概要 | Germ layer patterning and body axis formation are central issues in vertebrate embryology that can be examined in some model animals. An intriguing question is how the mechanisms that existed in an ancestral vertebrate have been modified during vertebrate evolution. A major stream of vertebrates (Osteichthyes = bony fishes) evolved into two monophyletic lineages: Sarcopterygii, including amphibians and amniotes, and Actinopterygii (ray-finned fishes), including teleosts as the crown group. Bichir diverged from all other actinopterygians soon after this divarication. Therefore, bichir is uniquely well suited for studies assessing the ancestral state of Osteichthyes/Actinopterygii as well as understanding the divergence of embryogenesis in teleosts and amphibians.--- |
