Data for: Back to the roots: reducing evolutionary rate heterogeneity among sequences gives support for the early morphological hypothesis of the root of Siluriformes (Teleostei: Ostariophysi)

Gene-specific and concatenated alignments for all 10 genes used in this study. There are three versions of the concatenated data (and their corresponding gene components): 1. Full data, 2. Data after applying the LS³ algorithm, and 3. Data after applying the LS⁴ algorithm.
