Definition of neoteny in English: neotenynoun niːˈɒt(ə)niniˈɑt(ə)ni mass nounZoology 1The retention of juvenile features in the adult animal. Also called paedomorphosis Example sentencesExamples - This is a classic example of an evolutionary phenomenon known as neoteny - the retention of larval or juvenile features in mature adults.
- Among early codiacrinids adaptive forms evolved initially through both neoteny and progenesis.
- This combination of characters is best interpreted as evolution through neoteny.
- In fact Neo, as he has been named, suffers from a condition known as neoteny, where juvenile characteristics, like gills, are retained into adulthood.
- Some species (for example, the axolotl) display neoteny - that is, the larval features persist into sexual maturity.
- 1.1 The sexual maturity of an animal while it is still in a mainly larval state, as in the axolotl.
Also called paedogenesis Example sentencesExamples - Facultative neoteny also occurs in some species of true salamanders.
- The acquisition of sexual maturity by an animal while still in the larval stage is a process that goes under the name neoteny.
Derivatives adjective niːəˈtɛnɪk Zoology Direct-developing and normal biphasic frogs have slightly larger genomes, followed by biphasic, then direct-developing, and finally facultatively and then obligately neotenic salamanders. Example sentencesExamples - This certainly appears to be the case in neotenic salamanders, for example.
- However, the young man can take advantage of the fact that older men are also of the generation before, who are less neotenic and look more like apes.
- Humans are neotenic apes, ostriches are neotenic birds; we retain useful infantile characteristics into adulthood.
- Sermonti therefore argues that neotenic organisms - in which juvenile traits persist into adulthood, e.g. gills in adult salamanders - must be archaic, because their features appear earlier in development.
adjective Zoology The literature suggest that the frequency of neotenous newts in a population could be as low as one in 1, 500. Example sentencesExamples - The authors' conclusion was that ‘humans make poor neotenous Neandertals,’ according to Williams.
- It is unclear if other species of Rugiloricus also have this parthenogenic life cycle, but there is some evidence that both R. carolinensis and R. cauliculus may also form neotenous larvae.
- Reisinger had suggested in 1960 that Xenoturbella might be derived from a neotenous deuterostome larva based on features of the nervous system, the enteropneust-like epidermis and the spermatozoa.
- Thomas suggested that the noetiid ligament evolved from a ligament with outer chevrons only, as in Anadara antiquata, or the neotenous ligament of limopsids.
Origin Late 19th century: from German Neotenie, from Greek neos 'new' (in the sense 'juvenile') + teinein 'extend'.
