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

The earliest tetrapod limbs are polydactylous, morphologically varied and do not conform to
an archetypal pattern. These discoveries, combined with the unravelling of limb …

During development of the limbs, Hox genes belonging to the paralogous groups 9–13 are
expressed in three distinct phases, which play key roles in the segmental patterning of limb …

The expression and function of hox genes have played a key role in the debate on the
evolution of limbs from fins. As an early branching tetrapod lineage, lissamphibians may …

During development, expression of the Hoxa and Hoxd genes in zebrafish fins and mouse
limbs are regulated via a conserved chromatin structure. However, zebrafish lack certain …

Paleontological and anatomical evidence suggests that the autopodium (hand or foot) is a
novel feature that distinguishes limbs from fins, while the upper and lower limb (stylopod and …

The evolutionary transition of fins to limbs involved development of a new suite of distal
skeletal structures, the digits. During tetrapod limb development, genes at the 5′ end of the …

The dorsal and anal fins can vary widely in position and length along the anterior–posterior
axis in teleost fishes. However, the molecular mechanisms underlying the diversification of …

More than three centuries ago natural philosophers, and later anatomists, recognized a
fundamental organization to the skeleton of tetrapod limbs. Composed of three segments …

There is no obvious morphological counterpart of the autopod (wrist/ankle and digits) in
living fishes. Comparative molecular data may provide insight into understanding both the …
