Summary
Massively parallel sequencing (MPS) successfully analyzed ancient skeletal remains, providing detailed biometric and ancestry information. This method offers a powerful tool for identifying unknown individuals when traditional reference samples are unavailable.
Area of Science:
- Forensic Genetics
- Archaeogenetics
- Human Identification
Background:
- Forensic DNA analysis of unidentified remains typically requires reference samples, which are often unavailable for historical or archaeological cases.
- Massively parallel sequencing (MPS) presents a promising approach for generating biometric data from degraded samples, aiding identification.
- This study utilized historical skeletal remains to assess MPS feasibility for modern forensic casework.
Purpose of the Study:
- To genetically characterize 140-year-old human skeletal remains from Deadwood, South Dakota, using Massively Parallel Sequencing (MPS).
- To evaluate the effectiveness of MPS in obtaining comprehensive genetic information from ancient, degraded DNA.
- To demonstrate the utility of MPS for forensic identification in cases lacking traditional reference samples.
Main Methods:
- Massively parallel sequencing (MPS) was employed to analyze DNA extracted from 140-year-old human skeletal remains.
- A comprehensive panel of forensic genetic markers was utilized, including Y-STRs, Y SNPs, ancestry-informative SNPs, phenotype-informative SNPs, autosomal STRs, X-STRs, and mtDNA.
- Genetic profiles were analyzed to determine Y-chromosome and mtDNA haplogroups, ancestry, and phenotypic traits.
Main Results:
- High-quality genetic profiles were obtained, including Y-chromosome (25/26 Y-STRs, 34/34 Y SNPs) and mtDNA (10 regions).
- Analysis revealed European ancestry (haplogroups R1b and H1) and phenotypic traits consistent with light red hair and brown eyes.
- The results aligned with anthropological assessments, confirming male European ancestry.
Conclusions:
- This study is among the first to apply MPS with forensic genetic marker kits to historical human remains.
- MPS significantly enhances the amount of genetic information obtainable from limited and degraded DNA samples compared to conventional methods.
- The findings underscore the potential of MPS for characterizing modern forensic casework samples and identifying unknown individuals.

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

7.2K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.
