Your Inner Fish - Book Report The book “Your Inner Fish” written by Neil Shubin takes us through his search and knowledge of fossils as a paleontologist. The main idea is well, finding your inner fish or in scientific terms tracing back the evolution from fish to land living animals such as mammals. Neil shares his experience looking for important fossils that reveal our evolution into humans.
In episode 5 “The Bones That Weren’t,” a skateboarder sneaks into a construction site and stumbles upon a human skull protruding from the recently poured concrete. While at lunch, Dr. Temperance Brennan and Booth receive a call about the findings at the construction site. Brennan determined that the skull belongs to a male in his late 20s. In the lab, the team was about to determine that there was only the skull in the concrete. With the use of a lab technique, they were able to create an image of the victim’s skeleton.
To start off with is the DNA samples, on the nightshirt which was saliva. They couldn’t analyze the DNA at that time because the technology didn’t exist. To expand on it there was DNA on the nightshirt but they couldn’t analyze with the technology back then. Next piece of evidence are the bite marks. Furthermore the bite marks on Sabina were analyzed by two different analyst.
It was a hominin molar. The team look through that area, and found the lower jaw of a child with an attached milk molar. The team knew that the molar they found was of a hominin both older and more primitive than Lucy. In November 1994, Yohannes Haile-Selassie found pieces of a bone from the palm of a hand. That discovery was followed by the finding of pieces of a pelvis, leg, ankle, and foot bones, many of the bones of the hand and arm, a lower jaw with teeth, and a cranium (Gibbons 37).
Dental trial have been extensively used in identifying the sufferers of massive disasters, such as the 9/11 bombing and the Asian tsunami. the significance of using dental records for human identification is now well predictable. Dental Biometric issues dental radiographs to identify victims in situations (e.g., fire victims) where conservative biometric features, i.e., face, fingerprint, and iris, are not available. Dental Photograph Dental photograph is a symbolic examination of teeth structure and its appearance; it gives virtual position of neighboring teeth and shapes of dental work.
The nonfiction book, Jumped, Fell, or Pushed: How Forensics Solved 50 “Perfect” Murders, is an informative and well written book by the author, Stephen A. Koehler. Okay, you get two options, take Mr. Laney’s forensic science class at Lincoln High School or read this book. If you don’t know anything about Forensics, this book gives a sufficient overview of the subject and its counterparts. There is no main plot or developing characters within the book. The type of evidence varies from chapter-to-chapter, as well as the forensic technique implemented to analyze that evidence.
In this paper I will be comparing contrasting two various aspects of forensic sciences used, and talking about the different tactics used to identify suspects; as well as the contrasts between the two methods. The man I will be talking about is John Wayne Gacy. The two methods I will be going over are, Finger print DNA and Forensic toxicology. These two are very similar, but made substantial differences in the evidence in his case. John Wayne Gacy was a murderer from Chicago, Illinois.
Bones are used similarly and have been compared to fingerprints. Bones have scratches or breaks that can help establish identity or determine how long one has been dead. They are also used in dismemberment cases to determine what type of saw was used. Bugs, specifically the coffin fly, can determine where a person died, and the different generations of maggots can tell how long one’s been dead. These many aspects of death and decomposition can answer many questions and almost solve the case by
In 1913, a case involving the identification of the remains of a man killed in a train accident was solved using dental evidence. The victim's dental records were compared to the teeth of the unidentified body, and a match was made. This case led to the development of a national database of dental records, which has since become a standard tool for forensic odontologists. During World War II, forensic odontology played a crucial role in identifying the remains of soldiers killed in battle as dental records were used to identify thousands of soldiers
A positive aspect of this is that forensic scientists only need a small amount of a sample to get the results they need (“Forensic Science” 12). These samples can come from many other forms of identification other than fingerprints and bloodstains. A few moderate examples include strands of hair, tiny beads of sweat, and a saliva specimen (“Forensic Science” 12). Forensic Science Technicians stated that “crime scene investigators may use tweezers, black lights, and specialized kits to identify and collect evidence.” They also stated that examining autopsies prove to be beneficial in a crime investigation (“Forensic Science Technicians”
A major crime scene, such as JonBenet’s, details where serious physical and/or emotional trauma is reported, this can include crimes such as murder, manslaughter, and rape (Standing Bear 1999). Due to the nature of a homicide, evidentiary findings can only be determined after a professional examination of the crime scene has occurred (Pepper 2010). The three principles to ensure an effective investigation is conducted includes: rapid response to the crime scene; to secure the scene before evidence is contaminated, damaged, lost or stolen. Secondly, gathering of evidence, all evidence at the crime scene must be preserved and noted whether physical or testimonial; in some cases, this can lead investigators straight to the perpetrator. Lastly, processing of the evidence; this includes putting together all available evidence to determine a verdict in court (Pepper 2010).
Throughout the book, it is notable that the author tries to depict how life was in the year of 1964, providing the reader important information about historical events that happened at the time. The story starts in the first of July, a day before the signing of the civil rights act. The author chose to utilize this date since it is an important clue about the historical background of the book, as the United States approaches towards the civil rights act. The signing of the civil rights act is definitely demonstrated in the scene where Rosaleen watches the news on the television. The news states that; "Today, July second, 1964," he said, "The president of the United States signed the Civil Rights Act into law in the East Room of the White House."
On the contrary, scientist began to unearth new fossils in Asia and Africa, that were thought to be human ancestors that came hundreds of thousands of years old after Piltdown Man. They were found to be less human with small skulls, but without authorization to the Piltdown bones and efficient dating methods, they were all but ignored because they contraindicated Eoanthropus dawsonii. It was not until 1949, when the bones were discovered to be around a hundred thousand years old; with the application of newly discovered fluoride dating. Subsequently, they were fully analyzed in 1953 and exposed as a hoax. Scientist discovered that the jawbone indeed came from a female orangutan and was less than 100 years old.
A problem with limiting investigations to people of certain ancestry is that people are frequently of mixed ancestry, which may result in contradicting information between what the police are looking for and the ancestry shown in the skeletal remains. In addition, forensic anthropologists are involved in studying taphonomy, which is the study of any activity that affects the remains since the time of death to the time it is discovered. This includes decomposition, approximate time since death, any interaction with the environment, and other organisms that affect the condition of the body. This is useful in determining an accurate biological profile from limited resources, as the human remains are not always in full skeleton form (Anderson,
The physical evidences are gathered at any crime scene, for example, hair, fibre, blood, fingerprints, footwear, bare-footprints, tire impressions and any fracture
