The oldest human ancestors in Western Europe found: Fossilized face fragments.

In a cave in northern Spain, researchers found fossilized face fragments of ancient human ancestors.

The ruins, known as “Pink,” are estimated to be between 1.1 million and 1.4 million years old. However, they pose a mystery as the face fragments do not match any known species from the same area and cannot be definitively identified.

Maria Martinon Torres, a paleontologist at the Spanish National Centre for the Evolution of Humans and a co-author of the study, stated in a press call, “We have documented a previously unknown population in Europe. These fossils represent the earliest human fossils ever discovered in Western Europe.”

The initial fragment was unearthed in 2022, with new details featured in Wednesday’s issue of Nature Journal Nature.

Research findings tentatively suggest that Pink may be linked to human ancestors, potentially Homo Erectus. The fossil was named partly after the band Pink Floyd and Rosa Huguet, the study’s lead author and archaeological site coordinator.

This discovery is significant as it provides a more accurate timeline for the arrival of human ancestors in Western Europe. It also helps bridge the evolutionary gap between the oldest human fossil finds in Europe, dating back about 1.8 million years to the site in dmanisi, Georgia, where Homo Aristroux was discovered, going back approximately 900,000 years.

Rodrigo Lacruz, a professor of molecular pathology at New York University, stated that this finding could aid in understanding early human evolution and migration narratives in Europe.

The research team confirmed that Pink’s fossils are adult but could not determine their gender. The discovery was made about 60 feet deep within the Sierra de Atapueca archaeological site, known for its rich historical record of rock formations.

Within the same sediment layer as Pink, evidence suggests that these early ancestors were involved in hunting and butchering animals for meat.

There is evidence suggesting that human ancestors entered Europe in multiple waves, with many of these groups later diminishing. Fossil records show discontinuity across Atapuerca sites and Western Europe, indicating a prolonged period without human presence.

The study speculates that the species to which Pink belonged may have overlapped temporarily with Homo Alivisor and could have been extinct due to climate changes around 1.1 million years ago.

Chris Stringer, a professor and research leader in human evolution at the Museum of Natural History in London, suggested that a climate event may have caused a significant decline or complete depopulation of humans in Western Europe.

The Simadel Elephante cave, where Pink was discovered, has previously yielded intriguing fossils. In 2007, researchers found a small jawbone believed to be around 1.2 million years old, possibly closely related to Pink.

Maria Martinón-Torres expressed surprise and excitement at the discovery of new fossils even deeper within the cave.

The abundant collection of fossils in the region is likely due to its geographical features, providing a natural corridor and resources that attracted early humans.

Archaeological excavation work in the area is ongoing, with researchers hopeful for more surprises.

“We will continue to excavate,” Martinón Torres stated. “There may be more surprises to come.”
