Horses revolutionized human history with fast mobility. However, the timeline between their domestication and widespread integration as a means of transportation remains contentious. In new research, scientists from the Centre d’Anthropobiologie et de Génomique de Toulouse and elsewhere assembled a collection of 475 ancient horse genomes to assess the period when these animals were first reshaped by human agency in Eurasia. Librado et al. found...
