Widespread horse-based mobility arose around 2200 BCE in Eurasia.

ABSTRACT: Horses revolutionized human history with fast mobility¹. However, the timeline between their domestication and their widespread integration as a means of transport remains contentious^2-4. Here we assemble a collection of 475 ancient horse genomes to assess the period when these animals were first reshaped by human agency in Eurasia. We find that reproductive control of the modern domestic lineage emerged around 2200 BCE, through close-kin mating and shortened generation times. Reproductive control emerged following a severe domestication bottleneck starting no earlier than approximately 2700 BCE, and coincided with a sudden expansion across Eurasia that ultimately resulted in the replacement of nearly every local horse lineage. This expansion marked the rise of widesp
