"To tentatively entertain these proposals with anything approaching genuine interest, one would have to believe that ornithological systematists know nothing about phylogenetic relationships." -Anonymous Reviewer of Fain and Houde 2004 Parallel Radiations in the Primary Clades of Birds
My interests lie in the very broad areas of the evolutionary biology of birds, and of mammals to a lesser degree. My research covers several areas. 1) Phylogeny reconstruction - the genealogical relationships of organisms to one another. I am most interested in 'higher-level' interfamilial and interordinal relationships. My lab discovered molecular genetic evidence that at least five traditionally recognized orders of birds are polyphyletic, and mistaken to be related on the basis of convergent morphologies. 2) Biogeography - the correlation of patterns of phyletic divergence and the origins of new taxa to the geographic distribution of species and the formation of geophysical barriers through time. Some researchers conjecture that groups of birds with modern endemism to southern continents must have originated there during the Cretaceous when those continents were united. However, among the orders of fossil birds I have described are the sister group to modern ratites, Lithornithiformes, and a primitive ostrich, Palaeotis, whose Northern Hemisphere distributions are quite inconsistent with those of their modern southern relatives. Similarly, our molecular genetic data show that various "gruiform" birds with southern disjunct endemism (e.g., kagu-sunbittern, or the pantropical finfoot family) are too closely related to have diverged in the Cretaceous. Indeed, fossils suggest that these dispersed through the Northern Hemisphere during the Cenozoic, instead. 3) Macroevolution - the plasticity and polarity of morphological evolution within lineages. This is best understood by exploring pattern in the distribution of morphological characters that are superimposed onto a phylogenetic "tree" inferred independently from molecular genetic analysis. I address these diverse problems through the combined study of fossil vertebrates, comparative anatomy (particularly osteology) and DNA sequencing.
I have separate laboratory facilities devoted to molecular and paleontological studies. In 2009 my lab acquired a "NextGen" DNA sequencer, the 454 - FLX+ along with supporting apparati and staff, as the cornerstone of a new Genome Sequencing Facility at NMSU. Among our department's natural history museums are comparative vertebrate collections for use in research and education.
I welcome inquiries from prospective graduate students who are interested in integrating diverse classical and modern disciplines to address the systematics and macroevolution of any taxonomic group of organisms.
