Explore how the Sima de los Huesos in Spain is rewriting human origins with the oldest mitochondrial genome ever recovered from 430,000-year-old human relatives.

The Sima de los Huesos fossils have thrown a massive wrench into the gears of human evolution, revealing that you can't always judge a hominin by its skull—sometimes the genes have a much older and more complex story to tell.
The Oldest Mitochondrial Genome Sequence of a Hominin






The Sima de los Huesos, or "Pit of Bones," is a remarkable archaeological site located deep within the Sierra de Atapuerca in northern Spain. Situated at the base of a thirteen-meter vertical shaft, this site has preserved the remains of at least twenty-eight individuals dating back approximately 430,000 years. Its unique, stable environment has allowed for the recovery of the oldest mitochondrial genome sequence from a human relative, providing a miraculous look into ancient DNA.
The fossils discovered at Sima de los Huesos are actively rewriting the story of human origins by challenging previously established timelines of evolution. These 430,000-year-old remains display a bewildering mix of physical features that complicate the neat narrative of how modern humans and their relatives developed. By analyzing these ancient specimens, researchers are gaining new insights into the complex history and ancestry of the human lineage.
The preservation of ancient DNA and fossils in the Pit of Bones is due to the site's highly stable and protected environment. Located nearly thirty meters below the surface, the cave maintains a constant temperature of 10.6 degrees Celsius and near-saturated humidity. This cold, consistent climate shielded the biological material from the chaos of the surface world for hundreds of thousands of years, making the recovery of a mitochondrial genome sequence possible.
