Did you know that scientists have 3D-printed Lucy’s bones to study how she died? Did you know her injuries match those seen in modern humans who fall from tall heights?

In this video, we investigate the latest theory on the death of Lucy, the 3.2-million-year-old fossil of Australopithecus afarensis who changed everything we know about human evolution. A groundbreaking study from the University of Texas at Austin suggests that Lucy may have died from a fall out of a tall tree. Using high-resolution CT scans and forensic reconstruction, researchers found fracture patterns across her skeleton—particularly in her arms, ribs, and legs—that mirror those seen in real-life fall victims.
But not everyone is convinced. While some scientists argue these injuries occurred near the time of death, others claim they’re simply the result of fossilization over millions of years. This controversy cuts to the core of debates about whether Lucy lived mostly in the trees or on the ground. Was she a climber who fell victim to evolutionary trade-offs—or are we reading too much into broken bones?
We also explore the incredible new efforts to democratize science, including the public release of Lucy’s 3D bone files. For the first time, students, teachers, and curious minds can print and examine part of Lucy’s skeleton themselves. It’s a milestone in open-access science and a tribute to the lasting impact of the most famous fossil in the world.
Lucy’s story doesn’t just end with how she died—it continues to evolve as new technology and bold ideas bring us closer to understanding the lives of our earliest ancestors.
