Title: Forensic Anthropology


1
Forensic Anthropology
  • Courtney Kelly
  • Evolution
  • Dr. Tietjen
  • Spring 2005

2
Anthropology
  • Study of humans
  • Concerned with all humans at all times with all
    human dimensions.
  • Human species evolved with a universal capacity
    to conceive the world.

3
Physical Anthropology
  • Also known as biological anthropology.
  • Study of primate order past and present.
  • Population genetics.
  • Human evolution including skeletal biology and
    human adaptation.

4
Cultural Anthropology
  • Social or Socio-cultural anthropology.
  • Study social networks, social behavior, kinship
    patterns of specific group.
  • Laws, religion and belief of culture.

5
Linguistic Anthropology
  • Study of language variation across space and
    time.
  • The social uses of language.
  • Relationships between languages and cultures.

6
Archaeology
  • Study artifact and material remains of human
    societies.
  • Analyze pollen, soil, seeds and insects found at
    excavation site.

7
Anthropology in the United States
  • Pioneered by John Powell and Frank Cushing
    working in the Smithsonian and Bureau of Indian
    Affairs.
  • Academic Anthropology founded by Franz Boas
  • Boasian anthropology was empirical and skeptical
    of over generalizing universal law.
  • World full of distinct cultures and each culture
    needed to be studied.

8
Forensic Anthropology
  • Its the application of physical anthropology to
    the legal process.
  • Identify skeletal, badly decomposed or
    unidentified human remains for legal and human
    reasons.
  • Started during the 19th century, popular during
    1930s because of WWII and the Korean War.

9
Fields within Forensic Anthropology
  • Osteology - specific study of bones.
  • Dentition study of tooth remains.
  • Ethnobotany study of pollen and plant remains.
  • Determine if remains are human, and then what the
    age, sex, race and stature.

10
The Skeleton
  • Metric traits traits that can be measured.
  • Examples femur or humerus bone lengths,
    diameters or bone densities.
  • Non-metric traits traits that can not be
    measured.
  • Examples fusion points in the skull.
  • Skull most structure used to determine if remains
    are human.

11
Sex Determination
  • No sexual dimorphism in young until puberty.
  • Possible with adolescent or adult skeletons.
  • Size between bones generally determine if remains
    are male or female.
  • Male chins are squarer, and have a more
    prominent brow ridge and eye socket.
  • Female chins are more rounded, with a rounded
    forehead.

12
  • Subpubic angle
  • Females greater than 90
  • Males less than 90
  • Sciatic notch
  • Females more than 68
  • Males less than 68
  • Sacrum is straighter in women than in men.

13
Age Determination
  • Preneonates and neonates size and lack of fused
    bones.
  • Infants and young children teeth and bone
    ossification and size.
  • Older children permanent teeth and amount of
    bone ossification.
  • Adolescents long bone length increases with
    fusion at ends.

14
Age Determination - Adults
  • Cranial sutures fuse together.
  • Rib-ends become ragged and cartilage becomes
    pitted.
  • Microstructure of bone and teeth.
  • Wear on teeth.

15
Skeletal Race
  • Difficult because of many blends of races.
  • Caucasoids triangular nasal hole.
  • Negroids square nasal hole, pronounced
    inversion of ramus.
  • Mongoloids diamond-shaped nasal hole.

16
Facial Reconstruction
  • Over 80 measurements in the skull.
  • Plasteline strips and pegs tell key features.
  • Clay is added to smooth out the surface and give
    a layer of skin.
  • Developed by Mikhail Gerasimov
  • Faces for Ivan the Terrible
  • Mongol warrior Tamerlane, Ulu-Beg, and other
    figures from Timurid Dynasty.

17
Conclusion
  • Forensic anthropology is a growing field
    requiring the culmination of many areas of study.
  • Human skeleton gives clues about humans both past
    and present.
