Physical Anthropology, also known as Biological Anthropology, is a branch of anthropology that deals with the study of humans as biological organisms, their evolution, variation, and adaptation in different environments over time. The aim of Physical Anthropology is to understand the biological and physiological aspects of human beings, their development through evolutionary processes, and how they interact with and adapt to their surroundings. Unlike cultural anthropology, which focuses on human society and culture, Physical Anthropology emphasizes the physical form, biological functions, and genetic makeup of humans, as well as the comparison of humans with other primates to understand shared ancestry and evolutionary pathways. One of the primary aims of Physical Anthropology is to study human evolution. By examining fossil records, skeletal remains, and archaeological findings, physical anthropologists reconstruct the history of human development, tracing the gradual changes in anatomy and physiology from early hominins to modern Homo sapiens. This includes the study of cranial features, dentition, postcranial skeletons, and other anatomical structures that reveal information about locomotion, diet, and environmental adaptations. Through these studies, researchers can understand the adaptive strategies that enabled humans to survive in different ecological contexts and the selective pressures that shaped human evolution. Another important aim is the study of human variation and adaptation. Humans display considerable diversity in physical traits such as skin color, body proportions, facial features, and genetic makeup. Physical anthropologists seek to explain this variation in terms of evolutionary biology, genetics, environmental influences, and health-related factors. For example, variations in skin pigmentation are understood as adaptations to differing levels of ultraviolet radiation, while variations in body size and shape are often linked to climatic conditions. The study of human adaptation also includes the investigation of physiological responses to high altitude, temperature extremes, and nutritional stresses, which reveal the interplay between biology and environment in shaping human survival and health. Physical Anthropology also aims to investigate the genetic and hereditary factors underlying human characteristics. Modern techniques, such as molecular genetics and DNA analysis, allow anthropologists to study population genetics, gene flow, and the evolutionary relationships
