Open lecture: Holobiont Evo-Devo: How Symbionts might direct evolutionary trajectories

Professor Gilbert is a pioneering figure in the fields of evolutionary developmental biology (evo-devo) and ecological developmental biology (eco-devo). His research has explored the mechanisms of turtle shell formation, revealing the role of trunk neural crest cells in the development of the plastron. Additionally, he has been instrumental in conceptualizing the holobiont—the host and its symbiotic microbes considered as a single unit of developmental and evolutionary significance.

In his lecture, Professor Gilbert will present new material on holobiont evo-devo, discussing how symbionts can:

• provide new, selectable phenotypes,
• initiate the formation of new organs,
• and cause reproductive isolation.

Lecture is open to all.
Coffee and cookies will be available.

---------------

Professor Scott F. Gilbert is evolutionary developmental biologist and historian of biology. He is the Howard A. Schneiderman Professor of Biology (emeritus) at Swarthmore College and Finland Distinguished Professor (emeritus) at the University of Helsinki.

His book Developmental Biology (first published 1985; now in the 13th edition, 2023), often regarded as the classic, is widely used developmental biology textbook.

Gilbert’s foundational research includes demonstrating the first pyrimidine-initiated RNA transcription sites in E. coli, exploring how antibodies neutralize poliovirus to deepen insights into viral immunology, and examining paracrine signaling mechanisms involved in organ branching during embryonic development.

Interdisciplinary Impact

Prof. Gilbert has integrated social critique and philosophy into biology, writing on feminist critiques, bioethics, the history of embryology, and the intersection of art and science.
