They worked with the British Natural History Museum to collect and study genetic material from large number of specimens: a preserved dodo, the extinct solitaire bird, and 35 kind of living pigeons and doves. Their analysis (2)  the doo and the solitaire to  be  close  relatives with the Nicobar pigeon, their nearest living relative. The dodo lived on  Mauritius in the  Indian Ocean. It was a flightless bird, bigger than turkey. By 1681, all dodos had been (3)    by    hungry sailors. The solitaire, which looked a bit like a dodo, had gone the same way by 1800. By extracting short pieces of the dodo's DNA and  (4) these with the DNA of living birds, the scientists were able to deduce when the dodo evolved away from its relatives into a separate entity.    The scientists can now (5)      assume that the dodo developed its distinctive appearance and features as a result of its geographical isolation. They are now convinced that it separated from the solitaire about 25 million years ago, long before Mauritius became an island.
