Abstract: Sex estimation is the first step in the analysis of found human remains, this can collaborate or disprove a forensic case, and can also then help to provide an age of remains at death to begin a timeline. Results are created from many methods however these methods have their own pros and cons, for example if only part of a full skeleton is found some methods are not plausible. The results established show that the skeletons in question (216 and 889) are both full enough to create a decision in this case, however one decision was created easier than the other.
Forensic Anthropology is a multidisciplinary field combining physical anthropology, archaeology and other fields of anthropology with forensic science, including forensic dentistry, pathology and criminalistics – (Iscan 1981). Combining forensic anthropology and human osteology – the study of human bones, forensic scientists use many methods to estimate the sex of human remains. This is a highly important topic to any type of forensic specialist as it can

The first measurement been the;
(Ischium Length / Pubis Length) x 100 and the result is how you can go to putting the skeleton on the scale. These measurements are determined by taking the ischium length using callipers - an instrument for measuring internal or external dimensions, consisting of two steel legs hinged together. (Collins English Dictionary no date) and the pubis length is measured using the same method.
The next measurement would be;
Maximum ant sacral breadth x 100 / Max ant sacral height, and the result scoring once again fitting in a range to scale – these scores shown in results section
Finally, the last metric measurement of the pelvis is;
Greater sciatic notch width x 100 / Vertical diameter of the acetabulum.
These methods, metric and morphological, where checked on both skeletons that I performed a sex estimation on and results were created if
The skeleton had a hideous impact to the community and was predicted by local investigators to be reasonably modern. To get better understanding and avoid confusion, a bone sample was sent to a laboratory in the USA for investigation and analysation using series of scientific

...vejoy, the team’s anatomy expert, hypothesized that the bone crushed and fossilized misshapen, causing the position of the bones to seem as if they “flared up like a chimp’s.” This initial conclusion might have been the correct one, but Lovejoy was part of Johanson’s team, and as such, his analysis was done under Johanson’s influence. Johanson concluded that this chimp-like bone was an illusion, and the reconstruction that followed resulted in a bipedal pelvis. It is unclear how certain the researchers can be that the final result was the original shape of the bone, but one thing is clear – the reconstruction was done under the influence of the initial and final conclusion. When the assembly and analysis of the bones are done by a team of researchers already pre-disposed to a specific hypothesis, it is little wonder that the evidence ends up fitting the hypothesis

Therefore, the criminal justice system relies on other nonscientific means that are not accepted or clear. Many of forensic methods have implemented in research when looking for evidence, but the methods that are not scientific and have little or anything to do with science. The result of false evidence by other means leads to false testimony by a forensic analyst. Another issue with forensic errors is that it is a challenge to find a defense expert (Giannelli, 2011). Defense experts are required to help the defense attorneys defend and breakdown all of the doubts in the prosecutors scientific findings in criminal cases. Scientific information is integral in a criminal prosecution, and a defense attorney needs to have an expert to assist he/she in discrediting the prosecution (Giannelli,

Biological anthropology is broken into six branches, paleoanthropology, human osteology, human biology, anthropological genetics, forensic anthropology, and primatology. Primatology is the scientific study of primates, both living and extinct. Since we ourselves are primates it is natural that we should understand how they communicate and interact with their young. It could help us gain insight into why we act the way we do with our off spring. Our bones can tell us a lot about ourselves; even a simple measurement can be essential for identifying stature and growth patterns. These studies of osteology can help us better determine the health of the bone structure in infants. Something as simple and easy as measuring a forearm and help prevent a life threatening illness from causing a young one’s death before any symptoms become apparent.
In today’s time, modern Crime Scene Investigation has increased rapidly. From throughout the late 1900’s and in the early 2000’s (Taylor 1). For all of the evidence that they find, a solid foundation has formed over the thousands of years of Crime Scene

Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime scene.
Homo erectus is also known for its larger body compared to earlier ancestors. "Past estimates of Homo erectus stature frequently were in the 5-5 1/2 feet (152-168 cm) range for adult males and arou...
The transitional growth in the forensic science sector has not been without challenges. Though the world has experienced increased capabilities and scientific knowledge, which has led to faster investigations and results, many forensic experts have argued that forensic laboratory testing, in the light of 21st century technological advancements, is yet to meet the expected rate in quick available testing and analysis (Mennell & Shaw, 2006). This is with respect to the growing rate of crime and the high demand of quick crime scene testing and analysis. In the science of crime scene, analysis and interpretation of evidence is majorly dependent on forensic science, highlighting the change in the role of forensic sciences (Tjin-A-Tsoi, 2013). In the business of forensic science, time is beginning to play important role in the evidence testing and analysis which is becoming crucial in reducing ...
The topic I find such fascinating is Forensic Science and how forensic science has significantly changed over the years. “The area of forensic science has grown considerably over the last 150 years and more so since the mid 1980’s.” (Lyman, 2016) Forensic science has gone from taking basic information, and fingerprints to DNA and blood splatter. During a crime scene investigation evidence is collected, analyzed in a crime laboratory and then if needed are presented to the court. However, today the crime laboratory is becoming mobile and can go to the scene to analyze the evidence. Each crime scene and investigation is unique and distinctive, with the help of forensics it can help solve a case.
