[3AS-10]【J】Hone-Hone rock: The diverse skeletogenesis orchestrated by various animals

Fri. Dec 5, 2025 9:00 AM - 11:00 AM JST
Fri. Dec 5, 2025 12:00 AM - 2:00 AM UTC
Room 10(Pacifico Yokohama Conference Center 4F, 413)
Organizer: Yuji Atsuta (Kyushu University), Junpei Kuroda (The University of Osaka)
Animal skeletal systems exhibit remarkable diversity in shape across species. This diversity serves as the foundation for variation in body plans and behavioral patterns. However, how skeletal systems are formed and how such diversity arises remain largely unknown. This symposium aims to deepen our understanding of the origins of diverse skeletal systems by listening to the “melody of skeletogenesis" performed by a wide range of organisms, from mammals to invertebrates.
9:00 AM - 9:01 AM JST(12:00 AM - 12:01 AM UTC)
