1. The retention of juvenile characteristics in the adults of a species, as among certain amphibians. Also called pedomorphism, pedomorphosis.
2. The attainment of sexual maturity and subsequent reproduction by an organism still in its larval stage. Also called pedogenesis2.

"Brain image and tissue section analyses indicated an altered pattern of neural cell differentiation, resulting in a delayed neuronal maturation and neural fiber myelination of the transgenic monkeys, similar to the known evolutionary change of developmental delay (neoteny) in humans."

These pieces of evidence are suggestive of a form of neoteny in the female brain, (assuming male brains as the baseline, which is something scientists do), but no one had looked at metabolism -- how the brain runs on glucose -- until now.
Further, the persistence of juvenile traits into adulthood has been found to not only readily elicit helping behavior from others towards those adults who display juvenile traits, known in ethological circles as neoteny (Keating et al.
In my paper on the occurrence of protracted juvenilism (paedomorphosis; neoteny of some authors), I described the patterns seen in rosette trees, rosette shrubs, succulents, and various annuals and perennials (Carlquist, 1962).

But the differences in neoteny are critical, as they also determine significant developmental differences between our species and chimpanzees, including the development of the neocortex (see Miller, et al., 2012), which is associated with categorical and goal oriented reasoning and attention.
A commonly used salamander species, Axolotl (Ambystoma mexicanum), has lifelong lasting neoteny and does not undergo metamorphosis naturally.
Especially relevant to his view of Bildung, the latter two processes result in the retention of juvenile features in adulthood--a phenomenon known as neoteny (or paedomorphosis), which, despite its suggestion of regression, was believed to enable an evolutionary "escap[e] from the blind alleys of specialization, into a new period of plasticity and adaptive radiation" (J.
