This is the study of people and their history through the study of things left behind by humans in the past. People who study archaeology are called archaeologists. They dig up sites where people used to live, or where they left things behind. These include human bones, ancient buildings, ancient trash heaps and more.
The most famous archaeological sites, such as Egyptian tombs, tend to be very old. But the sites don’t have to be all that ancient. Some archaeologists study landfills and other sites that are only a few decades old. Their findings can help us learn new things about our history and our society.
Archaeology is not the study of ancient animals. Most of the time, that’s paleontology. But sometimes, scientists study remains of animals that lived with humans — such as ancient dogs, cats or cows. Then it’s called zooarchaeology.
