Phylogenetic analysis of Mexican cave scorpions suggests adaptation to caves is reversable
New evidence that specialized adaptations are not evolutionary dead endsBlind scorpions that live in the stygian depths of caves are throwing light on a long-held assumption that specialized adaptations are irreversible evolutionary dead-ends. According to a new phylogenetic analysis of the family Typhlochactidae, scorpions currently living closer to the surface (under stones and in leaf litter) evolved independently on more than one occasion from ancestors adapted to life further below the surface (in caves). The research, currently available in an early online edition, will be published in the April issue of Cladistics."Our research shows that the evolution of troglobites, or animals adapted for life in caves, is reversible," says Lorenzo Prendini, Associate Curator in the Division of Invertebrate Zoology at the American Museum of Natural History. "Three more generalized scorpion species living closer to the surface evolved from specialized ancestors living in caves deep below the surface.&qu
