Which branch of anthropology studies the evolution of homo sapiens and physical variations among humans?

The branch of anthropology that focuses on the evolution of Homo sapiens and the physical variations among humans is Physical/Biological Anthropology. This field examines the biological and genetic aspects of humans, including their evolutionary history, adaptation to environments, and the study of human fossils and their relationship to contemporary human populations. It encompasses the study of human evolution, primatology, and the biological aspects of human variation, such as differences in morphology and genetics among populations.

Cultural Anthropology, in contrast, primarily investigates cultural practices, beliefs, and social structures, making it less focused on physical or biological aspects. Linguistic Anthropology explores the relationship between language and culture, while Applied Anthropology exists to apply anthropological knowledge to practical problems, which may include social issues, health, and education but does not specifically focus on evolution or physical variations. Therefore, Physical/Biological Anthropology is the appropriate choice for studying the evolution and biological diversity of humans.
