how fast did dodos become extinct? Here we use a statistical method to establish the actual extinction time of the dodo as 1690, almost 30 years after its most recent sighting. Its last confirmed sighting was in 1662, although an escaped slave claimed to have seen the bird as recently as 1674.
Why did the dodo become extinct so quickly? The birds had no natural predators, so they were unafraid of humans.
