Ludovic Orlando

Join asteroid specialist Sarah Russell, who studies interstellar dust, paleo geneticist Ludovic Orlando, who researches horse domestication, and epidemiologist Katerina Laporta, who examines historical rumor spread. They discuss the fascinating parallels between the spread of fear during the French Revolution and modern-day events, revealing how citizen militias shaped revolutionary ideas. Furthermore, uncover the genetic evolution of horses and the cosmic origins of asteroids like Bennu, highlighting the connection between our ancient past and current scientific endeavors.

Étienne Patin, biologiste des histoires génétiques; Michel Signoli, archéologue des sépultures catastrophiques; Ludovic Orlando, paléogénéticien spécialiste d'ADN ancien; Maxime Schwarz, chercheur pasteurien et historien. Ils évoquent la découverte du bacille par Yersin, la validation génétique de la peste noire, les méthodes d’extraction et de séquençage de l’ADN ancien, et l’impact des épidémies sur le génome humain.

Ludovic Orlando, a leading genetics researcher and director at the Centre for Anthropobiology and Genomics of Toulouse, dives into the fascinating world of horse domestication. He reveals the origins of modern horses around 4,200 years ago in the Eurasian steppe and discusses the Botai culture's early but unsuccessful domestication attempts. With insights on the spread of domestic horses and the emergence of the Arabian breed, he also addresses the surprising decline in horse genetic diversity and the future of equine genetics through cloning and gene editing.
