New DNA Study Redefines Timeline of Horse Domestication
Research reveals dual domestication events and rapid spread of modern horse lineage around 4,200 years ago.
- Scientists analyzed 475 ancient and 77 modern horse genomes to trace domestication history.
- First domestication by the Botai culture 5,500 years ago focused on milk and meat, not transportation.
- Modern horse lineage emerged in the Pontic-Caspian Steppe, rapidly spreading across Eurasia by 2,200 BCE.
- Breeding practices changed to halve generation times, boosting horse production.
- Findings challenge previous theories about horse domestication and early human migrations.
