Comparable Ages for the Independent Origins of Electrogenesis in ... journals.plos.org 20 facts
measurementThe interval between the appearance of electroreception and the origin of myogenic electric organs in both Gymnotiformes and Mormyroidea is estimated to be between 16 and 19 million years or 22 and 26 million years, depending on the calibration method used.
claimThe distribution of electroreception in non-teleost aquatic craniates suggests that electroreception is an ancient sense within the Craniata.
referenceHopkins CD (1995) identified convergent designs for electrogenesis and electroreception in fish.
claimResearch on the sensory capabilities of aquatic mammals that might have independently evolved electroreception is currently limited to a single captive specimen trained to respond to weak electric fields, indicating a need for further investigation.
claimAsian notopterids (Notopteroidei) are hypothesized to have lost electroreception.
claimElectroreception, specifically ampullary electroreceptors tuned to low electrical frequencies, evolved prior to the origin of myogenic electric organs.
claimThe time intervals between the appearance of electroreception and the origin of electric organs represent the upper estimates for the time required for evolution to construct a weak, myogenic electric organ from a skeletal muscle precursor.
referenceCaputi AA, Carlson BA, and Macadar O (2005) published 'Electric organs and their control' in 'Electroreception', edited by Bullock TH, Hopkins CD, Popper AN, and Fay RR, New York: Springer Science+Business Media, Inc., pp. 410–451.
referenceThe book 'Electroreception', edited by T.H. Bullock, C.D. Hopkins, A.N. Popper, and R.R. Fay, was published in 2005 by Springer Science+Business Media, Inc.
claimSelection pressures for weak electric organs likely arose only after the evolution of an electrosensory system, because electroreception is necessary to detect reafferent signals produced by electric organs.
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.
claimElectroreception is defined as the ability to sense weak electric fields.
claimIn the study, the term "origin of electroreception" refers to the initial origin of any kind of electroreceptive system in the broadest sense.
claimThe nodes defining the Notopteroidei and Characiphysae clades define minimum age estimates for the independent origins of electroreception among teleosts, specifically in the form of derived ampullary electroreceptors.
referenceHopkins CD (2010) authored an entry on 'Electroreception' in the 'Encyclopedia of Perception', published by Sage Publications.
claimWithin the Ostariophysi, the Siluriformes and the Gymnotiformes are the only electroreceptive fishes; the Characiformes, Cypriniformes, and Gonorynchiformes lack any form of electroreception.
measurementThe estimated time interval between the appearance of electroreception and the origin of myogenic electric organs is 16–19 million years under reconstruction #1, and 22–26 million years under reconstruction #2.
claimStoddard proposed that adaptations involving electrogenesis and electroreception in electric fish serve the purpose of avoiding predation by other electroreceptive species.
claimSimilar periods of time elapsed between the origin of passive electroreception and the appearance of the myogenic electric organ (and active electroreception) in both the mormyroid and gymnotiform lineages of weakly electric fishes.
claimWithin teleost fishes, electroreception is restricted to two distantly related groups: the Siluriphysi (Gymnotiformes plus Siluriformes) and the Notopteroidei (Mormyroidea plus Notopteridae).

claimMonotremes, including the platypus and echidnas, are one of the only groups of mammals that have evolved electroreception.
claimNeotropical knifefishes (Gymnotiformes) and African elephantfishes (Notopteroidei) are weakly electric and actively electroreceptive, which enables them to navigate and find food in turbid water.
referenceTheodore Holmes Bullock authored the book 'Electroreception', published by Springer in New York in 2005.
claimApteronotus fish can select and catch larger Daphnia water fleas among smaller ones and do not discriminate against artificially-darkened water fleas, regardless of the presence of light.
claimIn vertebrate groups where electroreception occurs despite the loss of ampullae of Lorenzini, the trait was secondarily acquired using non-homologous organs.
claimDolphins have evolved electroreception in structures that are different from those found in fish, amphibians, and monotremes.
measurementThe hairless vibrissal crypts on the rostrum of the Guiana dolphin (Sotalia guianensis) are capable of electroreception with a sensitivity as low as 4.8 μV/cm, which allows the dolphin to detect small fish.
claimElectroreception is the biological ability to perceive electrical stimuli, while electrogenesis is the biological ability to generate electric fields.
claimUntil recently, electroreception was known to exist only in vertebrates.
referenceJ. D. Pettigrew published a paper titled 'Electroreception in Monotremes' in the Journal of Experimental Biology in 1999.
claimElectroreception and electrogenesis are found almost exclusively in aquatic or amphibious animals because water is a significantly better conductor of electricity than air.
