites Sometimes literate population Arose first in Mesopotamia, later in Mesoamerica, China, Southeast Asia, Andes, West Africa

86 Religion Early: tribal deities Polytheist Standardized temples and religions evolve under influence of kings Often these kings were head of state religion Monotheism evolves Temples or religious centers are crucial to economic redistribution, writing, crafts, technology

87 Advantages of States and Centralized Religions Primarily as they allow for specialization Provide critical mass for technologies to emerge, be adapted, and spread May reduce numbers of armed conflicts Dissemination of ideas and information

88 Religions Can unite a people with shared goals and beliefs May create central mythos: idea that God wants them to spread this religion Missionaries played critical role in providing Eurasian ideas and technology to isolated populations.

89 Development Diagram Ultimate Factors Proximate Factors East/West Axis Ease of species spreading Many suitable wild species Many domesticated plant and animal species Food surpluses, food storage Large, dense, sedentary, stratified societies technology Epidemic disease Political organization, writing Ocean-going ships Guns, steel swords horses

90 Chapter 16: How China Became Chinese




94 Isolation + Conquest = Writing System and Language Unification






100 The End of Chinas Reign In the 1400s, fleets of a hundred treasure ships120 meters long sent to Africa In 1433, a political argument in the Chinese court led to the suspension of naval activities Due to political unification, this effectively halted Chinas global progress.

101 The irony is that Chinas greatest strength, political unity, is what led to Chinas global downfall.

102 My years in New Guinea have convinced me that people around the world are fundamentally similar. Wherever you go, you can find people who are smart, resourceful, and dynamic. No society has a monopoly on those traits. Of course, there are huge cultural differences, but they're mainly the result of inequality; they're not its root cause. Ultimately what's far more important is the hand they are dealt, the raw materials they had at their disposal. Jared Diamond
