San people
The San peoples (also Saan), or Bushmen, are the members of any of the indigenous hunter-gatherer cultures of southern Africa, and the oldest surviving cultures of the region.[1] Their recent ancestral territories span Botswana, Namibia, Angola, Zambia, Zimbabwe, Lesotho,[2] and South Africa.

The San speak, or their ancestors spoke, languages of the Khoe, Tuu, and Kxʼa language families, and can be defined as a people only in contrast to neighboring pastoralists such as the Khoekhoe and descendants of more recent waves of immigration such as the Bantu, Europeans, and Asians.
In 2017, Botswana was home to approximately 63,500 San, making it the country with the highest proportion of San people at 2.8%.[3]
Definition[edit]
In Khoekhoegowab, the term "San" has a long vowel and is spelled Sān. It is an exonym meaning "foragers" and is used in a derogatory manner to describe people too poor to have cattle. Based on observation of lifestyle, this term has been applied to speakers of three distinct language families living between the Okavango River in Botswana and Etosha National Park in northwestern Namibia, extending up into southern Angola; central peoples of most of Namibia and Botswana, extending into Zambia and Zimbabwe; and the southern people in the central Kalahari towards the Molopo River, who are the last remnant of the previously extensive indigenous peoples of southern Africa.[4]
Genetics[edit]
Various Y chromosome studies show that the San carry some of the most divergent (earliest branching) human Y-chromosome haplogroups. These haplogroups are specific sub-groups of haplogroups A and B, the two earliest branches on the human Y-chromosome tree.[52][53][54]
Mitochondrial DNA studies also provide evidence that the San carry high frequencies of the earliest haplogroup branches in the human mitochondrial DNA tree. This DNA is inherited only from one's mother. The most divergent (earliest branching) mitochondrial haplogroup, L0d, has been identified at its highest frequencies in the southern African San groups.[52][55][56][57]
In a study published in March 2011, Brenna Henn and colleagues found that the ǂKhomani San, as well as the Sandawe and Hadza peoples of Tanzania, were the most genetically diverse of any living humans studied. This high degree of genetic diversity hints at the origin of anatomically modern humans.[58][59]
A 2008 study suggested that the San may have been isolated from other original ancestral groups for as much as 50,000 to 100,000 years and later rejoined, re-integrating into the rest of the human gene pool.[60]
A DNA study of fully sequenced genomes, published in September 2016, showed that the ancestors of today's San hunter-gatherers began to diverge from other human populations in Africa about 200,000 years ago and were fully isolated by 100,000 years ago.[61]
Hoodia traditional knowledge agreement[edit]
Hoodia gordonii, used by the San, was patented by the South African Council for Scientific and Industrial Research (CSIR) in 1998, for its presumed appetite suppressing quality. A licence was granted to Phytopharm, for development of the active ingredient in the Hoodia plant, p57 (glycoside), to be used as a pharmaceutical drug for dieting. Once this patent was brought to the attention of the San, a benefit-sharing agreement was reached between them and the CSIR in 2003. This would award royalties to the San for the benefits of their indigenous knowledge.[65] During the case, the San people were represented and assisted by the Working Group of Indigenous Minorities in Southern Africa (WIMSA), the South African San Council and the South African San Institute.[24][25]
This benefit-sharing agreement is one of the first to give royalties to the holders of traditional knowledge used for drug sales. The terms of the agreement are contentious, because of their apparent lack of adherence to the Bonn Guidelines on Access to Genetic Resources and Benefit Sharing, as outlined in the Convention on Biological Diversity (CBD).[66] The San have yet to profit from this agreement, as P57 has still not yet been legally developed and marketed.
