In 2016, Ludovic Orlando, a genetics researcher, embarked on the Pegasus Project, an ambitious endeavor to use genetics to discover the origin of the modern horse. There were plenty of theories as to who domesticated horses first–but Ludovic’s team came up with their answer: They emerged on the western Eurasian steppe around 4200 years ago. But that revelation was only the beginning of Ludovic’s work, as he dug into the genetic origins of different kinds of horses, like the Arabian horse, as well as charted how the horse’s genetic diversity changed over time. His research is collected in his new book Horses: A 4,000-Year Genetic Journey Across the World (Princeton UP, 2025) Ludovic Orlando is a CNRS Silver Medal–winning research director and founding director of the Centre for Anthropobiology and Genomics of Toulouse at the University of Toulouse in France. His work has appeared in leading publications such as Nature, Science, and Cell. He is a recipient of the American Association for the Advancement of Science’s Newcomb Cleveland Prize.
