Evolutionary biologists observe parallel, repeated evolution of cichlid fish in Nicaragua

28 octubre 2014

If one would rewind the tape of life, would evolution result in the same outcome? An evolutionary biologist came up with this famous question. He suggested that evolution would not repeat itself: the role of random processes in the origin of biodiversity was too important and hence evolution was not predictable. Evolutionary biologists have now described parallel evolution of two closely related, but geographically isolated populations of cichlid fish in Nicaraguan crater lakes.
