The Society for Anthropological Sciences (SAS) was organised to promote empirical research and social science in anthropology. The members of SAS want to further the development of anthropological science as empirical knowledge based on testable theory, sound research design and systematic methods for the collection and analysis of data. We seek to fulfill the historic mission of anthropology to describe and explain the range of variation in human biology, society, and culture across time and space.

The stated objective of the SASci is to advance the scientific study of human societies through scholarly meetings, publications, and related activities. The SASci also advances the dissemination of anthropological knowledge within the scientific community, to other educators, and to the broader general public. The SASci encourages active student participation and facilitates student incorporation into the professional research community.

Within the AAA, the Society for Anthropological Sciences is a section. The acronym for this group is SAS. SASci also incorporated as an independent, non-profit, scholarly and educational association. Non members of the AAA belong the latter organization only. AAA members have dual membership.
