The Khoisan are the indigenous peoples of southern Africa, widely recognized as one of the oldest human populations on Earth. The term combines two distinct groups: the Khoekhoe (historically pastoralists who herded livestock) and the San (hunter-gatherers). Genetic evidence places the split between the Khoisan lineage and other modern human populations at roughly 90,000 years ago, making them carriers of some of the deepest-rooting branches in the human family tree.
Two Peoples Under One Name
Though “Khoisan” is used as a single label, it actually describes two culturally distinct groups who have lived across what is now South Africa, Namibia, Botswana, Angola, and neighboring countries for tens of thousands of years.
The San were the earliest hunter-gatherers in southern Africa. They lived in caves, hunted game, foraged for wild plants, and organized themselves around an appointed clan leader. San society was deeply egalitarian: everyone hunted, everyone gathered, and food was shared among the group. No one was considered wealthier than anyone else.
The Khoekhoe, by contrast, were pastoralists. They kept sheep and cattle, lived in camps, and measured wealth by the number of animals a person owned. Animals were a visible status symbol, and Khoekhoe people sometimes smeared animal fat on their bodies as a display of prosperity. Their society had clear economic stratification, with richer and poorer members. Unlike the San, the Khoekhoe did not appoint a single leader but organized themselves more loosely. Despite these differences, the two groups shared the same broad region and had enough cultural overlap that outsiders often grouped them together.
The Oldest Genetic Lineage
Modern genetics has confirmed what archaeologists long suspected: the Khoisan descend from one of the earliest branches of the human species. Research published in the American Journal of Human Genetics examined 500 mitochondrial DNA sequences from lineages found primarily in southern African populations. Two haplogroups, known as L0d and L0k, represent some of the deepest-rooting maternal lineages in all of modern humanity. The split between these two lineages dates to approximately 145,000 years ago, with a confidence interval of 118,000 to 179,000 years.
The broader split between the Khoisan lineage and other modern humans has been dated to no later than 90,000 years ago. To put that in perspective, anatomically modern humans only left Africa in large numbers around 60,000 to 70,000 years ago. The Khoisan genetic line was already distinct long before that migration began. This makes living Khoisan communities a direct, continuous link to some of the earliest chapters of human history.
Click Languages
Khoisan languages are famous for their click consonants, sounds that exist in very few other language families worldwide. A click is produced by trapping air between two points of contact in the mouth and then releasing the front closure to create a sharp burst of sound. Different click types are made by changing where the front closure sits: behind the teeth, on the roof of the mouth, or on the side of the tongue.
The Khoisan language cluster includes multiple distinct families, among them the Khoekhoe and Tuu families. Languages in the Tuu family tend to have the largest inventories of click sounds, with more variations and accompaniments than other Khoisan languages. Some varieties include rare combinations, such as clicks that produce two distinct noise bursts, one from the front release and a second from a deeper release in the throat. These double-burst clicks are unusual even among click languages. The Khoekhoe languages also feature clicks and are generally described as having a wider vocabulary and more complex sound system compared to the San languages, though both groups use clicks extensively. A few neighboring Bantu languages, including Zulu and Xhosa, borrowed click sounds through centuries of contact with Khoisan speakers.
Rock Art and Cultural Heritage
The Khoisan left behind one of the richest rock art traditions anywhere in the world. Southern Africa contains thousands of sites with both paintings and engravings. Paintings tend to appear in caves and shelters in mountainous areas, while engravings are more common on open rock surfaces in flatter regions like South Africa’s Northern Cape.
The oldest known examples come from the Apollo 11 Shelter in Namibia, where painted stones have been dated to roughly 27,000 years ago. That makes these artworks far older than the famous cave paintings at Lascaux in France (around 17,000 years old). The images include animals, human figures, and scenes often interpreted as depicting spiritual experiences, particularly trance states associated with San healing rituals. Rock art was not merely decorative. It functioned as a visual language tied to the spiritual and social life of the community.
Traditional Plant Knowledge
Living in environments that ranged from the Kalahari Desert to coastal scrublands, the Khoisan developed an extensive knowledge of medicinal plants over millennia. A comprehensive review of Khoi-San and Cape Dutch ethnobotany documented roughly 170 items in the traditional pharmacopoeia, most of them indigenous and endemic plant species found nowhere else on Earth. The collection also included fungi, seaweeds, lichens, and mineral substances.
Two plants in particular have drawn global attention. Hoodia, a succulent traditionally used by San hunters to suppress hunger on long treks, became the subject of international patent disputes when pharmaceutical companies tried to develop it as a weight-loss supplement. Pelargonium, used for respiratory ailments, was similarly commercialized. Both cases raised difficult questions about intellectual property rights and whether indigenous communities should share in the profits from knowledge they developed over centuries.
Modern Challenges and Recognition
Despite their deep roots in southern Africa, Khoisan communities today face significant marginalization. Colonial-era violence, forced removals, and assimilation policies devastated their populations and disrupted traditional ways of life. In South Africa, the democratic transition in 1994 brought new constitutional rights, but practical recognition has been slow.
The Traditional and Khoi-San Leadership Bill was designed to formally recognize Khoisan leaders and communities, but the South African Human Rights Commission found that it placed a much greater burden on Khoisan groups than on other traditional communities. Khoisan applicants were required to submit lists of members with copies of identity documents and individual signatures, a standard not imposed on other groups. Land restitution has been similarly difficult. The Restitution of Land Rights Act allows claims for land taken after 1913, but much of the Khoisan dispossession happened centuries earlier, during Dutch and British colonization, placing it outside the law’s reach.
Healthcare access remains a pressing issue. A study of a Khoisan community of roughly 5,000 people in South Africa’s Northern Cape province found the town had no psychologist, no social worker, and no mental health nurse. Western health systems imposed during the colonial period have often been underfunded and poorly adapted to indigenous communities, and laws like the Witchcraft Suppression Act of 1957, which effectively criminalized aspects of traditional healing, remain on the books in South Africa’s current democratic era. Researchers have called for health systems that integrate indigenous healing practices rather than replacing them, recognizing that Khoisan communities maintain therapeutic traditions, including health dialogues led by elders, that carry real psychosocial value.
Across southern Africa, Khoisan advocacy groups continue pushing for land rights, cultural preservation, and formal political representation. Their situation reflects a broader pattern seen with indigenous peoples worldwide: communities with the longest histories in a region often have the least institutional power within it.
