"An Englishman, Sir Edward Henry, who had been given tuition in fingerprints by Galton, devised a workable classification system independently of Vucetich and implemented it in India in 1897. Henry published his book Classification and Uses of Fingerprints in 1900.
In 1901, Henry was appointed Assistant Commissioner of Police at New Scotland Yard and began to introduce his fingerprint system into that institution. By the end of that year, the Fingerprint Office at New Scotland Yard was fully functional, the first British court conviction by fingerprints being obtained in 1902. Approximately 10 years after the publication of Henry's book, his classification system was being used by police forces and prison authorities throughout the English-speaking world."
The Basic Structure that has to be followed for developing any Software/project including Testing process is called as Testing Methodology.
A prototyping methodology is a software development process which allows developers to create portions of the solution to demonstrate functionality and make needed refinements before developing the final solution.
Silver nitrate is commonly used for developing fingerprints on wood surfaces. The silver ions in the nitrate solution react with the components in the sweat residue left by fingertips, creating a visible mark that can be visualized under certain lighting conditions.

Even though identical twins share the same genetic makeup, their fingerprints are formed by the unique interactions between genetic factors and the environment in the womb. The positioning and movement of the developing fetus within the womb can result in differences in the pressure and patterns of skin ridges, leading to distinct fingerprints for each twin.
Carl Linnaeus is credited with developing the method for classifying organisms, known as the Linnaean system of taxonomy. He introduced the hierarchical classification system based on shared physical characteristics of organisms.
Ninhydrin is another common chemical used to develop fingerprints on porous surfaces like paper. It reacts with amino acids found in sweat to produce a purple color, making fingerprints visible. Magnetic powder and fluorescent powders are also effective alternatives to iodine for developing fingerprints on different surfaces.
Developing a methodology for a research study can be challenging due to several factors. Here are some common challenges researchers face: Defining the Research Problem Choosing the Research Design Sampling Data Collection Methods Data Analysis Ethical Considerations Time and Resource Constraints Literature Review Flexibility and Adaptability Communicating Methodological Choices
