Study Notes
Biological Exchange
- Biological exchange, the transfer of plants, animals, and pathogens, has been a significant factor in human history.
- Early examples include the intentional introduction of animals by settlers and unintentional spread of diseases.
The Pace of Biological Exchange
- The pace of biological exchange accelerated during periods of increased trade and travel.
- The Silk Roads during the Roman and Han Empires facilitated the exchange of species between China and the Mediterranean region.
- Trade in the Arabian Sea in the ninth century CE spurred the exchange of crops between India, East Africa, and the Mediterranean.
Americas Biologically Apart
- The Americas remained largely isolated from the Old World web of exchange before 1492.
- The only significant exchanges were the introduction of the dog from Siberia and the export of the sweet potato to Polynesia.
- Australia and New Zealand also remained isolated, hosting unique flora and fauna.
After the Voyages of Columbus
- The voyages of Columbus linked the Americas to the Old World web, creating a biologically interactive network.
- This exchange, known as the Columbian Exchange, transformed both the Americas and the Old World.
Columbus's Contribution
- Columbus's expeditions initiated the Columbian Exchange, with the deliberate transfer of species between Europe and the Americas.
- New World inhabitants received hundreds of plants and animals from Eurasia and Africa, as well as devastating diseases.
The Impact of Deadly Diseases, 1492-1700
- European travelers introduced numerous diseases to the Americas, including smallpox, measles, mumps, whooping cough, and influenza.
- These diseases were endemic in the Old World, but native Americans had no prior exposure and lacked immunity.
- European colonization further weakened native populations, making them more susceptible to disease.
- Yellow fever and falciparum malaria, spread by mosquitos, also arrived from Africa, contributing to the devastating impact.
The Impact of the Deadly Diseases on a Mexican Village
- A Mexican village in the 16th century experienced a catastrophic epidemic.
- The villagers were helpless and unable to care for themselves, leading to death from both the disease and starvation.
Consequences of the Epidemics
- In many communities, the social fabric collapsed due to the intensity of the epidemics and the resulting loss of hope.
- Population decline in the Americas was dramatic, dropping 70-95% between 1492 and 1650.
The Americas' Infectious Disease's Lesser Impact on Africa and Eurasia
- The Americas had limited infectious diseases that significantly impacted Africa and Eurasia.
- The first migrants to the Americas had spent time in cold climates that may have killed off some pathogens.
- The lack of domesticated herd animals in the Americas reduced the likelihood of zoonotic diseases.
- The Columbian Exchange was largely unidirectional, with the Americas suffering the most significant consequences.
The Columbian Exchange and Domesticated Animals
- The Columbian Exchange was also asymmetrical with respect to domesticated animals.
- While turkeys and guinea pigs were introduced to other continents, they did not become widespread.
- Alpacas and llamas never prospered outside their native Andes.
The Beginnings of a Global Web
- The oceanic voyages of the 15th and 16th centuries connected continents into a single global web.
- The Americas, previously largely isolated, now became integrated into this global web.
The Oceanic Voyaging Tightened Linkages
- Oceanic voyaging strengthened connections within the Old World web, facilitating trade and cultural exchange.
The Spinning of the Global Web
- The formation of the global web had significant consequences, including biological globalization and the rise of European influence.
- The spread of Atlantic Europeans, with their advanced navigation and military capabilities, significantly shaped world history.
The Penalties of Isolation
- Societies isolated from the Old World web suffered from lack of immunity to diseases like measles, influenza, and smallpox.
- Isolated people also lacked advanced technology and weaponry, making them vulnerable to conquest.
The Transformation of Global Web
- The global web resulted in a decrease in cultural diversity, with the spread of major religions like Christianity and Islam.
- The increased use of languages like Arabic, Spanish, and English also led to a reduction in linguistic diversity.
Conclusion
- The world in 1400 consisted of multiple interconnected webs, with the Americas largely isolated.
- The voyages of Columbus and other explorers connected the world into a single global web, with profound consequences for biological exchanges, cultural dynamics, and global power.
