Comparative analyses of Hox gene expression and regulation in teleost fish and tetrapods
support the long-entrenched notion that the distal region of tetrapod limbs, containing the …

HOX genes are essential for growth and patterning of the tetrapod limb skeleton1–5. Mice
mutant for the Hoxd-13 gene have an important delay in morphogenesis owing to reduced …

SIR-Fore and hind limbs of landdwelling vertebrates have very similar structures despite
having been independently derived from different fins of fish. We suggest that Hox genes …

The fin-to-limb transition represents one of the major vertebrate morphological innovations
associated with the transition from aquatic to terrestrial life and is an attractive model for …

AMONG THE FiRST fossil finds to pave the way for our modern conception of tetrapod
origins were those of a creature called Acanthostega, which lived about 360 million years …

The development of jaws was a critical event in vertebrate evolution because it ushered in a
transition to a predatory lifestyle, but how this innovation came about has been a mystery. In …

Cephalopods are a diverse group of highly derived molluscs, including nautiluses, squids,
octopuses and cuttlefish. Evolution of the cephalopod body plan from a monoplacophoran …

The clustered organization of Hox genes provides a powerful opportunity to examine gene
gain and loss in evolution because physical linkage is a key diagnostic feature which allows …

Limb Evolution: Fish fins or tetrapod limbs — a simple twist of fate?: Current Biology Skip to Main

Fingers and toes were long thought to be novelties associated with the invasion of land by
tetrapods. The recent identification of a variety of aquatic specializations in some early …
