What to know about Scientific Revisionism

Researchers from several international institutions used CT scans of dodo and pigeon skulls to analyze brain size and sensory traits. The study suggests that dodos were not unintelligent and may have been nocturnal, contrary to their historical reputation as 'silly' birds.

What happened

Dodo birds more clever than we thought Gaby Clark Scientific Editor Robert Egan Senior Editor The Mauritian dodo—a global symbol of human-caused extinction and one of the world's largest pigeons—may not have deserved its reputation as a silly simpleton and…

Why it matters

An international study led by Canada's University of Lethbridge Iwaniuk Lab, including Flinders University researchers, has shown that the dodo's brain was not smaller than expected for a bird of its whopping size.

Common ground

The team also found several traits in its skull and brain that are usually found only in birds that are active at dusk or night, according to University of Lethbridge Ph.D.
