imageFigure S1 in the study presents the best maximum likelihood tree of the Teleostei, generated from the '123ryRT' mitochondrial sequence data subset using the software RAxML, with branch lengths proportional to the number of substitutions per nucleotide position.

imageIn the maximum likelihood tree of the Teleostei generated by the study, the Mormyroidea (African weakly electric fishes) and the Gymnotiformes (South American weakly electric fishes) are highlighted.

Hopkins published 'AFLPs resolve phylogeny and reveal mitochondrial introgression within a species flock of African electric fish (Mormyroidea : Teleostei)' in Evolution in 2004, using AFLP markers to study the phylogeny of African electric fish.

claimMaximum likelihood (ML) analyses consistently show that Gymnotiformes and Mormyroidea are each monophyletic groups to the exclusion of all other teleosts, with a bootstrap proportion of 100%.

procedureUnder the second calibration strategy (reconstruction #2), prior age distributions of selected nodes follow a uniform distribution where the minimum age limit is the minimum age of the stratum from which the fossil was excavated, and the maximum age limit is the minimum age of the root of the tree.

claimThe first calibration strategy (reconstruction #1) assumes that while the fossil records of some Teleostei groups provide only minimum age limits, the fossil records of other groups are sufficiently rich to provide both minimum and maximum age limits.

referenceSullivan JP, Lavoué S, and Hopkins CD (2000) developed a molecular systematics study of African electric fishes (Mormyroidea: Teleostei) and proposed a model for the evolution of their electric organs.

procedureUnder the first calibration strategy (reconstruction #1), prior age distributions of fossil-calibrated nodes are mixed: they follow either a uniform distribution (where the minimum age limit is the stratum's minimum age and the maximum age limit is the root's minimum age) or a lognormal distribution (where the minimum age is the stratum's minimum age and the maximum age is the stratum's maximum age).

claimThe fossil †Brachydegma caelatum (Amiiformes) constrained the age of the stem-group Teleostei.

claimThe maximum likelihood tree of the Teleostei in the study is rooted with the species Amia calva.

referencePeng et al. (2006) provided new insights into the origin of major Otocephalan clades (Pisces: Teleostei) using mitochondrial molecular clocks.

referenceThe study titled 'Comparable Ages for the Independent Origins of Electrogenesis in...' utilized the software RAxML to generate a maximum likelihood tree of the Teleostei from the mt-seq data subset '123RT', where branch lengths represent the number of substitutions per nucleotide position.

referenceLavoué S, Miya M, Poulsen JY, Moller PR, and Nishida M (2008) analyzed the monophyly, phylogenetic position, and inter-familial relationships of the Alepocephaliformes (Teleostei) using whole mitogenome sequences in 'Molecular Phylogenetics and Evolution', volume 47, pages 1111–1121.

referenceLavoué S and Sullivan JP (2004) performed a simultaneous analysis of five molecular markers to create a phylogenetic hypothesis for living bony-tongue fishes (Osteoglossomorpha: Teleostei).

claimThe two clades of weakly electric fishes, Gymnotiformes and Mormyroidea, are nested within two distantly related groups of Teleostei: the Ostariophysi and the Osteoglossomorpha.

referenceLavoué S, Sullivan JP, and Hopkins CD (2003) analyzed the phylogenetic utility of the first two introns of the S7 ribosomal protein gene in African electric fishes (Mormyroidea: Teleostei) and compared these findings with other molecular markers.

claimThe second calibration strategy (reconstruction #2) assumes that the overall fossil record of the Teleostei is incomplete and provides only minimum ages for the origins of selected groups.
