The Advent of Horse-Based Transportation

Context

• In a groundbreaking study published in the journal Nature, researchers have unveiled the long-debated mysteries surrounding the domestication of horses and its profound implications for human history.
• The study, based on genomic analysis of ancient and modern horse populations, sheds light on how these magnificent creatures were domesticated not once, but twice, reshaping the trajectory of civilizations across Eurasia.

Equine Domestication: A Contentious Timeline

• The timing of horse domestication and widespread use has been debated. Recent genome analysis of 475 ancient horses and 77 modern ones reveals that domestication occurred twice:

1. First Domestication: Initially in Central Asia (northern Kazakhstan) around 5,500 years ago by the Botai culture. This effort, focused on meat and milk, did not lead to widespread use.
2. Second Domestication: Began roughly 4,700 years ago in the western Russian steppes. This event led to horse-based mobility across Eurasia around 4,200 years ago, forming the foundation of all modern domestic horses.

Impact on Human History

• Transformative Animal: "Animal domestication changed human history, but no other animal was a king-maker as the horse was," stated evolutionary biologist Pablo Librado.
• Cultural Shaping: From Genghis Khan's empire to agricultural and urban transportation, horses have been crucial.
• Modern Implications: The study, published in Nature, underscores the horse's role in shaping modern societies.

Study Findings

• First Domestication: Central Asia's Botai culture domesticated horses for meat and milk, not for movement. Feral Przewalski’s horses in Mongolia descended from these.
• Second Domestication: Began in the western Russian steppes around 4,700 years ago, with widespread horse-based mobility emerging around 4,200 years ago.
• Genomic Evidence: A shift in breeding practices to meet horse demand, reducing generation time from eight to four years, indicated intensive breeding for traits like docility.

Breeding Practices

• Close-Kin Mating: Detected from around 4,200 years ago, likely enforced by breeders to select valued traits.
• Generation Time: Initially halved, later returned to normal until the industrial era, reflecting changes in breeding intensity.

Horse-Based Mobility and Warfare

• Cultural Interactions: Enabled rapid movement, speeding up communication and trade across Europe and Asia.
• Military Impact: Chariots and cavalry redefined warfare, contributing to the rise and fall of empires.
• Invention of Chariots: Spoke-wheeled chariots, lighter than wagons, could be pulled by horses, transforming transportation and warfare.

Reassessment of Human Migrations

• Indo-European Spread: Previously, horse-based mobility was thought to drive massive migrations around 3,000 BC.
• Revised View: New evidence suggests that during human steppe migrations 5,000 years ago, horses did not move across the steppe, altering our understanding of these migrations.

Conclusion

• The rise of horse-based transportation was a significant development, reshaping human mobility, communication, trade, and warfare, and leaving an indelible mark on the course of history.
