Dodo genetics

The dodo (originally Didus ineptus and renamed Raphus cucullatus) is a mysterious, now extinct, bird that has been difficult to position in evolutionary trees.

The dodo (originally Didus ineptus and renamed Raphus cucullatus) is a mysterious, now extinct, bird that has been difficult to position in evolutionary trees. In the March 1 Science, Beth Shapiro and colleagues at the University of Oxford, UK, report a genetic analysis of the evolutionary history of the dodo (Science 2002, 295:1683).

Shapiro et al. examined DNA sequences amplified from the mitochondrial genomes of 37 species of pigeons and doves, including the dodo and the another flightless bird called the solitaire. They used the data to construct a phylogenetic tree and concluded that the dodo and the solitaire are indeed sister taxa, nested with pigeons within the family Columbidae. Using external fossil calibrations, they were able to estimate that the dodo and the solitaire separated about 25.6 million years ago.
