For centuries, the dodo has carried the weight of a myth it never deserved — that docility in the face of human arrival was evidence of dim-wittedness rather than a creature simply shaped by a world without predators. Now, researchers scanning the last intact dodo skulls have found not a failed mind but a reorganized one, tuned to low light, deep sound, and sensitive touch in ways that made perfect sense on Mauritius before humanity arrived. The bird was not slow to understand danger; it had evolved in a place where danger, until that moment, did not exist.
