  Anthropology is a global discipline involving humanities, social sciences and natural sciences. Anthropology builds upon knowledge from natural sciences, including the discoveries about the origin and evolution of Homo sapiens, human physical traits, human behavior, the variations among different groups of humans, how the evolutionary past of Homo sapiens has influenced its social organization and culture, and from social sciences, including the organization of human social and cultural relations, institutions, social conflicts, etc. Early anthropology originated in Classical Greece and Persia and studied and tried to understand observable cultural diversity, such as by Al-Biruni of the Islamic Golden Age. As such, anthropology has been central in the development of several new (late 20th century) interdisciplinary fields such as cognitive science, global studies, and various ethnic studies.
  
  According to Clifford Geertz,
  
  ...anthropology is perhaps the last of the great nineteenth-century conglomerate disciplines still for the most part organizationally intact. Long after natural history, moral philosophy, philology, and political economy have dissolved into their specialized successors, it has remained a diffuse assemblage of ethnology, human biology, comparative linguistics, and prehistory, held together mainly by the vested interests, sunk costs, and administrative habits of academia, and by a romantic image of comprehensive scholarship.
  
  Sociocultural anthropology has been heavily influenced by structuralist and postmodern theories, as well as a shift toward the analysis of modern societies. During the 1970s and 1990s, there was an epistemological shift away from the positivist traditions that had largely informed the discipline. During this shift, enduring questions about the nature and production of knowledge came to occupy a central place in cultural and social anthropology. In contrast, archaeology and biological anthropology remained largely positivist. Due to this difference in epistemology, the four sub-fields of anthropology have lacked cohesion over the last several decades.
