Human Hair Vs Animal Hair | Forensic Science Notes

To get notes, visit my website: https://forensicsciencehub.com Hello everyone! In the above video i have discussed about the major points that can help us differentiate whether the hair found at the crime scene is of human origin or animal origin. Human and animal hairs have been used in forensic investigations for over a century. Hair is stable under adverse natural conditions; hence, it is often recovered at the crime scene, and it is necessary to determine whether the hair is of human or animal origin. Morphological and genetic characteristics are useful to differentiate human hair from animal hair. Differences between animal and human hair may include 1. Color-human hair is more continuous in coloring versus pet hair is often banded. 2. Pigment concentration: Human hair has even distribution of pigment throughout cortex, while animal hair is more concentrated toward the center/medulla area. 3. Medullary Index: Animal hair ratio of medulla to shaft diameter is much greater than humans 1/3 or more the width of the shaft! 4. Cuticle patterns: Human hair is imbricate pattern, while animals can have a range including coronal and spinous. For More info Subscribe now...
