The scientists can now (50) surely assume that the dodo developed its distinctive appearance and features as a result of its geographical isolation.

Các nhà nghiên cứu ở trường đại học đã lấy mẫu từ một mẫu chim dodo được bảo tồn trong một nỗ lực để phát hiện ra cây gia phả của loài chim tuyệt chủng. Họ đã làm việc với Bảo tàng Lịch sử Tự nhiên Anh để thu thập và nghiên cứu vật liệu di truyền từ một số lượng lớn mẫu vật: một con chim dodo được bảo tồn, chim solitaire tuyệt chủng và 35 loại chim bồ câu và chim bồ câu trắng sống. Phân tích của họ cho thấy doo và solitaire là họ hàng gần với chim bồ câu Nicobar, họ hàng gần nhất còn sống của chúng. Chim dodo sống trên Mauritius ở Ấn Độ Dương. Đó là một con chim không biết bay, lớn hơn một con gà tây. Đến năm 1681, tất cả các con dodo đã bị giết bởi các thủy thủ đói. Chim solitaire, mà trông giống như một dodo, cũng chết như thế năm 1800. Bằng cách trích xuất đoạn ngắn DNA của dodo và so sánh chúng với DNA của chim sống, các nhà khoa học đã có thể suy ra khi dodo tiến hóa từ họ hàng của nó thành một thực thể riêng biệt. Các nhà khoa học bây giờ có thể chắc chắn cho rằng dodo phát triển bề ngoài và các đặc điểm riêng biệt của nó là do sự cô lập địa lý của nó. Bây giờ họ bị thuyết phục rằng nó tách ra khỏi loài chim solitaire khoảng 25 triệu năm trước, lâu trước khi Mauritius trở thành một hòn đảo.
