The field of evolutionary developmental biology (Evo-Devo) has been profoundly shaped by a handful of classical model organisms — such as Drosophila melanogaster, Caenorhabditis elegans, zebrafish, mouse, and Arabidopsis — which have provided fundamental insights into the genetic and molecular mechanisms underlying development. However, relying solely on these few models has also imposed epistemological and practical limitations, particularly when it comes to addressing the diversity of developmental processes and evolutionary trajectories found across the tree of life. As Evo-Devo matures, there is a growing recognition of the need for new model systems that better capture the breadth of evolutionary innovations, ecological contexts, and phenotypic plasticity.
This volume continues to advocate the use of strategically diversified model systems as tools for filling existing gaps. It also explores the philosophical, methodological and practical considerations in the search for new model species in Evo-Devo, highlighting recent successes, ongoing challenges, and the full potential of expanding the repertoire of model species.
The book offers readers a fresh perspective on developmental processes and their natural diversity among different animal groups, fostering a deeper understanding. It broadens the horizons of experienced researchers and those just starting out in the field.

Waclaw Tworzydlo is an associate professor at the Institute of Zoology and Biomedical Research at the Jagiellonian University in Krakow, specialising in zoology and developmental biology.
Szczepan M. Bilinski is currently Secretary General of the Polish Academy of Arts and Sciences and Professor Emeritus of the Institute of Zoology and Biomedical Research, Jagiellonian University, Krakow. His scientific expertise includes zoology, developmental biology and cell biology.
Waclaw Tworzydlo and Szczepan M. Bilinski are the editors of this volume, which brings together different perspectives on the expanding field of Evo-Devo. They both use a range of non-model insects in their research, and their combined expertise guides the exploration of new model systems and their potential to revolutionise our understanding of development and evolution.
