Individuals sharing recent ancestors are likely to co-inherit large identical-by-descent (IBD) genomic regions. The distribution of these IBD segments in a population may be used reconstruct past demographic events such as effective size variation, but accurate detection is difficult ancient DNA data and underrepresented populations with limited reference data. In this work, we introduce an method for inferring variation during the ~2000 years both modern data, called HapNe. HapNe infers...
The Yamnaya archaeological complex appeared around 3300BCE across the steppes north of Black and Caspian Seas, by 3000BCE reached its maximal extent from Hungary in west to Kazakhstan east. To localize ancestral geographical origins among diverse Eneolithic people that preceded them, we studied ancient DNA data 428 individuals which 299 are reported for first time, demonstrating three previously unknown genetic clines. First, a “Caucasus-Lower Volga” (CLV) Cline suffused with Caucasus...
Abstract The Linearbandkeramik (LBK) Neolithic communities were the first to spread farming across large parts of central Europe, settling fertile regions from Ukraine France during second half 6th millennium BCE. LBK had a high degree material culture uniformity, albeit with regional differences in settlement patterns, subsistence, and mortuary practices. To date, ancient DNA data individuals have been generated for limited number locations often small sample sizes, making it challenging...
1 Abstract Individuals sharing recent ancestors are likely to co-inherit large identical-by-descent (IBD) genomic regions. The distribution of these IBD segments in a population may be used reconstruct past demographic events such as effective size variation, but accurate detection is difficult ancient DNA (aDNA) data and underrepresented populations with limited reference data. In this work, we introduce an method for inferring variation during the ~2,000 years both modern aDNA data, called...
