Prehistoric Man Human Evolution - What Do Fossils Tell Us?

The video explores the significance of archeological sites and fossils in understanding Earth's past. It highlights the contributions of the Leakey family to paleoanthropology, particularly in East Africa. Various fossil dating methods, such as potassium-argon dating, are discussed. The video also covers excavation techniques and the challenges faced in archeological digs. The Leakeys' legacy in advancing knowledge about human evolution is emphasized.

• Photographing the fossils

• Using chisels and trowels to dig

• Numbering each item found

What can measurements of bones tell us about ancient individuals?

• Their exact age

• Their language skills

• Their favorite food

• Their build, height, and possible injuries
