Article Synopsis
- - Horses transformed human mobility, but the timeline of their domestication and integration as transport is debated, with new genetic data being used to clarify this history.
- - Analysis of 475 ancient horse genomes indicates that modern domestic horses were shaped by human intervention around 2200 BCE, after a domestication bottleneck began around 2700 BCE, leading to a significant expansion across Eurasia.
- - Evidence also suggests that there was early horse husbandry in central Asia at Botai around 3500 BCE, prior to the establishment of contemporary horse bloodlines, challenging the notion of large herds being linked to migrations around 3000 BCE.
The analysis of stable isotopes in bone collagen allows us to infer the diet of the animals studied. This dataset consists of isotopic signatures (δC and δN) obtained by isotope ratio mass spectrometry from the skeletal remains of 42 equines (horse, ass and their hybrids) from the Can Roqueta site (Sabadell, Northeast Iberian Peninsula). Their chronology spans from Late Bronze Age to Late Roman Period, with particular emphasis on the Early Iron Age.

We document high genetic substructure between northwestern and southeastern hunter-gatherers before the spread of farming. We reveal sporadic contacts between Iberia and North Africa by ~2500 BCE and, by ~2000 BCE, the replacement of 40% of Iberia's ancestry and nearly 100% of its Y-chromosomes by people with Steppe ancestry.
