What if care is the oldest root of being human? Thirty-one thousand years ago, in a cave in the mountains of Borneo, a community performed the oldest known successful major operation and nursed a child back to life over the decade that followed. This is where compassion begins.

In developmentExhibitionIn 2020, during Dr. Maxime Aubert's long search for the world's oldest cave art, his postdoc, the late Dr. Tim Maloney, made the discovery, co-leading the dig with Dr. India Dilkes-Hall. Their patient work in the cave floor turned up what no one was looking for: a careful, deliberate burial in a remote cave we now call Liang Tebo.
The skeleton was a young person, around 14 when injured, whose lower-left leg had been surgically amputated and fully healed. The smooth, infection-free bone is the mark of skilled surgery. That it kept growing for years afterward tells us a community carried and cared for the child long after. Published in Nature, it is the oldest known successful major operation in human history.
And it does not stand alone. Around the burial, the cave walls hold some of the world's oldest hand stencils, and ochre was found in Tebo 1's own mouth, linking the grave to art and ritual. A single cave holding evidence of surgery, art, and burial marks a turning point in the human story.
Surviving a childhood amputation and living into adulthood took more than a skilled hand. It took a community that chose to stay, and to carry one of its own for years.
Tebo 1's story rises from a land of firsts, where some of the oldest art on Earth still glows on cave walls. Against the cold logic of survival of the fittest, here is a life that an entire community chose to hold up.
Together, the healed bone and the hand stencils nearby say something simple. Our humanity was born of a choice to care for one another. This is the genesis of compassion.
At the heart of it is a child who lived 31,000 years ago. And for the people rediscovering and telling their story, the care that kept Tebo 1 alive is not an idea to be argued. They have lived it, from both sides.
An archaeologist and geochemist at Griffith University, Maxime is a leading authority on dating the deep past. His uranium-series dating of cave art established the age of the oldest figurative paintings ever found, moving the origins of art from Europe to the islands of Southeast Asia. His search for humanity's earliest images first brought the team to Liang Tebo. He grew up beside the same truth Tebo 1 carries: his father lost a leg at twelve, and care for an amputee was part of his own childhood.
Imagined reconstruction.
The child at the heart of it all. A leg lost below the knee in childhood, and bone that kept growing for ten years afterward, proof that a community carried and cared for Tebo 1 long after the surgery. Ochre in the mouth and stained teeth may be among the earliest traces of plant medicine. Newer DNA analysis hints at an endocrine difference, a body that may have been intersex. The oldest proof we have that to be human is to care. Every part of this work exists to carry that story forward.
An engineer turned National Geographic Explorer, storyteller, and below-knee amputee, Albert has built his career revealing lost worlds without disturbing them — using LiDAR to lift hidden histories from the dark, from the Maya cities to the Holy Lands, in series like Lost Cities with Albert Lin. The same tools now bring Tebo 1's cave to light. He carries Tebo 1's exact loss, and has known care from the other side: when his young son's life hung by a thread, family carried him back — his own handprints on the cave wall.
"My own community became my hand stencils on the cave wall."

"The story of Tebo 1's world is written on the walls of these caves, and there is so much yet to be found."
Dr. Maxime AubertWho dated the world's oldest known rock art
This November's expedition has three goals, pursued as one: to capture Liang Tebo in ultra-photorealistic LiDAR before it is lost, to film the documentary that launches Tebo 1's story, and to push into the unexplored high karst of Tondoyan in search of caves and rock art no one has yet recorded. The full logistics are in the timeline below.
From the river head, two days by canoe carry the team and its gear deep into the Sangkulirang–Mangkalihat karst to Liang Tebo, far beyond any road or signal. This is the isolation that has kept the story untouched for 31,000 years.
Five days at the discovery site. Terrestrial LiDAR and photogrammetry build a millimetre-accurate 3D archive of Liang Tebo, while drone-LiDAR survey grids strip the canopy off the surrounding karst to guide on-foot recon of new cave systems no one has entered.
A two-to-three-day river portage pushes deeper into the landscape to Tondoyan, the highest karst formation in the region and one of its least explored.
Two weeks exploring the vast cave systems of Tondoyan, dark mouths visible from across the valley but never entered, searching for the new rock art and burial chambers that could carry Tebo 1's story across the wider karst.
The team runs the river back out, carrying redundant copies of the data the whole way. What leaves is a permanent spatial archive of two of the world's most significant prehistoric landscapes, the foundation for film and for the case for UNESCO World Heritage protection.
Conducted with BRIN and the Dayak custodian communities, and screened in-region first. Indicative field plan; exact dates and durations depend on river conditions, weather, and permits. Imagery is AI-generated concept art for TEBO 1.
A single LiDAR scan serves both halves of this project. It searches the karst for caves no one has found, and it records Liang Tebo in photoreal 3D so the rest of the world can step inside.

Drag the drone. Aerial LiDAR sees through the canopy to the bare limestone, revealing cave openings no one has entered. Highlighted: potential cave openings. Concept visualization.
From that LiDAR data, Visualskies reconstructs Liang Tebo and its 31,000-year-old world in photoreal 3D, the foundation for the documentary and the immersive experiences that carry it to everyone.
The same LiDAR and 3D toolkit behind Lost Cities with Albert Lin, refined over fifteen years with Visualskies and now turned on Liang Tebo.
Tebo 1’s world, the Sangkulirang–Mangkalihat karst of East Kalimantan, is being eaten away by logging, mining, and palm-oil monocropping. Without action, the cave, its burial, and the ancient art our species left there could be lost within years.
Tebo 1’s home holds more ancient rock art than anywhere else in Southeast Asia, including some of the oldest figurative paintings ever found on Earth, dated in these very caves by our own Dr. Maxime Aubert. It is also counted among the ten most endangered karst landscapes in the world.
Its limestone is hunted for cement, its forest cleared for oil-palm, coal, and logging, with pressure rising as Indonesia builds its new capital, Nusantara, nearby. More than 40% of the karst here already sits under mining concession. Quarry a single tower and the caves, burials, and art inside are gone for good.
Nothing here is done to the region; it is done with it. The work is co-designed with BRIN, Indonesia’s National Research and Innovation Agency, Indonesian scholars, and the Dayak custodian communities whose ancestral land this is, with consent first and screenings in the region before anywhere else.
So the vision works on two fronts. The first: carry this story of care to the world when it is badly needed, hard proof, written in bone and ochre, that our origins are good, and a spark for new stories of what we can be to one another. The second: turn that attention back onto the karst, so the spotlight becomes a shield, strengthening the case for UNESCO World Heritage protection and backing the Indigenous and local stewardship already fighting to hold this landscape against mining, logging, and monocropping.

This November's expedition is step one. From it we create a 25-minute documentary and an immersive VR experience. From there the full ambition follows: a feature film, a traveling exhibition, and a conservation initiative, each retelling human origins as a story of care.
