Bapx1 is required for jaw joint development in amphibians
It is shown that bapx1 plays a role in jaw joint maintenance during development and that the morphants morphology possibly mirrors the morphology of the jawless ancestors of the gnathostomes.
Bapx1 upregulation is associated with ectopic mandibular cartilage development in amphibians
Observations imply a joint-promoting function of bapx1, which further substantiates its hypothetical role in the evolution of the gnathostome jaw joint.

Sequence and timing of early cranial skeletal development in Xenopus laevis
Xenopus laevis is widely used as a model organism in biological research. Morphological descriptions of the larval cartilaginous skeleton are more than half a century old and comprehensive studies of…
The Biogenetic Law and the Gastraea Theory: From Ernst Haeckel´s Discoveries to Contemporary Views
More than 150 years ago, in 1866, Ernst Haeckel published a book in two volumes called "Generelle Morphologie der Organismen" (General Morphology of Organisms) in the first volume of which he…
Sequence of chondrocranial development in the oriental fire bellied toad Bombina orientalis
The vertebrate head as a major novelty is directly linked to the evolutionary success of the vertebrates. Sequential information on the embryonic pattern of cartilaginous head development are scarce,…
