Body Size, Dental Pathology, and Maternal Genetic Diversity of Ancient Horses in the Eastern Baltic Sea Region and Western Russia

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT The early evolutionary history of modern domestic horses (Equus caballus/Equus ferus caballus), known as the DOM2 lineage, is well documented due to numerous archaeological and ancient DNA (aDNA) studies. Although many uncertainties remain in the domestication timeline, current evidence suggests that the domestication of modern horses began in
