Abstract excerpt
Land vertebrates today comprise amniotes and lissamphibians, which have highly different modes of gas exchange, and distinct skull shapes and body size distributions. A central hypothesis of tetrapod evolution proposes a connection between these traits during their initial divergence, 335 million years ago. However, this has yet to be tested in a broad phylogenetic context. We investigate the evolution of body...
