Features inherited from generation to generation are expressed in the morphology (shape) of the human skull. Many of these characteristics have evolved in response to environmental factors. Analysis of the Europea Asian African features of the skull can thus give an n indication of the ancestry of an individual. Skulls can be classified according to 3 biological backgrounds:  Ancestral Characteristics European Asian African Teeth can provide clues such as diet, hygiene and age The skull can reveal clues about a person’s death. The four cuts at the top of this skull "are clear chops to the forehead," says Smithsonian forensic anthropologist Douglas Owsley. Based on forensic evidence, researchers think the blows were made after the person died. Donald E.
