Biological anthropologists seek to understand how humans adapt to diverse environments, and how biological and cultural processes work together to shape growth, development and behavior. They are interested in human biological origins, evolution and variation. Biological anthropologists study other primates (primatology), the fossil record (paleoanthropology), prehistoric people (bioarchaeology), and the biology (e.g., health, cognition, hormones, growth and development) and genetics of living populations.
