We present a new and considerably improved version of RoAM (Reconstruction of Ancient Methylation), a flexible tool for reconstructing ancient methylomes and identifying differentially methylated regions (DMRs) between populations. Through a series of filtering and quality control steps, RoAM produces highly reliable DNA methylation maps, making it a valuable tool for paleoepigenomics studies. We apply RoAM to pre-and post-Neolithic transition Balkan samples, and uncover DMRs in genes related to sugar metabolism. Notably, we observe post-Neolithic hypermethylation of PTPRN2, a regulator of insulin secretion. These results are compatible with hypoinsulinism in pre-Neolithic hunter-gatherers.

Objectives: This study explores cranial morphological variation and population continuity in the Carpathian Basin from the 1st to 13th centuries CE. It focuses on assessing biological differences and similarities across major archaeological periods, with particular emphasis on the Avar, Hungarian Conquest, and Árpádian Age populations.
Materials And Methods: A total of 1,597 adult crania (864 males, 733 females) were analyzed using six neurocranial measurements.

Between the third and sixth centuries AD (Anno Domini), the Xianbei emerged as a dominant nomadic power in the Eastern Eurasian Steppe, distinguished by their exceptional equestrian culture and the pivotal role of cavalry in warfare. Despite their historical significance, detailed knowledge of their cavalry's weaponry and equipment-particularly armour-remains fragmentary. As a critical element of military technology, armour offers valuable insights into ancient combat strategies and cultural practices.

The Ancestral Recombination Graph (ARG), which describes the genealogical history of a sample of genomes, is a vital tool in population genomics and biomedical research. Recent advancements have substantially increased ARG reconstruction scalability, but they rely on approximations that can reduce accuracy, especially under model misspecification. Moreover, they reconstruct only a single ARG topology and cannot quantify the considerable uncertainty associated with ARG inferences.

The advent of high-throughput genomic sequencing has provided unprecedented access to genome-scale data. This deluge of data has yielded new insights into phylogenetic relationships across the tree of life. However, incongruent results arising from different data partitions or from the use of different analyses have often been overlooked or insufficiently explored.
