Heads, Jaws, and Muscles: Anatomical, Functional, and Developmental Diversity in Chordate Evolution (Hardcover, 2019)

Table of contents: Introduction - Ziermann, Diaz, Diogo - Janine M. Ziermann: Howard University College of Medicine, Dept. Anatomy, - Rui Diogo: Howard University College of Medicine, Dept. Anatomy, - Raul E. Diaz Jr.: La Sierra University, Dept. Biology; Why is this book interesting for a broad audience? - Presenting, some extreme cases of heads: o size: elephant - largest land mammal, blue whale - largest mammal in general; Paedophryne amauensis - smallest vertebrate and smallest amphibian; smallest fish is Paedocypris progenetica o feeding adaptations: filter feeder (e.g., amphioxus, most forage fish, baleen whales, flamingos) herbivores, carnivore, omnivore (e.g., giraffe, lion, bear; or cow, alligator, rhea) microphagues, megalophagues (e.g., filter feeders vs. Lepidobatrachus - can eat prey its own size!) - Diversity of not only feeding modes but also sensory adaptations (e.g., large orbits for nocturnal or deep see specimens) - All vertebrates are linked - evo-devo! o recent discoveries show that some developmental mechanisms are conserved from earliest chordate to humans (e.g., cardiopharyngeal field) - This book is for everyone that has interest in the diversification, evolution and development of "Heads, Jaws and Muscles". o Present idea about emergence of new head at end BUT with Amphioxus and urochordates having already many components of vertebrate head, such as branchiomeric muscles, gills in amphioxus, etc. o So emerging question (for the purpose of the story) Where / When did the head evolve? Include fossils, etc. Chapters 1. Cephalochordates - Daniel Aldea, Stephanie Bertrand & Hector Escriva UPMC Univ Paris 06, UMR 7232, BIOM, Observatoire Oceanologique de Banyuls sur Mer Amphioxus already has a head (branchiomeric) muscles and other head structures (gills etc.) refer to recent studies of muscle development of Yasui et al., of Hector's team on anterior somites, etc. Urochordates and their importance for understanding the evolution of the vertebrate head and head muscles - Rui Diogo ; Howard University College of Medicine Urochordates closest relatives to vertebrates What do they teach us about evolution and development in vertebrates? cardiopharyngeal field, etc. Early vertebrate and gnathostome fossils, and the emergence of jaws: You three, any order of names is ok for us Zerina Johanson ; Dept. Earth Sciences, Natural History Museum London , Kate Trinajstic; Dept. Environment and Agriculture, Curtin University, Bentley, Western Australia; Per E. Ahlberg ; Department of Organismal Biology, Uppsala University What are the main "innovations" towards vertebrates, and then towards gnathostomes? Summary of fossils, etc. Where did the jaw come from? Fossils and associated muscles, etc.Transitions to vertebrates, including fossils? - Cyclostomes - Janine Ziermann ; Howard University College of Medicine, Dept. Anatomy) Ziermann & Diogo's suggested ideas to head/neck muscle evolution in cyclostomes and compared to gnathostomes inferred plesiomorphic muscle repertoire Miyashita's idea about derived similarity of mandibular and other branchial arches Chondrichthyans - Peter Johnston ; Department of Anatomy with Radiology, University of Auckland & Catherine Boisvert ; Australian Regenerative Medicine Institute (ARMI), EMBL Monash University What makes them so special? Actinopterygians - Allesia Huby & Eric Parmentier ; Laboratoire Morphologie Fonctionnelle et Evolutive Institut de Chimie Actinopterygians are the most diverse vertebrates, diverse - some with highly specialized heads and jaws and associated muscles Sarcopterygians - Alice Clement ; Flinders University, Biological Sciences Adaptations that come in handy for water-land-transition? Focus on head/neck and head/neck muscles. Include transition to tetrapods Amphibians - Janine Ziermann ; Howard University College of Medicine, Dept. Anatomy Present diversity of head / neck s
