 The first centralized nervous system and bilateral symmetry appeared during early Cambrian about 650 million years ago. These ancient innovations led to the evolution of complex life cycles, behaviour and played a major role in establishing the diversity of extant animals. My project focuses on the characterization of such long-term evolutionary processes from a multiscale perspective, i.e. by studying molecular development of cell types in a context of population/ecosystem evolution and  comparative genomics. In my talk I will introduce our primarily working system (marine polychaete Platynereis sp), the ongoing molecular and morphological cell type characterization, and give a brief overview of population and comparative genomics studies and their first results.
