Synovial joints were present in the common ancestor of jawed fish but lacking in jawless fish
Synovial joints, characterized by reciprocally congruent and lubricated articular surfaces separated by a cavity, can simultaneously provide mobility and load bearing. Here, we study the early evolution of synovial joints by examining the morphological, genetic, and molecular features required for the development and function of the joints in ...

On a New Fish-Jaw from the Gault Near Folkestone [PDF]
My friend Mr. Mackie has handed me an interesting little fragment of jaw, derived from the Gault at Folkestone. The length of the broken fragment of jaw measures 1⅛ inch; its absolute breadth of an inch. It contains three teeth, of which the largest is conical, incurved, exhibiting around its thickened base a series of sculptured linear depressions ...

SATB2 and MDM2 Immunoexpression and Diagnostic Role in Primary Osteosarcomas of the Jaw
Primary osteosarcomas of the jaw (OSJ) are rare, accounting for 6% of all osteosarcomas. This study aims to determine the value of SATB2 and MDM2 immunohistochemistry (IHC) in differentiating OSJ from other jawbone mimickers, such as benign fibro-osseous

The acquisition of movable jaws was a major event during vertebrate evolution. The role of NK3 homeobox 2 (Nkx3.2) transcription factor in patterning the primary jaw joint of gnathostomes (jawed vertebrates) is well known, however knowledge about its ...

Trophic divergence of Lake Kivu cichlid fishes along a pelagic versus littoral habitat axis
Local adaptation to the littoral and pelagic zones in two cichlid haplochromine fish species from Lake Kivu was investigated using morphometrics. Cranial variation and inferred jaw mechanics in both sexes of the two species across the two habitat types ...

Gill developmental program in the teleost mandibular arch
Whereas no known living vertebrate possesses gills derived from the jaw-forming mandibular arch, it has been proposed that the jaw arose through modifications of an ancestral mandibular gill. Here, we show that the zebrafish pseudobranch, which regulates
