    Abstract : Onychophorans are closely allied to the arthropods and possess a body organisation more similar to Middle Cambrian fossils than to recent arthropods. This means that onychophorans in some respects can be regarded as a model for the last common ancestor to both the Arthropoda and the Onychophora. READ MORE

  2. 2. Investigation of Hox gene expression and Wnt-signalling in basally branching ecdysozoans

    Abstract : One of the most important processes in the development of an animal is the determination and patterning of the primary body axis, the anterior-posterior (AP) axis. After the AP axis has been established the embryo grows and elongates through posterior elongation. READ MORE
