title: Phylogenetic tree of tRNAs using a simple algorithm.
abstract: A simple method for phylogenetic tree construction is described. In this method each node is calculated considering the distance between the elements and the difference between these elements and an average element, allowing the selection of the most probable node. Two examples of tRNA phylogenies (E. coli set and Phe family) are analyzed, giving both reliable trees. Data from these dendrograms give support to the idea of an early cloverleaf arising.
