All the Birds in the World: One of the most ambitious phylogenetic trees every constructed, this chronicle of avian evolution begins in the time of dinosaurs and ends in 9,993 living bird species, conveying the awesome generative process that is evolution.
'Tree of life' constructed for all living bird species : Scientists have mapped the evolutionary relationships among all 9,993 of the world's known living bird species. The study, published today in Nature1, is an ambitious project that uses DNA-sequence data to create a phylogenetic tree — a branching map of evolutionary relationships among species — that also links global bird speciation rates across space and time.
