We examined available chromosome painting data to identify conserved chromosomes and chromosomal segments, and syntenic associations likely to have characterized the ancestral eutherian karyotype. The data set includes 161 characters that have been subjected to a concatenated analysis using maximum parsimony (MP) and Bayesian inference (BI). The phylogenetic pattern recovered is generally consistent with reconstructions based on molecular and morphological data (particularly with respect to higher systematic groupings), but there are several anomalies (e.g., in the position of the lagomorphs). Both MP and BI topologies have weak statistical support, as a consequence of the high number of autapomorphic and homoplastic character states that have evolved during the history of the clade. The vast majority of derived associations are located on the terminal portions of the branches, and very few can be identified to support deeper divergences in the tree, indicating that chromosomal structures are far more fluid that was previously recognized. The high levels of homoplasy reflected in our data suggest that the number of possible syntenic character states is limited by chromosomal structures, and the same associations occur repeatedly.
