Study suggests dodo may have been more intelligent than previously thought.

An international study, published in the Zoological Journal of the Linnean Society, challenges the long-held belief that the Mauritian dodo was unintelligent. Analysis of its skull anatomy indicates a forebrain proportionally similar to other pigeons, suggesting comparable cognitive abilities. Researchers propose the dodo's lack of fear towards humans stemmed from its isolated habitat without natural predators, not a lack of intelligence.
