Step-by-step explanation:
Physical Anthropology is d) the study of the physical and biological nature of human beings. As a branch of anthropology, this field focuses on the adaptation, variability, and evolution of humans and their living and fossil relatives. Physical anthropologists often hold academic appointments at universities and contribute to departments like anthropology, biology, genetics, or zoology. Their work encompasses various areas such as human biological variation, paleoanthropology, primatology, bioarchaeology, and genetic anthropology, to understand the origins, evolution, and diversity of our species.
Biological anthropology is a term often used synonymously with physical anthropology to denote the study of human origins and diversity. It offers insights into the biological and sociocultural development of human beings. This deeper look into our past helps to explore what it means to be human, examining both our past evolutions and current biological diversities.
Overall, anthropology, including its physical anthropology subfield, is a uniquely relevant discipline, providing comprehensive knowledge of human life. It investigates how we, as humans, engage with the world through our minds and bodies, and how we've adapted and evolved over time, highlighting the incredible diversity present within the human experience.
