Everything Everywhere Daily – "The Domestication of Sheep"

Host: Gary Arndt
Date: September 20, 2025

Episode Overview

In this episode, Gary Arndt explores the deep historical and cultural significance of sheep domestication. He traces the journey from the wild mouflon roaming ancient terrain to sheep’s role in developing economies, crafting societies, and creating iconic textiles. The episode examines how domesticating sheep fundamentally altered human existence—impacting food, clothing, trade, technology, and even writing.

Key Discussion Points & Insights

1. Origins of Domestication

• Timeline & Location:
  • Sheep were domesticated approximately 9,000–11,000 years ago in the Fertile Crescent, which includes modern-day Iraq, Syria, southeastern Turkey, and western Iran.
  • "Sometime about 11,000 years ago, there was a revolution that forever changed humanity." [04:09]
• Ancestor:
  • The wild mouflon (Ovis orientalis) is the primary ancestor of modern sheep.

2. Process of Domestication

• Gradual Evolution:
  • Domestication was not a planned event but arose from incremental changes in human–animal relationships:
    • Following herds, offering protection, and eventually selective breeding over generations.
  • "Early humans likely didn't set out with any grand plan to domesticate sheep. Instead, the process probably began with opportunistic hunting and gradual behavioral changes by both sheep and humans." [06:14]
• Co-Evolution:
  • Both humans and sheep influenced each other’s development in what scientists term "co-evolution."

3. Biological & Physical Changes in Sheep

• Physical Adaptations:
  • Domesticated sheep became smaller (neoteny), with shorter faces, smaller brains, and diminished horns.
  • “Their skulls became smaller, their faces shortened, and their brain size decreased.” [08:36]
• Wool Revolution:
  • Early sheep were initially bred for meat, hides, and bones.
  • Through selective breeding, thick, soft fleeces developed—ushering in the wool revolution.

4. Impact of Wool on Human Society

• Textile Innovations:
  • Wool’s crimped fibers offered warmth, breathability, moisture absorption, and ease of dyeing.
  • "Wool was in many ways superior to other materials for clothing, because its crimped fibers trapped air, providing excellent insulation against the cold while still remaining breathable." [10:10]
• Renewability:
  • Unlike hides (which required killing the animal), wool was a sustainable, annual resource.

5. Spread of Sheep and Pastoralism

• Expansion:
  • Sheep reached Europe by 7,000 years ago and Asia/North Africa by 5,000 years ago.
  • “This spread wasn't just about the animals themselves. It represented the movement of entire pastoral communities.” [13:26]
• Cultural Bridges:
  • Pastoral nomads facilitated trade, culture, and technology transfer between regions.

6. Sheep in Ancient Societies

• Economic, Religious, and Social Roles:
  • Sheep often symbolized wealth, were used as currency, and became ritual items.
• Technological Innovations:
  • Wool processing (spinning, weaving) drove new crafts and tools.
• Sheepskin:
  • Used for clothing, gloves, bookbindings, and especially as parchment for writing.

7. Writing & Symbolism

• Parchment:
  • Sheepskin provided a plentiful and cheap medium for manuscripts in Europe.
  • “Thin sheepskin parchment was abundant and cheaper than calf vellum, making it the most common writing surface for manuscripts in Europe.” [19:25]
• Symbolic Value:
  • The Golden Fleece in Greek mythology represented wealth and authority.
  • Actual ancient technique: rivers with gold flecks used sheepskins to capture gold ([21:18]).

8. Sheep in Modern History

• Medieval Europe:
  • Sheep became linchpins of economies (notably in England, Spain, and the Low Countries).
  • The Spanish developed prized Merino wool, tightly controlled until the 18th century.
• Global Spread:
  • With colonization, sheep reached the Americas, Australia, and New Zealand, where wool and meat industries exploded.

9. North America’s "Sheep Paradox"

• Sheep vs. Cattle:
  • Despite ideal land for sheep, cattle prevailed in the U.S. due to market and cultural preferences.
  • “The growing American population in the 19th century demanded beef more than mutton or lamb.” [27:20]
• Range Wars:
  • Intense conflict arose between cattle ranchers and sheepherders in the West, sometimes turning violent.

10. Contemporary Sheep Industry

• Global Distribution:
  • 1.2 billion sheep live worldwide, with the largest populations in China, Australia, India, Sudan, and Iran.
• Wool’s Changing Role:
  • Wool is now a niche fiber (less than 2% of global fiber production), but remains prized for its unique qualities.
  • “It's warm, breathable, naturally fire resistant, odor resistant, and biodegradable.” [32:18]
• Dairy Products:
  • Sheep’s milk cheeses (Roquefort, Manchego, Pecorino Romano, Feta) are now economically significant.

11. Sheep Breeding Today

• Diversity:
  • Over 1,000 recognized breeds exist, making sheep one of the most diverse domesticated animals globally.

Notable Quotes & Memorable Moments

• On Co-Evolution:
  • "This created what scientists call co-evolution, with both species gradually changing in response to their relationship with each other." [07:28]
• On Wool’s Transformative Power:
  • “This transformation was revolutionary because it gave humans access to a renewable source of warm, workable wool.” [09:41]
• On Sheepskin and Writing:
  • “Its fibrous structure made it more resistant to erasure and alteration than paper.” [20:30]
• The Golden Fleece Reality:
  • “Some rivers in the Caucasus had flecks of gold that would travel downstream. By placing a sheepskin with wool in the river, the fibers in the wool would catch flecks of gold.” [21:18]
• On the Great American Sheep-Cattle Divide:
  • “Cattlemen argued that sheep cropped grass too close to the ground, leaving pastures barren, while cattle grazing left grass that could regrow.” [29:22]

Conclusion

Gary finishes by connecting the legacy of ancient shepherds to the present day:

"All of the wool, mutton, lamb, and sheep cheese produced in the world today... are all the direct legacy of the original shepherds who cozied up to wild sheep somewhere in the fertile crescent almost 10,000 years ago." [35:23]
