    J G M Thewissen
    Department of Anatomy, Northeastern Ohio Universities College of Medicine, Rootstown, Ohio 44272, USA
    Nature 450:1190-4. 2007
    ..We also show that a major dietary change occurred during the transition from artiodactyls to whales and that raoellids were aquatic waders. This indicates that aquatic life in this lineage occurred before the origin of the order Cetacea...
  2. ncbi request reprint Skeletons of terrestrial cetaceans and the relationship of whales to artiodactyls
    J G Thewissen
    Department of Anatomy, Northeastern Ohio Universities College of Medicine, Rootstown, Ohio 44272, USA
    Nature 413:277-81. 2001
    ..Cetaceans are not the sister group to (any) mesonychians, nor to hippopotamids. Our analysis stops short of identifying any particular artiodactyl family as the cetacean sister group and supports monophyly of artiodactyls...
  3. pmc Developmental basis for hind-limb loss in dolphins and origin of the cetacean bodyplan
    J G M Thewissen
    Department of Anatomy, Northeastern Ohio Universities College of Medicine, Rootstown, OH 44272, USA
    Proc Natl Acad Sci U S A 103:8414-8. 2006
    ..Hence, macroevolutionary changes in gene expression did not drive the initial reduction in hind-limb size...
  4. ncbi request reprint Ankle morphology of the earliest Cetaceans and its implications for the phylogenetic relations among ungulates
    J G Thewissen
    Department of Anatomy, Northeastern Ohio Universities College of Medicine, Rootstown, Ohio 44240, USA
    Syst Biol 48:21-30. 1999
    ..Tarsal data do not support Cete (Mesonychia plus Cetacea) and are consistent with the exclusion of perissodactyls from paenungulates as suggested by some molecular studies...
  5. ncbi request reprint Rotation of middle ear ossicles during cetacean development
    M D Kinkel
    Department of Anatomy, Northeastern Ohio Universities College of Medicine, Rootstown, Ohio 44272, USA
    J Morphol 249:126-31. 2001
    ..Therefore, some of the unique characteristics of the cetacean middle ear develop as modifications of an initially terrestrial-like morphology...
  6. ncbi request reprint Eocene evolution of whale hearing
    Sirpa Nummela
    Department of Anatomy, Northeastern Ohio Universities College of Medicine, Rootstown, Ohio 44272, USA
    Nature 430:776-8. 2004
    ..The mechanism of these fossil whales lacks sophistication, and still retains some of the key elements that land mammals use to hear airborne sound...
  7. ncbi request reprint Sound transmission in archaic and modern whales: anatomical adaptations for underwater hearing
    Sirpa Nummela
    Department of Anatomy, Northeastern Ohio Universities College of Medicine, Rootstown, Ohio, USA
    Anat Rec (Hoboken) 290:716-33. 2007
    ..The land mammal ear and the generalized modern whale ear are evolutionarily stable configurations, two ends of a process where the cetacean mandible might have been a keystone character...
  8. ncbi request reprint Morphoregulation of teeth: modulating the number, size, shape and differentiation by tuning Bmp activity
    Maksim V Plikus
    Department of Pathology, Keck School of Medicine, University of Southern California, Los Angeles, CA 90033, USA
    Evol Dev 7:440-57. 2005
    ..The involvement of related pathways and the implication of morphoregulation in tooth evolution are discussed...
  9. ncbi request reprint Vestibular evidence for the evolution of aquatic behaviour in early cetaceans
    F Spoor
    Department of Anatomy and Developmental Biology, University College London, Rockefeller Building, University Street, London WC1E 6JJ, UK
    Nature 417:163-6. 2002
    ..We hypothesize that the unparalleled modification of the semicircular canal system represented a key 'point of no return' event in early cetacean evolution, leading to full independence from life on land...
  10. ncbi request reprint A retroposon analysis of Afrotherian phylogeny
    Hidenori Nishihara
    Graduate School of Bioscience and Biotechnology, Tokyo Institute of Technology, Yokohama, Japan
    Mol Biol Evol 22:1823-33. 2005
    ..Our results suggest the rapid fixation of many large-scale morphological synapomorphies for Tethytheria; implications of this in relation to the morphological evolution in Paenungulata are discussed...
