Why do archaeologists sift through the remains of ancient composite?
Archaeologists sift through the remains of ancient composites in hopes of finding artifacts or other bits of evidence that will help them to find out what they want to know.
Archaeologists typically look for things that tell them about the people they are studying. They may be looking for things the people made, such as tools or clothing. They can hope to find fragments of these by sifting the soil. They may also be looking for evidence of what the people ate. They might then sift in hopes of finding pieces of bone or of vegetable matter.
