Final answer:
The concept of race is a social construct viewed from an anthropological perspective. There are no scientifically valid racial categories, as human traits vary along a spectrum. Racial categories have changed over time and have been used to exploit and marginalize certain groups.
Step-by-step explanation:
Race from an anthropological perspective is viewed as a social construct rather than a biological reality. Anthropologists emphasize that there are no scientifically valid racial categories because human traits, such as skin color, vary along a spectrum and are mixed among populations. The concept of race has changed throughout history, becoming less connected with ancestry and more focused on superficial physical characteristics. Racial categories have been used to exploit and marginalize certain groups, but people have also responded with resilience and cultural forms of resistance.
