Arthropod segmentation: why centipedes are odd.
Abstract
Recent work has revealed a double segmental periodicity of gene expression in the centipede, a potential molecular explanation for the observation that this arthropod always has an odd number of trunk segments. Is this an oddity of centipedes, or might it mean that double segmental pair-rule patterning dates back to the Ur-arthropod?
