Evolutionary trees are useful for modeling the evolutionary history of species or genes.
An ultimate goal of biology is to reconstruct the evolutionary history of all known species. The determination of the evolutionary relationship of all green plants alone will involve hundreds of millions of species. Tree reconstructions of such scales require multidisciplinary collaboration as well as enormous computational resources. In this talk, we will briefly describe some ongoing projects at Yale on developing necessary computational technologies, including algorithms and systems. The technical discussion will focus on our recent discovery of an algorithm for reconstructing evolutionary trees from biomolecular sequences.
