paedomorphic การใช้

• Paedomorphic species are mainly aquatic, while peramorphic species are mainly terrestrial.
• The species is also paedomorphic, with mature adults retaining some characteristics of larvae.
• Female-like ( paedomorphic ) males apparently also occur, at least in some species.
• This is a paedomorphic and either fail to complete their metamorphosis or retain some larval characteristics as adults.
• By 2011, the finding by the same researcher was simply " Dogs are not paedomorphic wolves ."
• Axolotls live in a paedomorphic state, retaining most characteristics of their larval stage for their entire lifespans.
• Paedomorphic individuals breed as larvae, but some individuals continue to develop and undergo metamorphosis in the usual way.
• It is considered that " X . medusiformis " may be paedomorphic, retaining larval characteristics into adulthood.
• The generic name is a reference to the paedomorphic habit of this genus, which retains many larval features throughout its life.
• What little is known of barreleye reproduction indicates they are pelagic paedomorphic features, the result of neoteny ( the retention of larval characteristics ).
• The pelvic elements were thicker than those of flighted pigeons to support the higher weight, and the paedomorphic, meaning that they were underdeveloped and retained juvenile features.
• Their pelvic elements were thicker than those of flighted birds ( to support their greater weight ), and their pectoral region and wings were paedomorphic ( underdeveloped, retaining juvenile features ).
• Like these other genera, " K . rotundata " has only three thoracic segments, probably due to paedomorphic dwarfism : other raphiophorid trilobites have at minimum five thoracic segments.
• The study also provides support for Stephen Jay Gould's theory in " Ontogeny and Phylogeny " that the paedomorphic form of early hominin craniofacial morphology results from heterochronic dissociation of growth trajectories.
• The eye remnants are extremely reduced in size with very little or no trace of a retina or paedomorphic traits ( indicated by small size, kidney morphology, and weak ossification of the skeleton ).
• Wayne ( 1986 ) concluded that his dog samples did not have significant relative shortening of the rostrum compared to wolves, calling this identification feature into question . " Dogs are not paedomorphic wolves ."
• "C . oliveirai " has been found to be a paedomorphic species of the genus " Cetopsis ", with many traits similar to juveniles of " C . coecutiens ".
• This study demonstrated affinities between the skull morphology of " Ar . ramidus " and that of infant and juvenile chimpanzees, suggesting the species evolved a juvenalised or paedomorphic craniofacial morphology via heterochronic dissociation of growth trajectories.
• A study comparing embryonic, juvenile and adult archosaur skulls concluded that bird skulls are derived from those of theropod dinosaurs by progenesis, a type of paedomorphic heterochrony, which resulted in retention of juvenile characteristics of their ancestors.
• Even though none of the neural arches are fused to their centra in the vertebral column of both individuals ( a possible juvenile trait ), this feature is present in all large pliosaurids, and thus possibly paedomorphic within Pliosauridae.
