| Outline of Final Research Achievements |
The development of musculoskeletal connections in vertebrates and its relationship with the evolutionary changes were studied. We analyzed the developmental process of tendons in the forelimbs of four tetrapod taxa, based on Scx expression patterns, and built a foundation of future researches on the relationship between developmental variability and evolvability. In addition, as an unexpected result, we found that in the evolution towards the turtles, the pectoralis muscle released the connection with the skeletal system and made a connection with the dermis covering the plastron.
