Neoteny:
The retention by adults of traits previously seen only in the young is a subject studied in the field of developmental biology, occurring in two ways. In neoteny (/niːˈɒtᵻni/ /niːˈɒtni/[1][2][3] or /niːˈɒtəni/,[4] also called juvenilization),[5] the physiological (or somatic) development of an organism (typically an animal) is slowed or delayed. Neoteny is found in modern humans. [Wikipedia]
