A new technique for identifying sequence heterochrony.
Sequence heterochrony (changes in the order in which events occur) is a potentially important, but relatively poorly explored, mechanism for the evolution of development. In part, this is because ofExpand

A supertree of early tetrapods
A genus–level supertree for early tetrapods is built using a matrix representation of 50 source trees. The analysis of all combined trees delivers a long–stemmed topology in which most taxonomicExpand

Analyzing developmental sequences within a phylogenetic framework.
Heterochrony is important as a potential mechanism of evolutionary change. However, the analysis of developmental timing data within a phylogenetic framework to identify important shifts has provenExpand

Pectoral fins of rhizodontids and the evolution of pectoral appendages in the tetrapod stem-group
Abstract The Rhizodontida are an extinct order of large, predatory, lobe-finned fishes, found world-wide in Devonian and Carboniferous freshwater deposits. They are thought to be basal members of theExpand

Analyzing evolutionary patterns in amniote embryonic development *
SUMMARY Heterochrony (differences in developmental timing between species) is a major mechanism of evolutionary change. However, the dynamic nature of development and the lack of a universal timeExpand

Forelimb-hindlimb developmental timing changes across tetrapod phylogeny
BackgroundTetrapods exhibit great diversity in limb structures among species and also between forelimbs and hindlimbs within species, diversity which frequently correlates with locomotor modes andExpand

Fins to limbs: what the fossils say 1
SUMMARY A broad phylogenetic review of fins, limbs, and girdles throughout the stem and base of the crown group is needed to get a comprehensive idea of transformations unique to the assembly of theExpand

From Haeckel to event-pairing: the evolution of developmental sequences
Sequence heterochrony can be used to extract important biological information from developmental sequences by mapping them onto established phylogenies. Expand

ABSTRACT The Rhizodontida (Pisces: Sarcopterygii) is a clade of predatory fishes from the Upper Devonian (Aztecia; ?Givetian of Antarctica) through to the Upper Carboniferous (Strepsodus; MoscovianExpand
