DIGGING UP THE PASTLesson 1 Continued

HISTORY AND SCIENCE (WHO STUDIES WHAT)

Archeology- the study of past by looking at what people left behind

Artifacts- objects made by people (ancient artifacts include tools, weapons, and pottery)

Fossils- remains of plants and animals that have been preserved from an earlier time

Paleontology- study fossils to learn what the world was like long ago

Anthropology- study of human culture and how it developed over time

HUMAN DISCOVERIES Lucy- Human ancestor fossil discovered

Ethiopia (located in Eastern Africa), her remains are over 3.2 million years old

The discovery of Lucy is important because she walked upright on two legs (bipedal)

She lived long before homo sapiens (modern humans)

Homo sapiens developed as a species (a class of individuals with similar physical characteristics)

Scientist have found nearly 40% of Lucy’s skeleton.

In 1992 an older fossil was found in Ethiopia, “Ardi” is dated to be nearly 4 million years old!
