Abstract
This special issue of Systematic Biology contains review articles contributed by keynote speakers at the “Mathematical and Computational EvolutionaryBiology” conference (MCEB; see web sites below), held in 2015. This is the seventh conference in this series, the first being held in Paris in 2003 with keynote addresses from such notables as Joe Felsenstein, Ziheng Yang, and Walter Fitch. Oxford University Press published two books based on the 2003 and 2005 Paris meetings (Gascuel 2005; Gascuel and Steel 2007).
