What to know about Dodos probably weren't as stupid as historians made them out to be: new research

Researchers used high-resolution CT scans of dodo skulls to analyze brain structure, finding that the bird's cognitive proportions were similar to those of modern pigeons. The study also suggests that the dodo may have been adapted for low-light vision, potentially to avoid competition with giant tortoises.

Why it matters

This famous flightless bird has become a symbol of extinction.

Common ground

Its demise is often portrayed as almost inevitable: a supposedly foolish creature that naïvely approached the sailors who killed it.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
