Methods of Studying the Human Past
-What are fossil localities and archaeological sites, and how are they found?
-How are these localities and sites investigated?
-How are fossil remains and archaeological remains dated?
-A portable object made or modified by humans; something you can carry.
-E.g., tools, art objects, etc.
-A non-portable object made or modified by humans; something you can’t carry with you.
-E.g., hearth, living floor, storage pit, cemetery, etc.
-Natural objects that have been used by humans and are incorporated in an archaeological
-E.g., bones, seeds, wood, antler, shell, etc.
Ecofacts: Evidence of Domestication
-Selective breeding can be seen in plant remains at sites:
-E.g., wild cereal grasses (barley, wheat, corn, etc.) have a very fragile stem
-Tough-stemmed grasses indicates domestication (easier to harvest)
-Domesticated plants usually larger than wild forms.
-Trace or impression of an ancient organism preserved in rock, or actual mineralized remains.
-Involves the hard parts of an organism: bones, teeth, shells, horns, and the woody tissues of plants.
