The phylogeny depicted is based on analysis of a DNA sequence alignment (13.9 kb after removal of ambiguous regions) of nuclear and mitochondrial genes from Solenodon paradoxus and 42 other eutherian taxa20, and a separate analysis of 1.6 kb of mtDNA that included S. cubanus (Supplementary Information). Only eulipotyphlan taxa are depicted, with nodes positioned on the basis of divergence times estimated by the Thorne–Kishino method21,22 using twelve fossil constraints20 (Supplementary Information). Shading along each node indicates the 95% credibility interval for the estimated divergence dates. Nodes are labelled with maximum-likelihood bootstrap support; relationships depicted were also supported by maximum-parsimony, minimum-evolution and bayesian analyses (Supplementary Information). Geological events indicated include severing of the proto-Antillean land connection to the North American mainland 70–80 Myr ago3,7, the Cretaceous/Tertiary (K/T) boundary, widespread subsidence of Caribbean islands in the Tertiary3,4,7,26, and the separation of eastern Cuba and northern Hispaniola, which began subsequent to 25–27 Myr ago3,4,7.
