TEBO 1 · The Genesis of Compassion

TEBO 1

The Genesis of Compassion

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.

The Discovery

A skeleton that rewrote the human story.

In 2020, during a long search for the world's oldest cave art led by Dr. Maxime Aubert, the discovery itself was made by his student, the late Tom Maloney. His patient work in the cave floor turned up something 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 at the time of injury, whose lower-left leg had been surgically amputated and then 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 medical 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, which links the grave to art and ritual. A single cave holding evidence of surgery, art, and burial marks a turning point in the human story.

Care, not conquest, may be the oldest human trait.

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.

A Personal Connection

Why this story feels personal.

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 one of the world's foremost authorities on dating the deep past. By pioneering uranium-series dating of cave art, he established the age of the oldest figurative paintings ever found, work that moved the origins of art out of Europe and into the islands of Southeast Asia. It was his long search for humanity's earliest images that first brought the team to Liang Tebo. And he grew up beside the same truth Tebo 1 carries: a father who lost a leg at twelve. For him, this science was never only academic.

Tebo 1

Project Lead · 31,000 Years Ago

The child at the heart of it all. A leg lost below the knee in childhood, 31,000 years ago, and bone that kept growing for ten more years afterward, proof that Tebo 1 was carried and cared for by a community long after the surgery. Ochre in the mouth and staining across the teeth may be among the earliest traces of plant medicine ever found. Newer DNA analysis hints at an endocrine difference, and a body that may have been intersex: a person who did not fit the mold. 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 and remote sensing to lift hidden histories from the dark, from the Maya cities beneath the jungle to the Holy Lands, across 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, a leg below the knee, in 2016, and has known care from the other side: when his young son Charlie's life hung by a thread, family and caregivers carried him back. For Albert, the handprints around Tebo 1 are his own community on the cave wall, the genesis of compassion.

"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."
Upcoming Expedition

November 2026

Sangkulirang–Mangkalihat Karst · East Kalimantan, Borneo · ~1°N 118°E

A roughly four-week field season, run as one integrated operation with science and storytelling moving together from the first river mile to the last scan. Staged out of Balikpapan, the team drives to the river head, travels two days by canoe to Liang Tebo, then portages deeper into the landscape to the unexplored high karst of Tondoyan, carrying everything it needs to stay self-sufficient far beyond roads or rescue.

The Expedition Plan
1
Phase 01 · Days 1–2 · Canoe in

Two days upriver to Liang Tebo

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.

Phase 02 · Days 3–7 · Liang Tebo

Scan the site, search the karst

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.

Phase 03 · Days 8–10 · Portage

River portage to Tondoyan

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.

Phase 04 · Days 11–24 · Tondoyan

Into the unexplored

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.

Phase 05 · Days 25–27 · Out & deliver

Carry it to the world

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.

The Technology · LiDAR & Visualskies

One scan, two missions.

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.

A Race Against Time

The caves that hold this story are vanishing.

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.

Conservation · Co-Stewardship

Awareness may be the karst’s best protection.

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 monocropping, coal, and logging, with pressure now intensifying as Indonesia builds its new capital, Nusantara, nearby. More than 40% of the karst across this part of Borneo already sits under mining concession. Quarry a single tower and the caves, the burials, and the art inside them 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, with Indonesian scholars, and with 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 is to carry this story of care to the world at a moment 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 is to turn that global attention back onto the karst itself, 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.

The Vision

Lifting the most powerful and iconic human story never told.

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

The Launch Pad

Supported by the November expedition — with anticipated support from the National Geographic Society, currently in review.
