Perfect phylogeny is one of the fundamental models for studying evolution. We investigate the following variant of the problem: The input is an n ×m species-characters matrix. The characters are binary and directed, i.e., a species can only gain characters. The difference from standard perfect phylogeny is that for some species the state of some characters is unknown. The question is whether on...
L. Vigilant et al. (1) recently presented "the strongest support yet for the placement of [their] common mtDNA [mitochondrial DNA] ancestor in Africa some 200,000 years ago." This support stems from a tree estimated by maximum parsimony from mtDNA sequence data with the use of the computer program PAUP (2). The African origin is inferred from this tree because (i) the most basal splits are amon...
