New research challenges beliefs about Neandertal noses and cold adaptation. The scientists analysed a rare skull revealing unexpected nasal anatomy details. Findings overturn theories linking big noses to icy environments globally.
What did Researchers find?
The researchers discovered Neandertal noses lacked specialised adaptations for severe cold. Large nasal cavities appeared proportional to robust skulls rather than temperature. Cold-climate features seen in Arctic populations were absent in Neandertal samples. This evidence suggests facial size, not climate, shaped nasal evolution patterns.
Research on Neandertals
Neandertals were ancient humans living across Europe and western Asia. They inhabited cold regions with rugged landscapes and limited resources. Harsh Ice Age climates often influenced their bodies and survival strategies. This research focused on the Altamura skull discovered previously within Italian caves.
How Was the Research Conducted?
Scientists used tiny endoscopic cameras to access internal nasal structures. The method avoided damaging fragile fossil bones preserved within the skull. High-resolution imaging produced detailed reconstructions for comparative anatomical studies. Digital models allowed scientists to analyse nasal shapes with precision.
Key Observations and Future Research
Researchers observed internal patterns similar to modern human nasal architecture. These findings suggest airflow in Neandertals mirrored contemporary human patterns. Scientists emphasise increased sampling is essential for confirming broader evolutionary trends.
Future studies will use simulations to model airflow across ancient faces. Additional fossils may reveal diversity hidden within Neandertal populations previously assumed uniform.
