Historically, hair has been considered class evidence because a hair specimen could not be identified with certainty as having originated from a particular person. A forensic scientist who studied the morphology (shape, form, and structure) of a hair specimen could testify as to the gross physical characteristics of the hair (color, degree of curl, etc.), its internal and external structural characteristics, the likely somatic region from which the hair originated (scalp, beard, pubic, axillary, etc.), and–at least for scalp hair, and often for pubic hair, the probable race of the person from whom the hair originated. But all of those are class characteristics rather than individual characteristics, so the most the forensic scientist can state based on morphological examination is that a hair specimen is “consistent with” or “similar in all respect to” another specimen.
They are different because a forensic chemist studies and tests chemicals and drugs and a forensic toxicologist studies poisons with criminal justice cases
The Anglo-Saxons were a cultural group who inhabited England in the Early Middle Ages. They traced their origins to the 5th century settlement of incomers to Britain, who migrated to the island from the North Sea coastlands of mainland Europe. Some sources say that the Saxon warriors were invited to come, to the area now know as England, to help keep out invaders from Scotland and Ireland. Another reason for coming may have been because their land often flooded and it was difficult to grow crops, so they were looking for new places to settle down and farm.
