Physical anthropology has been making progress in the field of forensic science. Forensic anthropology is the study of identifying and establishing identity of the skeletal remains present at the crime scene. The purpose of the chapter is to throw a light on the field of forensic anthropology as it seeks data like age, sex, ethnic groups, and other characteristic features after the examination of the skeletal remains. Forensic anthropology helps in determining the manner and cause of death, and if the body is still in the decompositions stage, time since death can also be estimated. Advancement in forensic anthropology will not only help to solve the case but it will also increase the opportunity to work in this area. In this chapter, there is an explanation of some of the methods used in forensic anthropology for the analysis of identification and other purposes.

Site Of Drowning

The application of diatom analysis in determining whether drowning was the cause of death has proved to be a valuable tool in forensic science. The basic principal of the “diatom test” in drowning is based on inference that diatoms are present in the medium where the possible drowning took place and that the inhalation of water causes penetration of diatoms into the alveolar system and blood stream, and thus, their deposition into the brain, kidneys, and other organs.I provide an informal assessment of “reliability” of the “diatom test” through correlations between control samples and samples from organs and clothing in two case studies. In studies, all organ and clothing samples except one had matching analogues in the modern diatom dataset from the body recovery sites, reinforcing drowning as the cause of death. The analogue matching provides further information on the precise site of drowning, in particular differentiating between drowning in a bathtub versus a naturally occurring body of water.

Single Nucleotide

Single Nucleotide polymorphisms are biological markers, helping researchers  to locate genes that are associated with various  diseases. When SNPs occur within a gene or in a regulatory region near a gene, they may play a more direct role in disease by affecting the gene's function. Most SNPs have no effect on health or development.Advancement in the field of genetics has resulted in the application of several techniques of molecular genetics in Pharmacogenomics. Nucleotide Polymorphisms (SNPs) holds the key in defining the risk of an individual’s susceptibility to various illnesses and response to drugs The body of human beings is composed of DNA which is a chemical molecule responsible for imparting phenotypic and genotypic characteristics to the individuals. The most recent advancement of molecular genetics, which has found application in forensic science, is the use of autosomal SNPs because they can provide information about the ancestral genetics of human beings.The primary aim of this research is to explore the significance of autosomal SNPs in forensic science through the identification of humans at a crime scene. A secondary qualitative research design has been selected for conducting this study. This secondary research is based on a systematic review of the studies which have provided an insight in the significance of autosomal SNPs in forensic sciences by using various Data search Engine. SNPs can be used in the forensic investigation for the identification of individuals present at the crime scene.

The biological samples used in forensics can contain DNA which is highly fragmented as a consequence of exposure to any of the numerous degrading factors. Analysis of the sequence or size of the products of Polymerase chain reaction is at present responsible for the analysis of remains of humans in forensics. Despite the effectiveness of protocols based on PCR, there are certain limitations that are presented by the low numbers of copies of the template and the variations that are imposed by the decaying process to the template. The primary aim of this research is to explore the significance of autosomal SNPs in forensic science through the identification of humans at a crime scene. This study provides an exploration of the applicability of autosomal SNPs for the identification of humans at crime scene. This would fill the gap present in the current literature regarding the significance of autosomal SNPs in the identification of humans during crime scene investigation. It will also enable the identification of the criminals involved in several types of the crimes ranging from general theft to rape and sexual assault, murder, and robberies. It will also allow the identification of dead bodies in cases where it is difficult to identify the dead person due to unrecognizable condition of the body. This study will facilitate the improvement of the investigation of crime scene investigators. It will provide a significant way for the incorporation of recent techniques of the molecular genetics into forensics. Reduction in the workload of the crime scene investigators would also occur through the implementation of outcomes of this study into the field of forensic science. There are several studies which have demonstrated the applicability of SNPs in forensic investigations for identifying the humans at crime scene. Several effective and efficient technological systems have been developed by the researchers which are capable of performing analysis of biological samples containing degraded DNA because SNPs can be obtained from these samples. Physical characteristics of the individuals can be predicted through the analysis of SNPs. This can provide significant information about the color of eye, hair and skin of the individuals involved in crime.

AbstractOnce the body dies, the indigenous microbes of the host begin to break down the body from the inside and play a key role thereafter. This study aimed to investigate the probable shift in the composition of the rectal microbiota at different time intervals up to 15 days after death and to explore bacterial taxa important for estimating the time since death. At the phylum level, Proteobacteria and Firmicutes showed major shifts when checked at 11 different intervals and emerged at most of the postmortem intervals. At the species level, Enterococcus faecalis and Proteus mirabilis showed a downward and upward trend, respectively, after day 5 postmortem. The phylum-, family-, genus-, and species-taxon richness decreased initially and then increased considerably. The turning point occurred on day 9, when the genus, rather than the phylum, family, or species, provided the most information for estimating the time since death. We constructed a prediction model using genus-level data from high-throughput sequencing, and seven bacterial taxa, namely, Enterococcus, Proteus, Lactobacillus, unidentified Clostridiales, Vagococcus, unidentified Corynebacteriaceae, and unidentified Enterobacteriaceae, were included in this model. The abovementioned bacteria showed potential for estimating the shortest time since death.

Insight Into

Postmortem studies are crucial for providing insight into emergent diseases. However, a complete autopsy is frequently not feasible in highly transmissible diseases due to biohazard challenges. Minimally invasive autopsy (MIA) is a needle-based approach aimed at collecting samples of key organs without opening the body, which may be a valid alternative in these cases. We aimed to: a) provide biosafety guidelines for conducting MIAs in COVID-19 cases, b) compare the performance of MIA versus complete autopsy, and c) evaluate the safety of the procedure. Between October and December 2020, MIAs were conducted in six deceased patients with PCR-confirmed COVID-19, in a basic autopsy room, with reinforced personal protective equipment. Samples from the lungs and key organs were successfully obtained in all cases. A complete autopsy was performed on the same body immediately after the MIA. The diagnoses of the MIA matched those of the complete autopsy. In four patients, COVID-19 was the main cause of death, being responsible for the different stages of diffuse alveolar damage. No COVID-19 infection was detected in the personnel performing the MIAs or complete autopsies. In conclusion, MIA might be a feasible, adequate and safe alternative for cause of death investigation in COVID-19 cases.

AbstractAn isolated burial was excavated from the bank of a tributary of Gordon Creek, Roosevelt National Forest, northern Colorado. A preliminary report was prepared (D. Anderson 1966, 1967) but further analysis of the skeletal material and newly obtained cultural information add significantly to the documentation of the burial.The body of a woman, aged 25-30 years, was given primary interment in a pit coated with red ocher. The body was placed on its left side with the head to the north, was tightly flexed, and was also coated with red ocher. Burial accompaniments include a large precussion flaked biface or preform, a small biface used as a scraping tool, a hammerstone, an end scraper, a preform with fire pocks, cut and incised animal ribs, and a perforated elk incisor. A radiocarbon assay of bone material from the left ilium produced an age of 9700± 250 radiocarbon years: 7750 B.C. (GX-0530).No indications of habitation which might be associated with the burial were located in its immediate vicinity.A reconstruction of the burial ritual is attempted, and the skeletal remains are compared to other early human remains from North America.A summary of this paper was given at the 34th Annual Meeting of the Society for American Archaeology, May 3, 1969, in Milwaukee, Wisconsin.
