Abstract excerpt
The spine is a defining feature of the vertebrate body plan. However, broad differences in vertebral structures and morphogenetic strategies occur across vertebrate groups, clouding the homology between their developmental programs. Analysis of a zebrafish mutant, spondo, whose spine is dysmorphic, prompted us to reconstruct paleontological evidence, highlighting specific transitions during teleost spine...
