Avian tree of life

My  research focuses on the evolutionary relationships of modern birds, the most diverse morphological and ecological vertebrate group and the subject of numerous biological studies.  The diversification of birds is postulated to have occurred very rapidly, with the modern orders originating at roughly similar times.  This pattern of radiation has led to enormous difficulty deciphering deep avian relationships.  In fact, higher-level (i.e. interordinal) avian relationships are hotly contested and remained largely unresolved until now, despite numerous studies. Funded by the National Science Foundation’s Assembling the Tree of Life program, the Early Bird project was designed to collect genomic-scale data in order to decipher the phylogenetic relationships of all major lineages of living birds.  This “phylogenomic” study is a collaboration involving five research labs.  Together we collected over 32 kilobases of DNA sequences each for over 200 representatives across the diversity of birds.   More...
