Final answer:
Bioarchaeologists and osteologists use skeletal evidence to reconstruct lifeways of past populations. Difficulties in interpreting this evidence include sample bias and limitations in the available material.
Step-by-step explanation:
Bioarchaeologists and osteologists use various types of skeletal evidence to reconstruct the lifeways of past populations, such as analyzing human remains to determine the age, sex, diet, health, and presence of diseases in individuals. For example, skeletal evidence of infant cranial boarding can provide insights into social identity. However, there are difficulties in interpreting this evidence, including the possibility of bias in the sample, limitations in the available skeletal material, and the challenge of distinguishing between different factors that may have influenced the observed skeletal characteristics.
