Biological Anthropology

Biological anthropology is the academic study of human genetics, behavior, and adaptation. It is a discipline of anthropology that focuses on the biological and physiological composition of individuals, as well as their genetic make-up and behavioral adaptations. This field of inquiry is also sometimes referred to as physical anthropology. The fundamental purpose of biological anthropologists is to understand biological and genetic differences within and among human groups, as well as how these variations have developed over time as a consequence of natural selection and other causes. They also explore the influence of cultural and environmental elements on human biology and health.

Subfields of Biological Anthropology

Biological anthropology, commonly known as physical anthropology, is the study of human biology and behavior in relation to evolution, genetics, and ecology. The purpose of this discipline of anthropology is to grasp the biological basis of human variety and adaptation over time and place, from the earliest hominins to current humans. Biological anthropologists apply a variety of scientific methods, including genetics, anatomy, and ecology, to examine problems relevant to human evolution, behavior, and health. Each of the minor subfields within the greater discipline has its own study topics, methodology, and areas of specialization.

Branches of Biological AnthropologyDescription
PaleoanthropologyThe study of human evolution through the examination of fossils, archaeological remains, and other evidence from past human populations.
PrimatologyThe study of non-human primates, including their behavior, social organization, genetics, and anatomy, in order to gain insights into human evolution, behavior, and biology.
Human BiologyThe study of the biological variation within and between human populations, including genetics, physiology, and anatomy.
Forensic AnthropologyThe application of biological and anthropological methods to the investigation of crimes and legal cases, including the identification of human remains, determining causes of death, and establishing the biological profile of individuals.
Biocultural AnthropologyThe study of the interactions between biology and culture, including the ways in which cultural practices and environmental factors influence human biology and health.
Human Behavioral EcologyThe study of the evolution of human behavior, including the ways in which behavior is influenced by environmental and ecological factors.
Medical AnthropologyThe study of the ways in which culture and society influence health, illness, and healing practices, as well as the ways in which biological and genetic factors interact with cultural practices and beliefs to shape health outcomes

Origins of Biological Anthropology

The origins of biological anthropology can be traced back to the 19th century, with the emergence of the field of physical anthropology. Early physical anthropologists focused primarily on the measurement and classification of human skulls and bones, using these data to make inferences about the physical characteristics of different human populations. This approach, known as craniometry, was popularized by scholars such as Paul Broca and Franz Boas.

However, over time, physical anthropology expanded to encompass a broader range of topics, including human evolution, genetics, and ecology. The field was influenced by the discoveries of Darwin and Wallace, who proposed the theory of evolution by natural selection in the mid-19th century. This theory provided a framework for understanding the biological origins of humans and their relationship to other primates.

In the early 20th century, biological anthropology became more interdisciplinary, incorporating insights from genetics, anatomy, and physiology. With the advent of molecular biology in the mid-20th century, the field began to incorporate molecular genetics and genomics into its research programs. Today, biological anthropology continues to evolve, with new technologies and methods enabling researchers to explore questions related to human biology and behavior in increasingly sophisticated ways.

“New Physical Anthropology”

“New Physical Anthropology” is not a term commonly used within the field. However, there have been several significant developments and changes within physical anthropology over the years that could be considered as “new” or innovative. Some examples include:

  • The use of genetic and molecular approaches in studying human evolution and population genetics.
  • The application of bioarchaeology, which combines techniques from physical anthropology, archaeology, and history to understand past populations and their lifestyles.
  • The integration of biocultural perspectives, which recognizes the interaction between biology and culture in shaping human diversity and adaptation.
  • The adoption of new technologies and imaging techniques, such as computed tomography (CT) scanning and 3D printing, to study skeletal remains and anatomical structures.

These are just a few examples of how physical anthropology has evolved and adapted over time to incorporate new methods, technologies, and perspectives.

What do Biological Anthropolgist do?

Biological anthropologists study the biological and behavioral aspects of human beings, both past and present. They examine the physical and genetic traits of humans and their close relatives, such as primates, to better understand human evolution, variation, and adaptation. Some specific tasks of biological anthropologists include:

  • Conducting fieldwork to collect data on human biology, behavior, and cultural practices.
  • Analyzing genetic data to understand human ancestry and evolution.
  • Examining human skeletal remains to understand patterns of health, disease, and injury in the past.
  • Studying primate behavior to better understand human social behavior.
  • Investigating the impact of environmental factors on human biology and health.

Overall, biological anthropologists use a combination of laboratory research, fieldwork, and data analysis to gain a better understanding of human biology and evolution.
