Jared Diamond, a biologist from UCLA, has spent over 30 years researching the roots of global inequality. He aims to understand why some societies, particularly those of European origin, have become dominant, attributing their success to 'Guns, Germs, and Steel'. His quest began in Papua New Guinea, where he was challenged by a local man named Yali, who asked why white men had so much "cargo" while New Guineans had so little.
Diamond dismisses racial superiority as an explanation for inequality, highlighting the intelligence and resourcefulness of New Guineans. He notes their impressive survival skills in challenging environments, contrasting them with his own helplessness. Yali's question prompted Diamond to investigate the historical divergence of societies, questioning why New Guineans, with their ingenuity, did not develop advanced technologies or large cities like other civilizations.
To understand the origins of inequality, Diamond sought a time before significant disparities, turning back 13,000 years to the Middle East. During this period, hunter-gatherers lived mobile lives. A catastrophic climate change, a thousand-year drought, forced people to adapt. Around 11,200 years ago, at sites like Dhra in the Jordan Valley, people began settling in permanent villages and cultivating wild cereals like wheat and barley, marking the birth of farming and the world's first granaries.
The transition to farming led to the domestication of crops, as early farmers inadvertently selected for the most productive traits in plants. This accidental genetic engineering allowed for food surpluses, which hunter-gatherers could not achieve. The type of farming proved crucial, with regions having access to highly productive and storable crops gaining a significant advantage. New Guinea, despite having ancient farming practices, grew crops like taro and bananas, which were difficult to store and low in protein, hindering their societal development compared to those who farmed wheat and barley.
Around 9,000 years ago, the Middle East saw another revolution: animal domestication. Animals like goats, sheep, and later cows and horses, provided not only meat but also milk, wool, leather, and muscle power for plowing. These animals offered a dependable food supply and enhanced agricultural productivity, creating a symbiotic relationship with cereal farming. In contrast, New Guinea lacked suitable large mammals for domestication; their only large domestic animal was the pig, which couldn't provide the same diverse benefits or muscle power, leading to a reliance on human labor.
Diamond explains that out of 148 large plant-eating terrestrial mammals, only 14 have ever been successfully domesticated, all originating from Eurasia and North Africa, with the llama being the sole exception from South America. New Guinea, Australia, and sub-Saharan Africa had none of these key animals. The Middle East, known as the Fertile Crescent, was uniquely blessed with both the best crops and farm animals, giving its inhabitants a significant head start in developing complex societies.
The agricultural bounty in the Fertile Crescent allowed for the growth of larger villages and the emergence of specialists. Freed from farming, some individuals developed new skills and technologies, such as plaster making, a precursor to metalworking. This led to advanced civilizations like ancient Egypt. However, the Fertile Crescent's success was not without its challenges; its fragile environment was overexploited, leading to desertification. Despite this, its agricultural innovations spread along the east-west axis of Eurasia, fundamentally transforming societies from India to Europe by introducing high-yield crops and domesticated animals.
The agricultural package from the Fertile Crescent fueled European civilization and was eventually brought to the Americas by colonists, leading to their prosperity. Diamond argues that people worldwide are fundamentally similar in intelligence and resourcefulness. He contends that cultural differences are largely a result of inequality, not its cause. The key factor is the 'hand that people have been dealt' – the raw materials and geographical advantages available to them. Thus, the enduring disparities between societies, like the "cargo" Yali questioned, are ultimately rooted in geography, not inherent human differences.
