Study Notes
Studying Prehistory
- Prehistory refers to the period before people began keeping written records, which is around 5,000 to 6,000 years old.
- Scientists study prehistory using evidence left behind by ancient people, such as tools, drawings, pottery, weapons, jewelry, and other objects.
- The earliest part of prehistory is known as the Stone Age, named for the use of simple stone tools and weapons.
Studying Prehistoric Evidence
- Scientists from diverse fields contribute to the study of prehistory:
- Archeologists study places where prehistoric people lived, looking for remains of homes, graves, and towns, and examining artifacts found there.
- Anthropologists study artifacts, bones, and other clues to determine physical characteristics, diet, lifespan, and other aspects of ancient cultures.
- Geologists analyze fossils and the surrounding rocks to understand the environment and time period.
- Botanists and zoologists provide knowledge about plants and animals that existed during prehistoric times.
Archeological Digs
- Archeological digs are sites where ancient objects are buried and excavated to understand the past.
- Sites are chosen based on clues like ground shape, local stories, or traditions, sometimes even accidental discoveries of artifacts.
- Digs are meticulously planned and executed:
- Sites are mapped with numbered squares for accurate recordkeeping of artifact location.
- Soil is removed layer by layer, carefully brushed to avoid damaging artifacts.
- Soil is sifted through screens to recover even small objects.
- Artifacts are photographed, labeled, cleaned, and studied to classify and identify them.
- Fragments are meticulously reconstructed, and drawings are created to show the original form.
- Samples of soil, clay, and paint are analyzed in laboratories to reveal further information.
Carbon-14 Dating
- Carbon-14 dating is a scientific method used to determine the age of organic materials like wood, bone, or other once-living things.
- It was discovered in 1948 by Willard Libby, who later won the Nobel Prize for this discovery.
- The method relies on the fact that all living organisms contain carbon-14, a radioactive isotope.
- When an organism dies, the carbon-14 decays at a constant rate.
- Analyzing the remaining amount of carbon-14 allows scientists to estimate the age of the specimen.
- Other radioactive elements can also be used for dating purposes.
