What can be used as human remains in bioarcharology? - CORRECT ANSWER- ✔✔-bones
-flesh and tissues (rarely preserved)
- the shape of the bodies after they have disappeared.
- cremations
How can archaeologists determine the sex of human remains in bioarchaeology? -
CORRECT ANSWER- ✔✔- size; body dimorphism
- specific bones such as the pelvic bone
How can it be difficult to determine the sex/age of children? - CORRECT ANSWER- ✔✔the
body morphology doesn't apply to children because their body and bone structures have not
developed fully yet.
How can archaeologist determine the age of an individual? - CORRECT ANSWER- ✔✔-
teeth (teeth eruption patterns, growth rings)
- bone fusion (with age, the bones begin to fuse together)
- plates on the skull (the skull increases in thickness as we age).
What is paleopathology? - CORRECT ANSWER- ✔✔a way to look at ancient
