Related to neoteny: pedomorphism, paedomorphism


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.

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.
