A study of the inner ear bones of Neanderthals shows a significant loss of diversity in their shape around 110,000 years ago, suggesting a genetic bottleneck that contributed to Neanderthals' decline.

Neanderthal genetic diversity dropped 110,000 years ago CT scans of inner ear bones show a major bottleneck event Reduced diversity may have weakened their survival chances ...

New research on the inner ear morphology of Neanderthals and their ancestors challenges the widely accepted theory that Neanderthals originated after an evolutionary event that implied the loss of ...

As brain states changed, cochlear activity stayed the same, suggesting that the inner ear does not modulate hearing on a short-term basis. Next, the researchers genetically altered mice to disable ...
