The realization that all organisms on Earth are related by common descent was one of the most profound insights in scientific history. The goal of reconstructing the tree of life is one of the most daunting challenges in biology. The scope of the problem is immense: there are 1.8 million named species, and most species have yet to be described. Despite decades of effort and thousands of phylogenetic studies on diverse clades, we lack a comprehensive tree of life, or even a summary of our current knowledge. One reason for this shortcoming is lack of data. GenBank contains DNA sequences for ?411,000 species, only 22% of estimated named species. Although some gene regions have been widely sequenced across some lineages, they are insufficient for resolving relationships across the entire tree. Most recognized species have never been included in a phylogenetic analysis because no appropriate molecular or morphological data have been collected...

Scientists have used gene sequences and morphological data to construct tens of thousands of evolutionary trees that describe the evolutionary history of animals, plants, and microbes.
Principal investigator Karen Cranston of Duke University said, “This is the first real attempt to connect the dots and put it all together. Think of it as Version 1.0.”
