The secondary xylem of Caricaceae, despite its parenchymatization and succulence, is not really juvenilistic in most features, showing that paedomorphosis and succulence do not necessarily go together.
Approximately 10% of all species of salamander express either obligate or facultative paedomorphosis (Lanoo, 2005).
This phenomenon, where a change in the developmental timing of a creature produces morphological changes is called heterochrony, and paedomorphosis is one example of it," Abzhanov explained.
Ontogeny discombobulates phylogeny: paedomorphosis and higher-level salamander relationships.
Such extreme sexual dimorphism involving paedomorphosis is unique among siboglinids, as all other known species of frenulates and vestimentiferans have equal-sized sexes (Ivanov, 1963; Bakke, 1990; Gardiner and Jones, 1993).
Such traits include cyclomorphosis and other dimorphisms associated with protective structures ("protective" dimorphisms), paedomorphosis, diapause, some cases of sex determination (e.
This feature is present in species with protracted juvenilism (also termed paedomorphosis, which implies sexual reproduction while in a juvenile state of development).
Paedomorphosis is the condition wherein an animal become sexually mature before metamorphosis, with the result being that many larval/juvenile features are retained in the adult stage of the life cycle.
Moreover, some changes are consistent with an evolutionary quirk known as paedomorphosis, in which species retain in adulthood the youthful dimensions that their ancestors had as juveniles.
