Homeosis and Beyond. What Is the Function of the Hox Genes?e, examining its various meanings at different levels of biological organization. I will review and revisit the relation between the Hox genes and homeosis. I will suggest that their morphological homeotic function has been secondarily derived during the evolution of the Bilateria.

Hox Genes and the Body Plans of Chelicerates and Pycnogonidslving longstanding zoological questions. In this chapter I summarize Hox gene data from chelicerates, including the enigmatic pycnogonids (sea spiders) and how these data have helped us to understand the body plans of different arthropod taxa.
