Adulis, located on the Red Sea coast in present-day Eritrea, was a bustling trading centre between the first and seventh centuries CE. Several classical geographers—Agatharchides of Cnidus, Pliny the Elder, Strabo—noted the value of Adulis to Greco-Roman Egypt, particularly as an emporium for living animals, including baboons (Papio spp.). Though fragmentary, these accounts predict the Adulite origins of mummified baboons in Ptolemaic catacombs, while inviting questions on the geoprovenance of older (Late Period) baboons recovered from Gabbanat el-Qurud (‘Valley of the Monkeys’), Egypt. Dated to ca. 800–540 BCE, these animals could extend the antiquity of Egyptian–Adulite trade by as much as five centuries. Previously, Dominy et al. (2020) used stable isotope analysis to show that two New Kingdom specimens of Papio hamadryas originate from the Horn of Africa. Here, we report the complete mitochondrial genomes from a mummified baboon from Gabbanat el-Qurud and 14 museum specimens with known provenance together with published georeferenced mitochondrial sequence data. Phylogenetic assignment connects the mummified baboon to modern populations of P. hamadryas in Eritrea, Ethiopia, and eastern Sudan. This result, assuming geographical stability of phylogenetic clades, corroborates Greco-Roman historiographies by pointing toward present-day Eritrea, and by extension Adulis, as a source of baboons for Late Period Egyptians. It also establishes geographic continuity with baboons from the fabled Land of Punt (Dominy et al., 2020), giving weight to speculation that Punt and Adulis were essentially the same trading centres separated by a thousand years of history.

myBaits targeted NGS kits can greatly increase the power and efficiency of forensics research on both mitochondrial and nuclear DNA.

myBaits Custom DNA-Seq capture kits provide rapid, selective enrichment of target regions of interest from NGS libraries built from DNA samples.

myBaits Custom Methyl-Seq kits provide deep sequencing of target regions from NGS libraries of bisulfite- or enzymatic-converted DNA samples.

American bison demonstrated differential patterns of extinction, survival, and expansion since the terminal Pleistocene. We determined population dynamics of the Northern Great Plains bison using 40 mitochondrial genomes from radiocarbon dated remains with the age ranging from 12,226 to 167 calibrated years before present. Population dynamics correlated with environmental and anthropogenic factors and was characterized by three primary periods: terminal Pleistocene population growth starting 14,000 years ago, mid Holocene demographic stability between 6700 and 2700 years ago, and late Holocene population decline in the last 2700 years. Most diversification of mtDNA haplotypes occurred in the early Holocene when bison colonized new territories opened by retreating ice sheets. Holocene mtDNA lineages were not found in modern bison and lacked association with archaeological sites and morphological forms.

The metabarcoding of vertebrate DNA found in invertebrate-derived DNA (iDNA) has proven a powerful tool for monitoring biodiversity. To date, iDNA has primarily been used to detect the presence/absence of particular taxa using metabarcoding, though recent efforts demonstrated the potential utility of these data for estimating relative animal abundance. Here, we test whether iDNA can also be used to reconstruct complete mammalian mitogenomes and therefore bring the field closer to population-level analyses. Specifically, we used mitogenomic hybridization capture coupled with high-throughput sequencing to analyze individual (N = 7) or pooled (N = 5) fly-derived DNA extracts, and individual (N = 7) or pooled (N = 1) leech-derived DNA extracts, which were known a priori to contain primate DNA. All sources of iDNA showed their ability to generate large amounts of mammalian mitogenomic information and deeper sequencing of libraries is predicted to allow for even more complete recovery of primate mitogenomes from most samples (90%). Sixty percent of these iDNA extracts allowed for the recovery of (near) complete mammalian mitochondrial genomes (hereafter mitogenomes) that proved useable for phylogenomic analyses. These findings contribute to paving the way for iDNA-based population mitogenomic studies of terrestrial mammals.

Extinct lineages of Yersinia pestis, the causative agent of the plague, have been identified in several individuals from Eurasia between 5000 and 2500 years before present (BP). One of these, termed the ‘LNBA lineage’ (Late Neolithic and Bronze Age), has been suggested to have spread into Europe with human groups expanding from the Eurasian steppe. Here, we show that the LNBA plague was spread to Europe’s northwestern periphery by sequencing three Yersinia pestis genomes from Britain, all dating to ~4000 cal BP. Two individuals were from an unusual mass burial context in Charterhouse Warren, Somerset, and one individual was from a single burial under a ring cairn monument in Levens, Cumbria. To our knowledge, this represents the earliest evidence of LNBA plague in Britain documented to date. All three British Yersinia pestis genomes belong to a sublineage previously observed in Bronze Age individuals from Central Europe that had lost the putative virulence factor yapC. This sublineage is later found in Eastern Asia ~3200 cal BP. While the severity of the disease is currently unclear, the wide geographic distribution within a few centuries suggests substantial transmissibility.
