Final answer:
Skeletal remains are important for understanding the lives of past humans due to the information they provide about individuals. By studying skeletal material, researchers can gain insights into mortality patterns and conduct studies on human evolution.
Step-by-step explanation:
Skeletal remains are relevant to research into the lives of past humans because they are a group of records that provide valuable information about the individual's life. Unlike written records that may be missing or biased, skeletal material offers direct evidence about mortality patterns and can reveal important information about the individuals who lived in the past. By analyzing the physical morphology of skulls and other skeletal remains, paleoanthropologists can form hypotheses about important milestones in human evolution over time.
