Difficulty: MediumThe Columbian Exchange

Source: Petition of the Nahua (indigenous) leaders of Xochimilco to the Spanish Viceroy, 1553.

"We are extremely poor and lack lands for our sustenance because the Spaniards have placed their cattle and sheep ranches on our fertile plains. The animals destroy our fields of maize, squash, and beans, which have fed our ancestors since ancient times. Furthermore, many of our people have died from the strange sicknesses that have spread through our towns, leaving us too weak to work the remaining land or repair our irrigation canals."

Based on the excerpt, which of the following was a direct ecological and economic consequence of the Columbian Exchange on indigenous populations in the Americas?

  1. The introduction of Old World domesticated animals disrupted native agricultural practices and ecosystems.Answer
  2. B
    The rapid adoption of New World crops such as wheat and rice allowed indigenous communities to quickly recover from population losses.
  3. C
    The Spanish colonial government resolved land disputes by granting indigenous communities ownership of the encomienda labor systems.
  4. D
    Indigenous societies across the Americas formed a unified, homogeneous alliance to collectively transition from farming to pastoralism.

Answer

The introduction of Old World domesticated animals disrupted native agricultural practices and ecosystems.
The correct answer is correct because cattle and sheep were Old World domesticated animals brought to the Americas as part of the Columbian Exchange. Their introduction and grazing habits severely disrupted traditional indigenous agriculture, which relied on unfenced crop fields of maize, squash, and beans.

Step-by-Step Solution

1
Analyze the historical source context and content.
The source is a 1553 petition from Nahua leaders detailing how Spanish livestock (cattle and sheep) destroyed traditional crops (maize, squash, beans) and how European diseases decimated their population, weakening their agricultural labor force.
Understanding the source is essential for identifying the specific historical consequences of the Columbian Exchange highlighted in the document.
2
Identify the biological and ecological components of the Columbian Exchange mentioned.
Cattle and sheep (Old World animals) were introduced to the Americas (New World), and smallpox/other pathogens led to demographic collapse.
Connecting the details in the text to the broader historical process of the Columbian Exchange allows for correct categorization of the exchange's direction and impacts.
3
Evaluate the choices to find the one that accurately matches both the source and historical facts.
The statement about Old World domesticated animals disrupting native agriculture is correct and directly supported by the text's mention of cattle and sheep destroying maize, squash, and bean fields.
Comparing options ensures that the selected answer is historically accurate and avoids common misconceptions about crop origins, labor systems, or indigenous cultural homogeneity.
