Neoteny - Wikipedia
WebNeoteny ( / niˈɒtəni / ), [1] [2] [3] [4] also called juvenilization, [5] is the delaying or slowing of the physiological, or somatic, development of an organism, typically an animal. Neoteny is found in modern humans compared to other primates. [6] In progenesis or paedogenesis, sexual development is accelerated.
Paedogenesis | Parthenogenesis, Reproduction, Embryogenesis
Webpaedogenesis, reproduction by sexually mature larvae, usually without fertilization. The young may be eggs, such as are produced by Miastor, a genus of gall midge flies, or other larval forms, as in the case of some flukes. This form of reproduction is distinct from neotenic reproduction in its parthenogenetic nature ( i.e., no fertilization ...

Paedogenesis | Encyclopedia.com
WebMay 14, 2018 · Paedogenesis is a form of neoteny and is particularly marked in the axolotl, a larval form of the salamander, which retains its larval features owing to a thyroid deficiency but can breed, producing individuals like itself. If the thyroid hormone thyroxine is given, metamorphosis occurs.

The adaptive significance of paedogenesis in North American …
WebPaedogenesis in varying degrees is exhibited by many species of North American salamanders, particularly of the genus Ambystoma. On the basis of a consideration of the ecology of these species, it is proposed that paedogenesis is evolutionarily adaptive and the following hypothesis is presented.
