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. While we are not certain when, if ever, the necessary data will be ready, DNA sequences of more and more species are becoming available. In this talk, we will discuss a new algorithm for reconstructing evolutionary trees from biomolecular sequences.
