EVOLUTION:
Genomic Databases and the Tree of Life
Keith A. Crandall and Jennifer E. Buhay
Even though we are far from finished counting the total number of species on Earth, biologists are eagerly assembling and reassembling the Tree of Life. In their Perspective, Crandall and Buhay discuss an intriguing computational method for assembling a phylogenetic supertree from gene sequences mined from existing genetic databases (Driskell et al.).
