New Genetic Study Finds Late Neanderthals Were Not Highly Inbred
A new study analyzing ancient DNA from 27 Neanderthal individuals suggests that the last surviving Neanderthal populations in northwestern Europe were not heavily affected by inbreeding, challenging long-standing theories about their extinction. The research, led by evolutionary anthropologist Alba Bossoms Mesa and colleagues from the Max Planck Institute for Evolutionary Anthropology, reexamined genetic remains from sites in Belgium and France dating to less than 52,500 years ago. Some of these specimens, including Engis 2—the first Neanderthal ever discovered—have been in museum collections for decades or even centuries, with several only recently correctly identified as Neanderthals through modern analysis.
The team’s high-resolution genomic study found no clear evidence of increasing genetic load or decreasing genetic diversity over time. Instead, the data suggests that late Neanderthals in this region were part of a connected and genetically diverse population with relatively low levels of inbreeding. This contrasts with earlier studies based largely on Neanderthal genomes from eastern Eurasia, such as those from Chagyrskaya and Denisova Caves, which showed higher levels of inbreeding and isolation. The new findings indicate that geographic variation played a major role in shaping Neanderthal genetic health and that some populations remained well-connected across large regions.
Researchers also highlight that Neanderthal extinction may not have been driven primarily by genetic deterioration, as previously thought. Instead, environmental pressures, demographic shifts, and interactions with modern humans likely played more complex roles. Evidence continues to support interbreeding between Homo sapiens and Neanderthals, though the study notes that gene flow appears to have been mostly from Neanderthals into modern humans, with no clear evidence of recent modern human ancestry in Neanderthal genomes. The findings add nuance to the debate over Neanderthal extinction, suggesting a more interconnected and regionally varied population history than previously understood.

Neanderthals in Western Europe were doing well right before they went extinct
Neanderthals died out around 40,000 years ago, possibly due to climate change and competition and interbreeding with modern humans, but no one knows for sure. New research on one Neanderthal population in Belgium right before extinction shows that it had healthy levels of genetic diversity and no signs of stress from interbreeding with modern humans. The findings suggest that extinction played out differently across the vast range that Neanderthals occupied across Europe and Central Asia.

5,500 years ago, plague was already killing children in Siberian hunter-gatherer families, no fleas, no cities, no farming required. Ancient DNA reveals a toxin that may explain why kids died and adults didn’t.
