Evidence for the prepattern/cooption model of vertebrate jaw evolution
The appearance of jaws was a turning point in vertebrate evolution because it allowed primitive vertebrates to capture and process large, motile prey. The vertebrate jaw consists of separate dorsalExpand

A New Mechanistic Scenario for the Origin and Evolution of Vertebrate Cartilage
The appearance of cellular cartilage was a defining event in vertebrate evolution because it made possible the physical expansion of the vertebrate “new head”. Despite its central role in vertebrateExpand

Developmental origins and evolution of jaws: new interpretation of "maxillary" and "mandibular".
Cartilage of the vertebrate jaw is derived from cranial neural crest cells that migrate to the first pharyngeal arch and form a dorsal "maxillary" and a ventral "mandibular" condensation. It has beenExpand

The odontode explosion: The origin of tooth‐like structures in vertebrates
Essentially we show recent data to shed new light on the thorny controversy of how teeth arose in evolution. Essentially we show (a) how teeth can form equally from any epithelium, be it endoderm,Expand

Development and evolution of the vertebrate primary mouth
The vertebrate oral region represents a key interface between outer and inner environments, and its structural and functional design is among the limiting factors for survival of its owners. BothExpand

Dual epithelial origin of vertebrate oral teeth
The oral cavity of vertebrates is generally thought to arise as an ectodermal invagination. Consistent with this, oral teeth are proposed to arise exclusively from ectoderm, contributing to toothExpand

The origin and diversification of the developmental mechanisms that pattern the vertebrate head skeleton.
The apparent evolvability of the vertebrate head skeleton has allowed a diverse array of shapes, sizes, and compositions of the head in order to better adapt species to their environments. ThisExpand

Roles for FGF in lamprey pharyngeal pouch formation and skeletogenesis highlight ancestral functions in the vertebrate head
A defining feature of vertebrates (craniates) is a pronounced head supported and protected by a cellularized endoskeleton. In jawed vertebrates (gnathostomes), the head skeleton is made of rigidExpand

Electron microscopy of the amphibian model systems Xenopus laevis and Ambystoma mexicanum.
In this chapter we provide a set of different protocols for the ultrastructural analysis of amphibian (Xenopus, axolotl) tissues, mostly of embryonic origin. For Xenopus these methods include: (1)Expand

Pre-oral gut contributes to facial structures in non-teleost fishes
Despite the wide variety of adaptive modifications in the oral and facial regions of vertebrates, their early oropharyngeal development is considered strictly uniform. It involves sequentialExpand
