  • Title: Saltational evolution of trunk segment number in centipedes.
    Author: Minelli A, Chagas-Júnior A, Edgecombe GD.
    Journal: Evol Dev; 2009; 11(3):318-22. PubMed ID: 19469859.
    Abstract:
    Saltational changes in segment numbers have likely occurred in arthropod evolution, especially if mechanisms of segment formation involve a multiplicative phase, as recently suggested in the evo-devo literature. Here we provide for the first time evidence of major phenotypic saltation in the evolution of segment number in a lineage of centipedes, with a newly discovered species of scolopender having segment numbers duplicated with respect to its closest relatives, and to all the remaining 700+ species of Scolopendromorpha known to date.
