A cladistic analysis of the South American members of the family Leptohyphidae is presented. A matrix of 73 taxa and 124 morphological characters was analyzed under two distinct weighting criteria (implied weighting, which ...

Quantitative and continuous characters have rarely been included in cladistic analyses of morphological data; when included, they have always been discretized, using a variety of ad hoc methods. As continuous characters ...

This paper discusses the problem of whether creating a matrix with all the character state combinations that have a fixed number of steps (or extra steps) on a given tree T, produces the same tree T when analyzed with ...

Modern phylogenetic comparative biology uses data from the relationships between species (phylogeny) combined with comparative information for phenotypic traits to draw model?based statistical inferences about the evolutionary ...
