We have examined a 5th to 6th century inhumation from Great Chesterford, Essex, UK. The incomplete remains are those of a young male, aged around 21-35 years at death. The remains show osteological evidence of lepromatous leprosy (LL) and this was confirmed by lipid biomarker analysis and ancient DNA (aDNA) analysis, which provided evidence for both multi-copy and single copy loci from the Myco...
Abstract Western Iberia Early Neolithic has been described as an ultimate and very altered form of the Mediterranean Neolithisation process. Despite its Atlantic position, this territory – corresponding mainly to Central/Southern Portugal is, in physical cultural geography, a landscape deeply connected historical process arriving from beyond Strait Gibraltar. The presence cardial pottery led ar...
Analysis of ancient DNA (aDNA) extracted from Ascaris is very important for understanding the phylogenetic lineage of the parasite species. When aDNAs obtained from a Joseon tomb (SN2-19-1) coprolite in which Ascaris eggs were identified were amplified with primers for cytochrome b (cyt b) and 18S small subunit ribosomal RNA (18S rRNA) gene, the outcome exhibited Ascaris specific amplicon bands...
Rye (Secale cereale ssp. L.) is a secondary domesticate, considered to have originated as weed in wheat fields and developed traits of domestication by evolving similar physiological morphological characteristics those wheat. Although it migrated into Europe possessing traits, became one the most significant crops grown large parts from medieval period onward. Within modern borders Germany, rye...
Ancient DNA (aDNA) research involves invasive and destructive sampling procedures that are often incompatible with anthropological, anatomical, and bioarcheological analyses requiring intact skeletal remains. The osseous labyrinth inside the petrous bone has been shown to yield higher amounts of endogenous DNA than any other skeletal element; however, accessing this labyrinth in cases of a comp...
Owing to exceptional biomolecule preservation, fossil avian eggshell has been used extensively in geochronology and palaeodietary studies. Here, we show, to our knowledge, for the first time that fossil eggshell is a previously unrecognized source of ancient DNA (aDNA). We describe the successful isolation and amplification of DNA from fossil eggshell up to 19 ka old. aDNA was successfully char...
The rate of change in DNA is an important parameter for understanding molecular evolution and hence for inferences drawn from studies of phylogeography and phylogenetics. Most rate calibrations for mitochondrial coding regions in marine species have been made from divergence dating for fossils and vicariant events older than 1-2 My and are typically 0.5-2% per lineage per million years. Recentl...
DNA de novo assembly can be used to reconstruct longer stretches of (contigs), including genes and even genomes, from short sequencing reads. Applying this technique metagenomic data derived archaeological remains, such as paleofeces dental calculus, we investigate past microbiome functional diversity that may absent or underrepresented in the modern gene catalogue. However, compared samples, a...
