2. INTRODUCTION FOR FORENSIC SCIENCE: Forensic science is a multidisciplinary field that combines principles of various scientific disciplines to investigate and analyze evidence related to legal cases. The term "forensic" is derived from the Latin word "forensic," meaning "of the forum" or "pertaining to the court." Forensic science plays a crucial role in the criminal justice system by providing objective and scientific analysis to support investigations, legal proceedings, and the pursuit of justice. The primary goal of forensic science is to uncover the truth by examining physical evidence and applying scientific methods to answer questions related to crimes, accidents, or legal disputes. This field encompasses a wide range of scientific disciplines, including but not limited to biology, chemistry, physics, anthropology, and computer science. Forensic scientists use their expertise to collect, preserve, and analyze various types of evidence, such as blood, hair, fingerprints, DNA, digital data, and more. The findings are then presented in a court of law, aiding investigators, attorneys, and judges in making informed decisions.

HISTORY AND DEVELOPMENT OF FORENSIC SCIENCE Ancient Civilizations: China (c. 1248-1224 BCE): The first recorded use of forensic science dates back to the ancient Chinese legal text " Hsi Duan Yu" (The Washing Away of Wrongs), which described the examination of corpses to determine the cause of death. Roman Empire (c. 44 BCE - 410 CE): In ancient Rome, physicians such as Galen were involved in examining wounds and injuries. The legal system utilized rudimentary forensic methods for investigating crimes. Middle Ages: During the Middle Ages, medical practitioners began to play a role in forensic investigations. Autopsies were performed to determine the cause of death, and some early forensic techniques were employed. Renaissance (14th-17th centuries): The Renaissance saw advancements in anatomy and medicine, which contributed to the understanding of the human body. However, forensic science as a distinct discipline had not yet emerged.

7. 4. 18th Century: Mathieu Orfila (1787-1853): Often considered the father of forensic toxicology, Orfila made significant contributions to the field by developing methods for detecting poisons in the human body. 5. 19th Century: Alphonse Bertillon (1853-1914): Bertillon introduced anthropometry, a system of body measurements, as a method of identifying individuals. This was later replaced by fingerprinting but marked an early attempt at systematic identification. Francis Galton (1822-1911): Galton's work on fingerprints and their uniqueness laid the foundation for the use of fingerprint analysis in forensic science. Sir Arthur Conan Doyle (1859-1930): Although a fiction writer, Conan Doyle's fictional detective Sherlock Holmes popularized the use of scientific methods in solving crimes.

8. 6. Early 20th Century: Edmond Locard (1877-1966): Locard formulated the " Locard's Exchange Principle," stating that every contact leaves a trace. He founded the first forensic laboratory in Lyon, France, in 1910. Fingerprinting: Fingerprint identification became widely adopted as a reliable method for personal identification. Sir Edward Henry's fingerprint classification system was instrumental in standardizing the practice. 7. Mid to Late 20th Century: DNA Profiling: The discovery of the structure of DNA by James Watson and Francis Crick in 1953 laid the groundwork for DNA profiling, a revolutionary development in forensic science. Sir Alec Jeffreys developed the first DNA fingerprinting technique in 1984.

9. 8. 21st Century: Digital Forensics: With the rise of digital technology, forensic science expanded to include digital forensics, focusing on the examination of electronic devices and digital evidence. Interdisciplinary Approach: Modern forensic science is characterized by an interdisciplinary approach, combining expertise from various scientific fields such as biology, chemistry, physics, and computer science. 9. Challenges and Advances: Forensic science has faced challenges related to the reliability of some techniques and the need for standardization. Ongoing research and advancements aim to address these challenges and improve the accuracy of forensic analyses.
