Recommended: When was fingerprinting first used
Everyone has their own fingerprint that is special to their DNA. Fingerprints can be used to unlock phones, so solve crime scenes and many other things. The purpose of this science fair paper leads to one question, can your fingerprint show your heritage? Fingerprints are based on the person's skin pattern and ridges which are also known as dermatoglyphs. Those ridges are found on feet, palms, and especially the top half of fingers. These dermatoglyphs develop well before birth and stay the exact same throughout people's lives. Dermatoglyphs are fully developed for the baby's body in the sixth month of pregnancy. These dermatoglyphs are not fully based off DNA, part of it is the condition of the womb for the baby in pregnancy. There are

Deoxyribonucleic acid (DNA) is an acclaimed extraordinary discovery that has contributed great benefits in several fields throughout the world. DNA evidence is accounted for in the majority of cases presented in the criminal justice system. It is known as our very own unique genetic fingerprint; “a chromosome molecule which carries genetic coding unique to each person with the only exception of identical twins (that is why it is also called 'DNA fingerprinting ')” (Duhaime, n.d.). DNA is found in the nuclei of cells of nearly all living things.
When it comes to identical twins we have come to learn that twin identical or not will not have the same fingerprint. Fingerprints are unique and are made to identify a person. So even when you clone humans or other primates I believe that the Friction ridge pattern will be similar but not exactly the same. I believe that in the process of the cloning process something will cause the fingerprints to come out different. Because cloning is dangerous there has yet to be a human cloning, but there have been cloning of monkeys and according to the data even though the monkey was cloned the fingerprint still isn’t the same.

DNA fingerprinting, or sometimes known as DNA typing, is isolating and developing images of sequences of DNA to evaluate the DNA in an individual’s cells. DNA fingerprinting today is used for many different things in many different areas of science. In forensic science, DNA typing can determine which person did which crime by using blood or skin left at a crime scene. In medical science, patients can find out who their siblings, parents, or children are by using DNA fingerprinting (webmd).
FINGERPRINTS HOLD CLUE TO ANCESTRY Jessica Firger published an article discussing fingerprints as a key factor in identifying people since they are unique to every individual. Previously, Firger states, fingerprints were used by anthropologists as a means to simply learn about basic identity traits. Researchers believe that they can now identify ancestry based on fingerprinting. A study conducted showed a link between determining sex and ancestry through the use of fingerprinting, and is published in the American Journal of Physical Anthropology, she points out.
DNA, or deoxyribonucleic exists in all living organisms, is self-replicating and gives a person their unique characteristics. No two people have the same matching DNA. There are many different forms of DNA that are tested for situations such as criminal. Bodily fluids, hair follicles and bone tissues are some of the most common types of DNA that is tested in crime labs today. Although the discovery of DNA dates back to 1866 when Gregor Mendel proved the inheritance of factors in pea plants, DNA testing is relatively new and have been the prime factor when solving crimes in general. In 1966, scientists discovered a genetic code that made it possible to predict characteristics by studying DNA. This lead to genetic engineering and genetic counseling. In 1980, Organ was the first to have a conviction based off DNA fingerprinting and DNA testing in forensics cases became famous in 1995 during the O.J. Simpson trial (SMC History , 2011).
Imagine going to a crime scene every day and picking up evidence. You then take the evidence back to the lab to investigate it. Not only that, the scene must be reconstructed and evidence used to catch a perpetrator. Once you figure it out, the case must be presented in court. That’s all in a day’s work.

“DNA was discovered in 1868”, around the same time that the laws of heredity were being written by Gregor Mendel which laid the foundation for the modern science of genetics. A major break through which eventually made possible forensic uses of DNA occurred in the early 1950’s when James Watson and Francis Crick solved the puzzle of DNA’s structure and precipitated the revolution in molecular biology which followed. By solving the puzzle they made this foundation of our modern DNA analyzes used in today’s forensic science. (2)
People from various parts of the world have different features that can be used to identify where they originate. The question of whether or not human races truly exist is now a prevalent one in the scientific community. Some scientists believe that race is biologically meaningless while others believe that race can be used to determine medical treatment for a person (Jorde & Wooding, 2004). Although there are genes that determine the different physical characteristics of people their genetic variation is mainly due their geographic location. There is some biological basis for the phenotypic differences in humans, but the way we define and understand these differences are flawed. There is no individual trait or gene that separates members of one race from all the members of another race (Brace & Gill, 2000).
The first recorded use of biometrics dates back to the 14th century when the Spanish explorer Joao de Barros witnessed Chinese parents pressing their children’s inked fingers and feet onto paper allowing them to differentiate one child from another. Through Barros’ travels, he noted that Chinese businessmen also closed various financial and business transactions with fingerprints. There are other pieces of historical evidence indicating the use of biometrics for various purposes prior to Barros’ records. However, none were successfully documented.
Fingerprint usage dates back to the 1800s. Sir William Herschel used the prints as signatures on civil contracts, before they were found useful towards crimes (History of Fingerprints Timeline, 2012). A British surgeon, Dr. Henry Faulds, wrote about using fingerprints for personal identification. He first looked at prints on clay pottery and studied the ridges and patterns that they had made in the clay. In 1891, Juan Vucetich suggested to start fingerprinting criminals to keep the prints on record. The following year, Vucetich identified a print from a woman who killed her two sons. Investigators found her print and were able to correctly match her identity. Charles Darwin’s cousin, Sir Francis Galton, wrote and published the first book about fingerprints. He wrote about how every individual has a unique print by the certain traits of each fingerprint (History of Fingerprints, 2012). The popularity of fingerprints grew greatly in the United States in the early 1900s. Police departments and the FBI began to use the...
A nail, a short or a long piece of metal, brass or copper that gets hit on the head with a hammer, can be used for so many different purposes. Construction workers, a builder or even a handyman uses nails for building houses, building items such as a bird house or a shed, and even building furniture and making home repairs. I am someone who enjoys hands on activities and I absolutely love building things and a nail is my best friend because without a nail, what would hold a house together? A simple nail is often taken for granted, and does not get the credit it deserves, from its role in history, its many different uses and its role in ultimately helping to shape the world today.
A thousands years ago until now, human use their physical and behaviour characteristic to recognize such as face, voice, . However, in the middle of 19th century, chief of the criminal identification division of the police department in Paris, Alphonse Bertillon, had idea to use body measurements to identify crime. In late 19th century, it was identified with the discovery of far more important and practical distinctiveness of human fingerprint. Soon after this discovery, many departments have applied the idea of fingerprints especially law enforcement against crime and keep the information in the database (actually, file cards). Today’s One of the way is biometric technologies.
