5. Observations
Observation is one of the skills used by a special group of scientists who study prehistory.
These scientists are called archaeologists, and we know about the distant past through their studies.
The skeleton they are studying is one of their significant discoveries, and you will figure out why it was so significant.
What did you notice about Lucy.
Archaeologists, just like other scientists, form hypotheses or develop questions that they try to prove with evidence.
Archaeologists wanted to know what came first in human history—bigger brains or the ability to walk upright. Archaeologists had to look for evidence in the fossil record. Lucy was the fossil that answered their question.

6. Big Brains/Walking Upright.
Lucy
Modern Skeleton
Compare and contrast the modern skeleton with Lucy’s skeleton.
Using what you notice about both skeletons, add evidence to their T-chart that supports a hypothesis about which came first: walking upright or bigger brains.
• Draw a conclusion about which came first based on your observations.
