what are the three kinds of evidence thet archeoligists study?

They study human skeletons, artifacts, ancient agricultural patterns, hearths, remains (such as animal bones) of food, and ruins of ancient buildings.

Thanks! But that's more than 3. Is there 3 main ones?

You're welcome. Please check your book to find what its author believes are most important. Oh -- and another thing that archaeologists study is graves and the goods that were buried with the people. (Think King Tut's tomb.)

Also, what is culture? and what does it include?

This is probably the definition you want.

"6. Anthropology. the sum total of ways of living built up by a group of human beings and transmitted from one generation to another."

Archaeologists study various types of evidence to understand and reconstruct past human cultures and behaviors. The three main categories of evidence that archaeologists study are:

1. Artifacts: These are objects created, modified, or used by humans in the past. Examples include tools, pottery, weapons, jewelry, and everyday items. Artifacts provide direct insights into the skills, technology, economy, aesthetics, and daily lives of the people who made or used them.

To study artifacts, archaeologists conduct excavations and carefully recover and document the objects they find. They analyze the materials used, manufacturing techniques, and patterns of distribution to determine their age, function, cultural significance, and meaning.

2. Ecofacts: These are natural remains that provide information about the environment, including plant and animal remains. Ecofacts can include plant seeds, animal bones, shells, pollen, and charcoal. By examining ecofacts, archaeologists can reconstruct past ecosystems, diets, agricultural practices, and environmental changes.

To study ecofacts, archaeologists collect samples from archaeological sites and use methods such as flotation to recover botanical remains and sieve soil to find tiny artifacts like fish or bird bones. They then analyze these remains using various scientific techniques such as microscopy, radiocarbon dating, or stable isotope analysis.

3. Features: Features are non-portable archaeological structures or remains that cannot be easily moved. These can include hearths, building foundations, walls, postholes, ditches, or burials. Features provide information about architecture, settlement patterns, land use, social organization, and rituals.

To study features, archaeologists excavate and map them in detail. They document their sizes, shapes, orientations, and relationships to other features or artifacts. Through careful analysis and comparison with other sites, they can interpret the function, meaning, and significance of these features within a specific cultural context.

In summary, archaeologists study artifacts, ecofacts, and features to reconstruct past human cultures and behaviors. By analyzing these different types of evidence, they can gain insights into various aspects of ancient societies, ranging from technology and subsistence strategies to social organization and belief systems.
