Caught between modernity and 20,000 years as hunter-gatherers, the San people sit at a crossroads.
An indigenous people in Southern Africa, they are our oldest human ancestors, DNA testing proving the San are direct descendants of the first Homo sapiens. But today their culture, traditions and heritage are at risk of being lost forever.
The San live across South Africa, Botswana, Angola and Namibia. In Botswana they're known as the Basarwa, where they live a largely nomadic lifestyle that has remained undisturbed for millennia.
"Culture is something that can die and we should understand that culture is dynamic," says Bihela Sekere, part of the indigenous population who previously worked at the Botswana High Commission in London.
Sekere grew up in the Central Kalahari Game Reserve, the second largest of its kind in the world, hunting as his father had done before him. But in 1997 the government began removing the Basarwa from the reserve, ostensibly to protect the area and integrate the community into mainstream society.
Now based in a resettlement village, passing on age-old traditions has become harder and harder for the Basarwa.
"Some of the kids, Basarwa kids, are taken to schools (and) they can lose their culture because they are taught other ways of living," explains Sekere. "To start with the language — if they are taught Setswana and English, it means the language will suffer."
Sekere also cites the famous trance dance, a stalwart of Basarwa culture, as something that could one day suffer at the hands of modern music, played on radios and mobile phones by youths.
Hope is not lost, however, while there are those willing to preserve indigenous culture. Local man Xontae guides the curious around some of his people's greatest heritage sites, including the Tsodilo Hills, where 4,500 rock paintings dating back to the Stone Age can be explored. Meanwhile the Kuru Art Project seeks to revive art making among the Basarwa once more.
