Genomes and the Tree of Life
EVOLUTION: GENOMES AND THE TREE OF LIFE: "Although we have not yet counted the total number of species on our planet, biologists in the field of systematics are assembling the 'Tree of Life' (1,2). The Tree of Life aims to define the phylogenetic relationships of all organisms on Earth.
Computer simulation studies (5) recently showed that, contrary to the prevailing view, phylogenetic accuracy depends more on having sufficient characters (such as amino acids) than on whether data are missing. Clearly, building a super-tree allows for an abundance of characters even though there are many missing entries in the resulting matrix." K.A. Crandall and J.E. Buhay (Science 2004 306:1144)
