22. Review & Reflect #1 (Page 10) What have scientists learned from uncovering ancient fossils? Why is this important?
From ancient fossils, scientists have learned:
• the origins of humans and other species
• the story of human evolution
• how humankind lived
• about the tools that humans used and how they used them
• how long humans have inhabited the earth
• about the timeline of human evolution
It is important to study ancient fossils because they reveal things about the human species and relate them to the modern world. These fossils help scientists understand the links between all humans today.
