Ravens are among the birds whose remains are found at Neanderthal sites
Our evolutionary cousins the Neanderthals were harvesting feathers from birds in order to use them as personal ornaments, a study suggests.
The authors say the result provides yet more evidence that Neanderthal thinking ability was similar to our own.
The analysis even suggests they had a preference for dark feathers, which they selected from birds of prey and corvids - such as ravens and rooks.
Details of the research appear in Plos One journal.
