Summary Horse domestication revolutionized warfare and accelerated travel, trade, and the geographic expansion of languages. Here, we present the largest DNA time series for a non-human organism to date, including genome-scale data from 149 ancient animals and 129 ancient genomes (≥1-fold coverage), 87 of which are new. This extensive dataset allows us to assess the modern legacy of past equestrian civilizations. We find that two extinct horse lineages existed during early domestication, one at the far western (Iberia) and the other at the far eastern range (Siberia) of Eurasia. None of these contributed significantly to modern diversity. We show that the influence of Persian-related horse lineages increased following the Islamic conquests in Europe and Asia. Multiple alleles associated with elite-racing, including at the MSTN “speed gene,” only rose in popularity within the last millennium. Finally, the development of modern breeding impacted genetic diversity more dramatically than the previous millennia of human management.

The horse is central to many Indigenous cultures across the American Southwest and the Great Plains. However, when and how horses were first integrated into Indigenous lifeways remain contentious, with extant models derived largely from colonial records. We conducted an interdisciplinary study of an assemblage of historic archaeological horse remains, integrating genomic, isotopic, radiocarbon, and paleopathological evidence. Archaeological and modern North American horses show strong Iberian genetic affinities, with later influx from British sources, but no Viking proximity. Horses rapidly spread from the south into the northern Rockies and central plains by the first half of the 17th century CE, likely through Indigenous exchange networks. They were deeply integrated into Indigenous societies before the arrival of 18th-century European observers, as reflected in herd management, ceremonial practices, and culture.

Anatomical variations of the thoracic duct course are common in humans and domestic animals. They are important in thoracic surgery and in application of surgical techniques in experimental animals. The pig is a frequently used animal model due to numerous similarities between human and porcine anatomy and physiology. We revealed the position of the cisterna chyli, and the origin, course and termination of the thoracic duct by fine dissection on fifteen Yorkshire pig carcasses. The pigs were 2.5 months old with a body mass range from 10 to 15 kg. In this study we present our macroscopic observations. The cisterna chyli and thoracic duct had a common position, form and course in ten (67%) specimens. Anatomical variations of the precardiac course of the thoracic duct were observed in five animals (33%). Knowledge of these anatomical features should enhance the use of swine as an experimental model.

Two single bovine burials and one mixed animal burial (containing bovine and canid skeletal remains) have been unearthed at two Baden culture sites, Aljmaš‐Podunavlje and Osijek‐Retfala located in Eastern Croatia. Zooarchaeological analysis attributed the faunal remains to domesticated cattle (Bos taurus) and in one case a dog (Canis familiaris). Almost complete and articulated skeletons of subadult or adult cows were found in all three examined features, while pit 59/60 from Aljmaš also contained a skull belonging to an adult‐domesticated cattle and a skeleton of a very young dog, 2–3 months old. All of the skeletons are well preserved and display no evidence of carcass processing indicating that the animals were buried intentionally. Consideration of the positions in which these animals were interred and their relationship with nearby deposits enables discussion of potential animal burial strategies and possible connections with certain ritual practices in which cows and in one case a dog played important roles. The described burials represent the southernmost known distribution of the rite discussed. Copyright © 2015 John Wiley & Sons, Ltd.
