measurementThe estimated time interval between the origins of teleost electroreception and the origins of electrogenesis is 22.7 million years for mormyroids and 25.6 million years for gymnotiforms under reconstruction #2.
referenceHopkins CD (1995) identified convergent designs for electrogenesis and electroreception in fish.
claimGymnotiforms and mormyroids originated independently from non-electrogenic ancestors at approximately the same period in Earth's history.
claimGene duplication is considered an important source of raw material for the origin of novel traits, including electrogenesis in teleosts.
claimIn both Gymnotiformes and Mormyroidea, a similar duration of time elapsed between the initial origin of electroreception and the subsequent origin of electrogenesis, which was accompanied by the evolution of more complex electroreceptive systems.
referenceThe study titled 'Comparable Ages for the Independent Origins of Electrogenesis in Teleosts' analyzed a single molecular dataset including representatives of South American Gymnotiformes and African Mormyroidea to infer the ages of their independent origins of electrogenesis.
measurementThe estimated time interval between the origins of teleost electroreception and the origins of electrogenesis is 16.6 million years for mormyroids and 18.7 million years for gymnotiforms under reconstruction #1.
claimThe research study on the origins of electrogenesis in weakly electric fishes was funded by the Japan Society for the Promotion of Science Research Grants (Nos. 16570082, 15380131, 17207007, 19207007 and 22370035).
claimThe ability to sense low-frequency, passive electric fields preceded the evolution of electrogenesis in Gymnotiformes and Mormyroidea.
claimThe nodes representing the two independent origins of electrogenesis in weakly electric teleosts received extremely strong topological support across all data subsets and analyses.
claimThe Gymnotiformes and Mormyroidea lineages evolved electrogenesis independently but contemporaneously, occurring tens of millions of years after their most recent common ancestor.
claimStoddard proposed that adaptations involving electrogenesis and electroreception in electric fish serve the purpose of avoiding predation by other electroreceptive species.
claimThe independent origins of electrogenesis in weakly electric fishes may have occurred after roughly the same intervals of time following the independent origins of teleost electroreception.

claimActive electrolocation involves an animal generating weak electric fields through electrogenesis and detecting distortions in those fields using electroreceptor organs.
claimElectroreception is the biological ability to perceive electrical stimuli, while electrogenesis is the biological ability to generate electric fields.
claimElectroreception and electrogenesis are found almost exclusively in aquatic or amphibious animals because water is a significantly better conductor of electricity than air.

claimElectrogenesis, defined as the biological production of an electric field, is performed by modified muscle and nerve tissues in both strongly and weakly electric fish.
