The file containing all the 2,065 cytochrome b sequences, along with their accession numbers, can be downloaded here in Nexus format.

The 32 groups we used are defined as follows:


All the analyses were performed using an internal fragment (335 a.a., from FGSLL to LILMP in the human sequence) of the cytochrome b (380 a.a.). We discarded the two extremities of the sequences, which are unknown in many species.

Simulations of the 200-taxa data sets were performed by Fitch's program simtree, using this file as the tree definition. Simtree is available from Walter Fitch upon request.
