The mtDNA hgs: A, B, C, D, F, G, M, Y, and Z, are generally considered “eastern” Eurasian, and are currently found in high frequencies in the populations of East Asia, Central Asia and Siberia. The mtDNA hgs: H, HV, I, J, K, N, R, T, U, V, W, and X, are commonly considered to be “western” Eurasian, as they are currently found in highest frequency in the populations throughout Europe and southwest Asia (Derbeneva, 2009; Derenko et al., 2007; Gonzalez-Ruiz et al., 2012; Gubina et al., 2016; Keyser-Tracqui et al., 2006; Schurr & Pipes, 2011; Zhao et al., 2015). Twelve of the 20 samples sequenced in this study were eastern haplotypes (60%) and eight were western haplotypes (40%).

The SBA (n = 35) had 25 eastern haplotypes (71.43%) and 10 were western haplotypes (28.57%). The central slab burials (n = 25) had 16 eastern haplotypes (64%) and 9 were western haplotypes (36%). The Shunkhlai Uul population had seven eastern haplotypes (70%) and three were western haplotypes (30%).

Metagenomic analysis of Ancient Egyptian canopic jars

abstract :

Ancient Egyptian remains have been of interest for anthropological research for decades. Despite many investigations, the ritual vessels for the internal organs removed during body preparation—liver, lungs, stomach, and intestines, of Egyptian mummies are rarely used for palaeopathological or medical investigations. These artifacts, commonly referred to as canopic jars, are the perfect combination of cultural and biological material and present an untapped resource for both Egyptological and medical fields. Nevertheless, technical challenges associated with this archeological material have prevented the application of current ancient DNA techniques for both the characterization of human and pathogenic DNA. We present shotgun-sequenced metagenomic profiles and ancient DNA degradation patterns from multiple canopic jars sampled from several European museum collections and enumerate current limitations and possible solutions for the future analysis of similar material. This is the first-ever recorded evidence of ancient human DNA found in Ancient Egyptian canopic jars and the first associated metagenomic description of bacterial taxa in these funerary artifacts.
